Safe disinfection and cleaning of surfaces contaminated with biological fluids

What are dangerous surfaces contaminated with biological fluids?
Of course, the greatest danger is blood contamination. Medical personnel should always be alert to this kind of pollution, since any spilled blood can potentially contain viruses of parenteral hepatitis or HIV. In this case, contaminated surfaces can be a factor in the transmission of these dangerous infections.

Other biological fluids (saliva, sputum, vomit, feces, etc.) are not so dangerous. Surfaces contaminated with these fluids cannot cause the spread of HIV and parenteral hepatitis. However, it may well be a factor in the transmission of other infectious diseases, in particular, acute intestinal infections, tuberculosis, influenza, etc.

How is cleaning done when contaminated with biological fluids?
In medical institutions daily wet cleaning with the use of disinfectants should be carried out. When cleaning, floors, walls, doors, surfaces of equipment and hard furniture, etc. are disinfected by wiping. The best option is to use disinfectants with detergent properties, which will combine the disinfection of the surface with its washing. Of course, technicians should clean with personal protective equipment.

In general, the current cleaning in the premises of the medical institution is carried out according to the regime used for bacterial infections. However, disinfection of surfaces contaminated with biological fluids and in particular with blood must be carried out according to the regime used for parenteral hepatitis.

Before cleaning, a medical professional must inspect the premises for visible contamination with body fluids. If you detect blood spills on the floor, furniture, equipment surfaces, etc., you must first of all treat this contaminated area of ​​the room.

For small contaminants, wipe the surface contaminated with blood with a separate cloth, which is abundantly moistened in the working solution of the disinfectant. Fifteen minutes later, the manipulation is repeated.

For large spills of blood, first puddle the puddle with paper napkins or rags. After the liquid is absorbed, soiled napkins (rags) are placed in a container for hazardous waste. Then twice treated contaminated surface disinfectants. After that, they are already starting to carry out the current cleaning of the entire premises.

Effective disinfectants for surface disinfection
When choosing disinfectants, first of all, you need to pay attention to the range of their actions. So, for the treatment of surfaces contaminated with biological fluids, it is necessary to use disinfectants with a wide spectrum of action. This means that this disinfectant is effective against most microorganisms, including the HIV and hepatitis viruses.

To disinfect surfaces, we recommend using such disinfectants with a wide spectrum of action based on active chlorine, for example:

Clorox Disinfecting Wipes with Micro-Scrubbers, Bleach Free Cleaning Wipes - Crisp Lemon, 70 Count Each (Pack of 3)

Operation of chlorine disinfection plants

For disinfection of water is used chlorine in a gaseous state and in the form of compounds (bleach, hypochlorites, etc.). Chlorination of drinking water with a daily consumption of up to 50 kg, as a rule, is allowed to produce only from cylinders. With a chlorine consumption of more than 50 kg / day, both cylinders and drums-containers with a capacity of 1000 liters can be used.

The piping from cylinders or barrels is connected to vacuum chlorinators in series through a coil evaporator and a mud tank with a capacity of 50-70 liters with a siphon tube. On the collector collector between the cylinders (or barrel) on the scales and the evaporator, an eyeliner-spiral is arranged for the free operation of the scales.

Maintenance of the chlorination plant in this case consists in changing the cylinders, starting and stopping the chlorinators, and identifying and rectifying faults.

Preparation and replacement of cylinders must be carried out in a specific sequence. Before attaching the cylinder to the chlorinator, you must make sure that there is chlorine gas in the cylinder, clean the discharge tube and the valve channel from contaminants that could get there when the cylinder was filled at the factory, turn on the fan (you can turn it off only after replacing the cylinder gas leakage), put a gas mask on and put chlorine from the spare bottle into the chlorinator by opening the stop valve in the cylinder head. Without removing the gas mask, close the stop valves in the cylinder head and on the inlet tube, then release the collar at the head, remove the cylinder and transport it to the designated storage space. Without removing the gas mask, carefully transport the fresh bottle into the chlorinators room and replace the removed bottle.

When preparing the cylinder, the tightness of the connection of the supply pipe to the cylinder should be checked and the detected gas leakage eliminated. It is better to use klingerite boiled in oil as a gasket (lead gaskets break down the pipes and break up).

With several cylinders working simultaneously, the actuated cylinder can be detected by the temperature of its walls, which in this case becomes close to the room temperature; cylinders containing gas, much colder (to the touch). With one cylinder in operation, the moment of its emptying is easy to install using a pressure gauge (which in this case should show 1.5-2.0 atm).

The start and stop of the chlorinator are also carried out in a specific sequence according to the instructions for this chlorinator.

1. When starting the chlorinator, turn on the fan in the chlorinators, put on the gas mask and, after entering the room, check for gas leaks. To do this, a piece of cotton (or cloth) moistened with ammonia should be brought to those places where gas leakage is possible. The appearance of white haze, which is the result of the reaction of chlorine and ammonia vapors, will indicate the leakage of chlorine in this place.
2. Making sure that the regulator and bleed valves of the chlorinator are closed, slowly open the stop valve in the cylinder head, and then slowly open the valve on the supply pipe; as a result, the gas in the tube will flow through the filter into the pressure reducing valve. The high-pressure gauge should show in this case the pressure in the cylinder about 6 atm at 15 ° C.
3. Check for chlorine leakage from the cylinder to the chlorinator.
4. Open the shut-off valve (if any) on the pipeline that discharges the chlorine water and the shut-off valve on the pipe that supplies water to the chlorinator. Smoothly opening the starting valve at the water pressure reducing valve, let it through the mixer into the pipeline draining the chlorine water. Smoothly opening the starting valve at the pressure reducing valve for chlorine, let the chlorine flow, which, passing the gauge and non-return valve, will flow into the mixer and through it into the pipeline discharging the chlorine water.
5. When the chlorinator is momentarily stopped, it is sufficient to close the regulating valve. If the chlorinator stops for a long time, close the cylinder valve, the stop valve on the supply pipe and the regulating valve and open the drain valve. Also close the water tap.

The required intensity of chlorine gas extraction directly from the vessel should be provided by the influx of heat from the ambient air through the container wall due to natural convection or forced blowing and justified by calculations agreed with the specialized organization. It is forbidden to heat the walls of vessels with open fire and pour water. Frosting of the vessel walls is not allowed. The number of simultaneously operating vessels should not be more than two per line.

Chlorine sampling should be carried out with constant monitoring of the chlorine consumption, the end of the emptying of the tank, the pressure in the system on the lines of liquid and gaseous chlorine and to exclude the possibility of water entering the process pipelines and chlorine containers.

During the operation of water and wastewater disinfection systems, the staff must:

a) maintain the specified mode of operation of the main and auxiliary equipment, ensure their trouble-free operation;
b) monitor compliance with the prescribed consumption of disinfectant;
c) control the concentration of residual chlorine in water (waste water) in the prescribed time interval;
d) carry out an audit of chlorinators and stop valves at least once a quarter (with replacement of stuffing box), an audit of mud collectors - at least once every 2 years with two chlorinators and annually with a greater number of chlorinators;
e) in time for the schedule to carry out the outage of equipment;
e) periodically take samples of water after disinfection for microbiological analysis;
g) follow the indications of instrumentation and the functioning of automation equipment;
h) take steps to troubleshoot installations;
i) monitor the operation of ventilation systems, including emergency;
j) follow the monitoring system for chlorine content in the air of the working area;
l) keep records of the consumption of reagents, electricity, water for the own needs of disinfection facilities;
m) comply with safety requirements.
Chlorination (chlorine storage) should be equipped with systems for localizing and neutralizing accidental release. These systems should ensure the elimination of the consequences of accidents caused by the release of chlorine from one vessel of maximum capacity (container - 1000 kg, cylinder - 50 kg).

During the operation of electrolysis plants for the production of chlorine agents, in addition to the listed rules, one should be guided by the manufacturer’s instructions.

Amazon Brand - Solimo Disinfecting Wipes, Lemon Scent & Fresh Scent, 75 Wipes Each (Pack of 2)

BACTERIOLOGICAL CONTROL OF THE QUALITY OF DISINFECTION OF THE SURFACE OF EGG SURFACE

In the process of processing the surface of eggs, it is necessary to periodically monitor the effectiveness of disinfection. Samples for the study of bacterial contamination of the shell surface are taken immediately before treatment in an amount not less than

5-10 pcs. from the party, from different places, and after disinfection - in the amount of 10 pcs. from the party, pledged in the chamber or washed with disinfectants on the machine. For the examination of each egg, a sterile gauze napkin (5x5 cm), folded as a tampon, and a wide-mouth flask with 30-50 divisions with beads and with 5 ml of sterile tap water or neutralizing solution (0.1% sodium sulfite solution with 1 % solution of sodium carbonate).

The egg for the test is taken sterile (flamed) with ring-shaped ends with forceps and wiped in mutually perpendicular directions with a sterile gauze pad dipped in a flask with beads. Gauze swab with tweezers is washed in a flask, wring out and again wipe the surface of the egg shell. After re-wiping, the swab is dipped in a flask, washed with beads, and after 10 minutes they begin to examine this liquid. For this purpose, add 0.5 ml of it into two tubes with meat-peptone broth (BCH) and 6 Petri dishes, of which 3 are poured with meat-peptone agar (MPA) diluted and cooled to 40–45 ° C and 3 with Saburo agar.

The results of sowing take into account after their temperature control on BCH and MPA at 37 ° C, and on Saburo agar at 20-22 ° C after 24, 48 and 72 hours. If there is growth on MPA, after disinfection, the number of colonies is calculated and the percentage of disinfection is calculated in relation to the number of microorganisms isolated from disinfected eggs. After counting the colonies, the density of bacterial contamination is calculated on average per egg.

CLEANING AND DISINFECTION OF THE SURFACE OF SURFACE OF EGGS

To eliminate or minimize the entry of microorganisms into the egg mass (melange or white and yolk), eggs are treated with disinfectants before breaking.

For washing eggs, caustic soda (NaOH) solutions with a concentration of 0.2% or soda ash (Na 2 C0 3 ) with a concentration of 0.5%, having a temperature of 30 ° C, are used. In such a solution, the time of soaking is reduced and washing is facilitated, impurities are removed from the eggshell, even if heavily contaminated and stored for a long time.

Eggs with visually clean shells and eggs after soaking and washing are disinfected.

Disinfection is carried out by immersing eggs in a bath using a special conveyor or manually for 7-10 minutes, where the exposure to a clarified bleach solution occurs with an active chlorine content of 1-1.2% at a temperature of 18 + 2 ° C.

Solutions of detergents can be used repeatedly. The maximum allowable is a 20-fold use of the solution for 3.5 hours of continuous operation with cyclical filtration.

At low-power enterprises, the YM-3000 machine with a capacity of 3,000 eggs per hour is used for washing and drying eggs (Fig. 4.2).

Fig. 4.2. Egg washing machine YM-3000:

1 - tray for receiving eggs; 2 - drying brush; 3 - washing brush; 4 - loading tray; 5 - washing chamber; 6 - drying chamber; 7 - water heater

It works as follows. The operator loads the eggs on the inclined loading chutes, from where they roll to the intake valves, from where they get one for each turn of the auger. On the auger the eggs are fixed with brushes and guides.

Under the action of counter-rotation of the screws and brushes, the eggs are continuously rotated around the longitudinal axis and move along the machine. In the gap between the washing and drying brushes, the eggs are held on augers by special cargo shock absorbers. The surface of the eggs passing through the washing chamber is continuously washed with water at a temperature of 40 ° C, coming from the sprinklers. In the drying chamber, heated brushes wipe the surface of the eggshell, after which they fall on the transverse conveyors of the eggs. The driving pulleys of the conveyors are the cylindrical ends of the screws.

Transporters deliver eggs to the gathering table, from where another operator takes them. Contaminated water is discharged into the sewer.

For heating water, three loop electric heaters TEN-19 with a capacity of 2360 W each are installed. The stability of the water temperature in this case provides the relay TR-200. To protect electric heaters from pressure drop in the water supply network below 0.5 kg / cm 2 , the pressure switch RD-145 is provided. Thanks to the use of a fresh air heater, the service life of nylon brushes increases, maintaining the temperature only up to 40 ° C.

The machine of the brand RZ-FPM 208A has a single technological conveyor, on which all operations are carried out consistently, which makes it possible to exclude the additional losses of raw materials (eggs) that are unavoidable during transfer.

In the lower part of the welded body of the machine 1 there is a tank with a washing solution, over which a longitudinal closed conveyor 4 of reinforced rubber rollers of a special profile is mounted. The profile of the rollers corresponds to the size and shape of the eggs. The actuator 22 consists of an electric motor, a gearbox, a chain drive and a ratchet-and-ratchet mechanism, which imparts a pulsating motion to the conveyor. The upper horizontal branch of the conveyor is used for sequential transportation of eggs for technological operations. Above the upper branch are sequentially arranged the cabin for the control of eggs 14, the washing chamber 7, the drying chamber 12 and the disinfection chamber 18.

For flushing the machine, two hatchways are provided in the front part of its bed. Sanitization machine lasts about 15 minutes. The machine is served by three operators.

The six-row PMSU egg washing machine can operate both autonomously and in conjunction with an egg grading machine. It is used in large poultry farms with a capacity of 300 thousand laying hens and more.

The PIT installation (fig. 4.4) is intended for washing, disinfecting and drying eggs with their manual laying in hillocky gaskets. It consists of the following main nodes:

The receiving table is designed to receive eggs from the conveyor of the washing machine, it is installed on a special stand in front of the machine. Electrical equipment consists of a control cabinet, a device for regulating the temperature of the washing solution, an interlocking device and an emergency stop for the actuators of the mechanisms connected by communication cables.

Contaminated eggs laid with a hand-held stacker 1 on a six-row roller conveyor 2 of the MMYA-1 machine are fed to the washing box 3. Wash the eggs with a solution heated to a temperature of 40 ... 45 ° C using brushes 8 reciprocating in the vertical plane from drive 4.

The solution on the brush is fed from the tank of the machine with a water pump. From the washing box, the eggs enter the drying unit 5, where they are blown by a stream of air heated through a duct from an electric air heater 7 heated to a temperature of 60 ... 70 ° C.

After drying, the eggs from the six-row conveyor of the installation arrive at the receiving table 6, from which the operators manually stack them into the pimples.

Before the start of the installation, the solution is heated with the help of three heating elements installed in the sump of the machine.

For operation as part of an egg grading line or in conjunction with sorting machines, the installation can be equipped with a SMYA-01 ring-trailer. In this case, the eggs from the six-row conveyor of the installation come to the annular transfer unit, which forms a two-row one from the six-row flow of eggs and delivers them to the conveyor of the egg grading machine. The transfer unit consists of a frame, which is a frame, a drive sprocket unit, a tensioning device, and a transfer chain (sleeve-roller chain with a step of 15.875 mm) with special plugs for transferring eggs. The drive chain sprocket is driven by the drive of the MMYA-1 washer using a chain transmission.

For autonomous work, a modernized YAMU-A egg- washing installation is used. The egg washing machine YMU-A differs from the PIT installation by the absence of an electric air heater unit (replaced by a fan) and the SMYA-01 ring skidder in its composition, since it operates in an autonomous mode, as well as an improved design of water nozzles and a drying unit.

In addition, a strainer was installed on the suction line of the pump, a storage area was inserted on the receiving table, electrical equipment was improved, and a tray was installed to protect the operator from the air flow generated by the fan.

In recent years, the washing machine for eggs of the brand YM-5-04 has found increasing use .

This five-row machine consists of:

1) from a welded frame;
2) housing with cover;
3) systems of rotating nylon brushes;
4) rubberized conveyor augers;
5) stops;
6) detergent sprayers;
7) pallet;
8) a set of electric heaters for drying eggs;
9) loading tray;
10) unloading belt conveyor;
11) electric dryer;
12) drive with chain and V-belt drives.

The machine works as follows. Eggs are manually laid in the loading tray, from where, along five inclined guides, they enter the cleaning zone, where they are soaked. Moving along the shaft-augers, the eggs are cleaned with wet brushes, and then pre-dried with heating elements, and, entering the conveyor belt, are finally completely dried with an EP-4 electric dryer. The consumption of tap water during the operation of the machine is 50 l / h.

Freshly laid eggs with a small degree of pollution is enough to wash with warm water. For washing eggs of medium pollution, use of an aqueous solution of sodium bicarbonate — baking soda at a concentration of 0.1–0.25% is allowed; its use at a temperature of 35–40 ° C gives a good effect. Eggs with a high level of contamination require pre-locking in water or the use of special detergent synthetic detergent compositions.

Synthetic detergent formulations can be used in all types of washers and installations described. Depending on the degree of contamination, the washing time is 20-180 s at an optimal temperature of 40 ± 2 ° C and a solution concentration of 0.3%. When the processing time is less than 3 minutes, the detergent practically does not penetrate into the eggs, and after washing they have a good presentation. The consumption of the washing solution of 0.3% concentration per 1000 eggs is 50 liters.

With a slight degree of contamination of eggs allowed to reduce the concentration of detergent. To prepare the solution, use drinking water with a temperature of 45 ... 50 ° C. Washed eggs are dried in a stream of warm air at a temperature of 60 ... 70 ° C and its velocity of 3-4 m / s.

The machine for cleaning eggs M-4 (Fig. 4.5) performs washing, drying and disinfecting operations in one stream, while the eggs on the screws move in opposite directions.
Machine for cleaning eggs M-4

Fig. 4.5. Machine for cleaning eggs M-4:

7 - fan; 2 - input tray; 3 - brush; 4 - feed worm; 5 - disk

The machine consists of a body, two rubber-coated augers, brushes, loading and unloading trays, a disk unloading device, a drying fan, a folding body, and a dropper for feeding disinfectant eggs to the surface of eggs.

Contaminated eggs are placed on the input inclined tray, from where they are fed one by one with a sift for each turn of the transporting auger. Upon admission to the auger, the surface of the eggs is moistened with a disinfecting solution and treated with a rotating cylindrical nylon brush, into which a cleaning solution is fed through a perforated tube. The used solution is discharged into the sewer. From the auger of the washing zone, the eggs are fed along an inclined tray to the auger of the drying zone, which is parallel, which transports the eggs under a thinner nylon brush, wiping their surface. At the same time, for the effective removal of moisture, air is supplied to this area with a small fan. The machine is served by one operator.

For the disinfection of the shell, in the production of melange, ultraviolet irradiation of eggs with the help of bactericidal lamps is also used (Fig. 4.6).
In the production of melange

Fig. 4.6. The use of UV lamps to treat the surface of eggs in the production of melange

Studies of the effectiveness of this method have shown that most microorganisms die in 5 seconds, and sterility is achieved in 20-30 seconds. The duration of irradiation depends on the degree of seeding of the eggs by microorganisms.

Exposure of 20 s is sufficient for effective exposure to putrid microflora. However, with significant contamination by spores, complete sterility is not achieved even after 20 minutes of irradiation, although most of the spores die.

Ultraviolet disinfection, water disinfection

UV water disinfection
To date, more and more enterprises in various fields of activity prefer ultraviolet disinfection of air, water, surfaces and even food. This type of disinfection has many advantages and has virtually no disadvantages, which was the reason for its popularity. The effectiveness of this method of cleaning is directly related to the principle of exposure to ultraviolet radiation on various surfaces, as well as on all sorts of microorganisms.

The principle of UV disinfection
The bactericidal effect of ultraviolet radiation is the basis on which such equipment is based. Electromagnetic waves in the invisible part of the spectrum, detrimental effect on harmful microorganisms. Any pollution caused by living organisms, whether bacteria, viruses, fungi or yeast, can be eliminated without any problems with the help of ultraviolet rays.

Electromagnetic waves, whose length lies in the range of 200-280 nm, have the most effective bactericidal effect. This is the range used by manufacturers of UV equipment. Penetrating into the cells of the microorganism, such radiation destroys it, preventing further activity and reproduction. Ultraviolet waves act directly on the DNA of the cell, breaking its bonds. Some microorganisms can develop radiation resistance over time, so even after installing the equipment, it is necessary to periodically monitor the composition of water or air and take appropriate measures to detect the growth of bacteria or viruses.

The effectiveness of this type of disinfection depends on which microorganisms are present in the air, water or on surfaces. Each type of microflora responds differently to UV rays, differing in greater or lesser sensitivity. In addition, many other factors affect the quality of cleaning:

humidity and dustiness of air;
room dimensions;
surface types, etc.
It is desirable to select disinfecting equipment individually and with the help of a specialist. NPO ENT is engaged in the manufacture of custom-made UV equipment tailored to the requirements of each client.

Ultraviolet affects only living microorganisms, but does not affect the chemical composition of air, water and coating of various surfaces. UV equipment does not help to remove dust from the air, change its humidity or filter water from various additives. The task of our recirculators is to conduct disinfection and disinfection procedures.

Degree of safety for humans
Ultraviolet radiation affects people. With uncontrolled doses, you can burn unprotected skin or retina. However, in the production of disinfecting equipment, it is taken into account that people work in most of the processed premises. For such cases, recirculators of the closed type are produced, which do not emit ultraviolet into space, but pass air through themselves. Thus, the air at the entrance is contaminated with microorganisms, and at the exit it is cleaned and disinfected. Such equipment can be used in the presence of people.

However, disinfection does not mean cleaning the air only. Most often, surfaces, water, or even food in food warehouses are subject to decontamination. It is impossible to pass them through a recirculator, therefore in these cases open installations are used. When operating such equipment, UV rays freely propagate through the room, falling on all surfaces. It is not safe for a person with open skin and unprotected eyes near such an installation. Therefore, most often such equipment is turned on during the absence of people. It is also convenient in such periods to combine the action of ultraviolet processing and ozonation of air, which is unacceptable in the presence of a person.

If the presence of a worker with the UV equipment on is mandatory or an extraordinary situation arises when an open recirculator is in operation, this can be easily solved with the help of a small barrier between the skin and the air. Since the wave of this spectrum does not penetrate even through the slightest obstacle, you can protect yourself from radiation with thick clothing, cream with UV filters for exposed skin, as well as ordinary sunglasses.

UV applications
Due to their versatility, ultraviolet installations are preferred in almost all areas of human activity. Equipment maintenance does not require special knowledge or the presence of a special worker, so the purchase of ultraviolet recyclers is also economically beneficial.

This method of cleaning and disinfection is widely used in areas such as:

Medicine, which became one of the first industries where they paid attention to the disinfecting properties of the ultraviolet. Quartz lamps and disinfecting devices are used for the treatment of both premises and medical instruments. In addition, special lamps are used for the direct treatment of skin diseases caused by fungi. The value of UV equipment for medicine is difficult to overestimate, because it is here that microorganisms can cause the greatest harm.
Water treatment facilities. Water is the basis of life, therefore, it is very important that the population receive it as clean as possible. At water purification plants, UV installations are sometimes used in combination with chemical treatment methods. Ultraviolet enhances and improves the disinfection provided by chemicals.
Pools. Popular chlorination fades into the background, because the active chemical is irritating to human skin and destroys not all microorganisms. While UV disinfection of water in the pools allows to achieve its maximum microbiological purity and does not affect the health of visitors.
Food industry. In order to prevent the ingress of microorganisms into food during their manufacture and packaging, it is important to disinfect surfaces, materials and products as accurately as possible. The use of ultraviolet equipment allows you to negate the damage to products due to ingress of fungi, yeast or bacteria. Thanks to this cleaning, you can guarantee the safety of products throughout the shelf life, as well as its safety for the consumer. In turn, enterprises reduce their losses due to spoiled goods.
Agriculture. Installing UV equipment in food warehouses allows you to extend the shelf life of vegetables, fruits, grains and many other products. Disinfection of air and surfaces does not allow to develop rotten and moldy processes without harm to products. In addition, the use of such cleaning in poultry farms and livestock enterprises reduces the degree of disease of poultry and livestock, which is much safer than the use of chemicals and medical preparations.
Purification of air and wastewater in enterprises not related to the food industry. The installation of UV disinfection in workshops, laboratories, and water treatment plants not only makes the work of people at these enterprises safer, but also significantly reduces harmful emissions into the environment, improving the environmental situation. It is also important to disinfect wastewater on ships.

Fisheries. To protect the population from acquiring contaminated fish, it is important to disinfect the reservoirs in which it is bred. UV installations are best suited for this purpose — by destroying pathogens, they do not affect the chemical composition of the water and the condition of the fish.
Advantages of UV disinfection
The use of ultraviolet radiation to disinfect air, water and all kinds of surfaces has become widespread. This is due to the advantages of this type of cleaning:

UV radiation has proven to be effective against most microorganisms, many of which are resistant to chemical attack. By negating the ability to multiply, ultraviolet stops the destructive activity of bacteria, viruses, fungi and yeast.
Disinfecting equipment of this type does not change the properties and chemical composition of the treated objects. This is especially important when disinfecting food, water and air.
Due to the ultraviolet equipment installed in the food industry and food warehouses, it is possible to increase the shelf life of products. When UV processing does not change the taste and nutritional qualities of vegetables and fruits.
The equipment does not require additional maintenance staff, because in most cases it works in automatic mode.
Depending on the type of room and its purpose, you can choose different models of UV emitters, including safe for people.
The environmental friendliness of the equipment plays an important role in the use of disinfecting facilities at the sites of wastewater discharge, as well as in medicine, animal husbandry and other areas directly related to human activity and its environmental impact.
The company NPO ENT offers the manufacture of ultraviolet installations for all applications. Our specialists approach each order individually, therefore the client receives equipment developed for a specific object. For UV disinfection of water, it is necessary to know its flow rate, purpose (drinking, process, wastewater), pressure, placement conditions, etc.

When ordering UV equipment for disinfection of premises, it is necessary to know the size and volume of the object to be subjected to disinfection, its purpose (warehouse, workshop, medical institution, food industry enterprise, etc.). Also taken into account are indicators of air composition (humidity, dust).

Experts NPO ENT provide expert assistance in ordering equipment. We also guarantee quality service and provide instructions for the operation of installations.

Disinfection of contaminated surfaces, sanitizing people

As a result of the use of weapons of mass destruction by the enemy, pockets of radioactive, chemical, and bacteriological contamination may occur. Under these conditions, people, animals, as well as territory, workplaces, apartments, and other materiel may become infected. Therefore, in order to eliminate the possibility of injury, it is necessary to carry out work on disinfection and sanitization.

Disinfection - decontamination, degassing and disinfection of infected surfaces.

Decontamination is carried out during contamination with radioactive substances and has the goal of removing them from infected objects to the permissible infection rates.

Decontamination consists of disinfecting toxic substances and their removal from contaminated surfaces.

Disinfection refers to the destruction of pathogenic microbes and the destruction of toxins.

Sanitary treatment of people - is the removal of radioactive and toxic substances, as well as bacteriological agents from the skin and mucous membranes of humans. When people sanitize people, decontamination, degassing and disinfection of clothes, shoes and personal protective equipment is carried out.

Depending on the conditions of holding, the availability of time and the means available, measures for decontamination and sanitization are divided into partial and complete. Partial measures for the decontamination of materials and sanitation of people are prophylactic. They are carried out during chemical contamination directly in the lesion, and in case of radioactive contamination, after exiting the lesion. Full disinfection is carried out at stationary washing points, clothes disinfection stations, as well as at special treatment points (platforms) deployed outside the lesion focus.

Means used for decontamination Deactivating substances and solutions
It is known that radioactive dust formed during ground-based nuclear explosions consists mainly of melted particles of an inactive carrier — soil materials, in which the radioactive isotopes are concentrated in mass and on the surface of which. It is difficult to separate these isotopes from the carrier, to wash it with water or to remove them with the help of deactivating substances. Therefore, the completeness of the decontamination of infected objects mainly depends on the connection of the carrier particles with the surface or material being deactivated, and the deactivation itself amounts to removing the maximum number of carrier particles.

Methods for the removal of radioactive contamination using deactivating substances in the processing of infected objects are different. They are chosen depending on the nature of the objects being decontaminated, the characteristics of the materials from which they are made, the conditions of the decontamination, the availability of the necessary means and other factors.

These removal methods are usually based on certain physicochemical processes, similar to those widely used in the removal of ordinary pollutants in various sectors of the national economy and in domestic conditions.

For decontamination apply substances that contribute to the removal of radioactive contamination, increasing the efficiency of the washing process, the complex formation and dissolution, sorption or ion exchange. In accordance with this, many surface-active (detergent) substances and preparations, complexing agents, acids, alkalis, sorbents, ion-exchange materials are referred to as deactivating substances.

Clorox Disinfecting Wipes Value Pack, Crisp Lemon and Fresh Scent - 3 Pack - 75 Each

Disinfecting the premises (the premises are cleaned by the residents themselves)

Disinfection facilities:

the surface of the premises (floor, walls, doors);

dishes;

underwear;

toys

Methods of disinfection:

surfaces of premises (floor, walls, furniture) are wiped or irrigated;

dishes, linens, toys soaked in a disinfectant solution.

Chlorine-containing preparations (chloramine, DP Altai, DP-2T, Dekhlor, Deochlor, etc.) are used to treat the premises. Working solutions are prepared in plastic (enameled) or glass containers by dissolving the required amount of disinfectant in water. Prepare solutions for the regime of viral diseases.

Example 1: for the preparation of a 3% solution of chloramine, it is necessary to take 300 g of chloramine per 10 liters of water. The consumption of the working solution when wiping is 150 ml per 1 sq. M. m, with irrigation hydropult - 300 g per 1 square. m, with soaking dishes - 2 liters per set, while soaking dry clothes - 4 liters per 1 kg. Exposure time (exposure) - 30 - 60 minutes. After the specified time (30 - 60 minutes), rinse with clean water. Total, as an example, for the processing of a single house of 200 square meters. m (without area) will require 60 l of the working solution, that is, 60 l of water and 1.8 kg of chloramine or 6 packs of 300 gr each.

Treatment of outhouses, cesspools and dustbins

The simplest and most accessible method of disinfecting cesspools is the treatment with the use of chemicals. For chemical treatment of cesspools (toilets), any chlorine-containing products can be used both in dry form and in solution.

Processing is carried out by pouring any chlorine-containing disinfectants (bleach, chloramine, calcium hypochlorite neutral (NGK), sulfochlorantin, DP-2T, Dezkhlor, DP Altai, etc.).

The preparation of the disinfection solution is carried out in accordance with the methodological recommendations on the use of the disinfection preparation, and the concentration of the solutions should be at least 5%.

Example: to prepare a 5% working solution of chloramine, you need to take 500 g of chloramine and dilute it in 10 liters of water. Pour the contents of the cesspool (toilet) at the rate of 2 liters per 1 square. m sewage. That is, if the area of ​​the sump is 5 square meters. m, then per one cesspool requires 10 liters of working solution when 500 g of chloramine is dissolved in it.

When using dry powdered chlorine-containing preparations, fill the sewage at the rate of 200 g of the preparation per 1 kg of sewage. That is, for 1 (one) outdoor installation use approximately 1 - 2 kg. It is also possible to treat with a 10% solution of bleach or bleach with heat-resistant bleaching lime, a 5% solution of NGK, or a 7% solution of HKT. Consumption rate - 500 ml / sq. m, exposure time 1 h.

Lysol Handi-Pack Disinfecting Wipes, 320ct (4X80ct), Lemon & Lime Blossom

Express Disinfection

Means for the express disinfection
Any surfaces with which we come into contact are covered with microorganisms, including harmful ones. For example, in a layer of dust that accumulates on surfaces, bacteria and viruses multiply. At each contact with the desktop, upholstery of the machine, computer keyboard, medical equipment, the transfer of microorganisms occurs through the hands and other parts of the body. In this case, the risk of infection with infectious or viral diseases is high.

In such a situation, it is not always sufficient to simply keep the rooms clean. Wet cleaning, even with the use of detergents, does not destroy harmful microflora on surfaces. Using disinfectants can destroy most bacteria and viruses. But it is not always possible to clean the room, especially if you are not at home. Particularly important to the disinfection and hygiene rules are in the period of epidemics or when a sick person appears in the house. In this situation, express disinfection of surfaces is the most convenient and fastest option for disinfecting living quarters, office, medical institution.

So what features of tools for rapid disinfection make them so effective?

Means for the express disinfection are ready-made solutions for disinfection or other forms ready for use. That is, unlike traditional disinfectants, they do not need to be cooked, diluted with water, mixed components, and so on. They are always and at any time ready to use.
Means for the express disinfection can be purchased in a convenient package for quick use.
The use of disinfectants for disinfecting surfaces is always done by wiping, spraying or soaking. If we are talking about the surfaces of premises, equipment, then with express processing, the ready solution for disinfection is sprayed onto the surface and remains there for the duration of the exposure (usually not more than 3 minutes). It is not necessary to wipe the surfaces after spraying disinfectant, the amount of the product is small. Disinfecting and cleansing wipes are even more versatile and convenient to use. Just wipe the surface with such a napkin, and after 3 minutes most of the bacteria and viruses will die. This increases the cleanliness of the home or office and significantly reduces the risk of viral and infectious diseases.

So, means for rapid disinfection are mainly of two types:

Aerosol Spray Disinfectants
Disinfecting and cleansing wipes
High-quality destruction of bacteria and viruses is necessary primarily in medical institutions, including to prevent the spread of nosocomial infections. Express disinfection equipment allows you to quickly clean up contaminated surfaces, and after each patient. Conducting an express disinfection eliminates the need for long-term operation of traditional ultraviolet lamps - modern disinfectants disinfect surfaces for one to two minutes. Such treatment can be used in the presence of patients - disinfectants are completely harmless to human health.

Antibacterial express surface treatment must be carried out in public places. Including reception of large companies and organizations, offices and shopping centers, catering enterprises. Be sure to buy disinfectants and have them in public places that are easily accessible for quick use. We offer such popular means for rapid disinfection as Avancept Spray, Avancept Wipes, Almadez Express and many others. Disinfectants are always available at affordable prices. Delivery to all regions of Russia.

5 means for disinfection of the apartment

Disinfection of an apartment is a series of procedures aimed at the destruction of microorganisms that have a negative impact on human health, can damage property and be inaccessible for perception.

The timely implementation of this procedure helps prevent the entry of viral and intestinal infections.

Apartment disinfection methods
There are three main methods:

Physical (using specialized equipment and properties of ultraviolet radiation).
Chemical (various solutions, vapors, chemical preparations are used).
Biological (using the achievements of genetic engineering and the discovery of microbiology).
The correct choice of method, mode and set of tools for organizing this procedure ensures its effectiveness.

Disinfection is required in case of a change in the owner of the apartment, finding a seriously ill patient or the death of one of the tenants, as well as when a fungus appears in the apartment.

[tip] Preventive option should always be carried out regularly. This is the usual wet cleaning with the use of cleaning products with bactericidal additives. For example, you need to regularly clean the carpet so that it does not collect allergens. [/ Tip]

Disinfecting the fungus on the surface
Disinfection fungus The treatment of a fungal infection must be accompanied by disinfection of everything that the fungus could come into contact with. This is cleaning dishes, walls, floors, bathrooms, personal belongings of the patient.

Disinfection of the fungus can be done at home.

Bath disinfection
Process the bottom and walls of the bath with a mixture that can be prepared as follows: dilute equal parts of laundry detergent and 5% solution of chloramine to a creamy consistency.

Rinse off after 30 minutes.

how to clean the microwave inside
Did you know that the inside of the microwave is covered with a special reflective coating? Therefore, to clean the microwave inside , never use iron grids and hard substances.

Even pans with non-stick coating, from the outside are covered with soot. In this article, you can read how to clean the pan from the scale.

Shoe disinfection
Treat shoes with acetic acid solution 40% or formalin 25%. To do this, carefully wipe the sides of the shoes and insoles with a swab moistened with a solution.

See also: Antiseptics and disinfectants in everyday life
Then put a tampon in a shoe sock, and place the shoes in a sealed cellophane for a day.

After this procedure, wipe the shoes with ammonia to get rid of the pungent smell of acetic acid or formalin.

Linen disinfection
The most effective and at the same time simple way to disinfect linen, socks, stockings, and pantyhose is the usual boiling of things in a solution of soap and soda for 20 minutes.

After that, you should iron the linen with a well-warmed iron.

You can also use a solution of 100 g of hydrogen peroxide with water heated to 60 ° C (11-12 liters). Immerse the laundry in the solution, bring it to a boil and boil the laundry for 15 minutes, stirring constantly.

Fight against viruses and bacteria in the house
Fight against viruses and bacteria Often it is necessary to disinfect the room where children and other family members are infected with the flu or infectious diseases.

To implement this event, we recommend starting with a wet cleaning of all surfaces. It is better to carry out wet cleaning every day by adding disinfectant solutions to the water.

After cleaning, be sure to disinfect the air. Often for this reason it is enough to ventilate the apartment.

[note] Remember: for bacteria and viruses, the most favorable conditions are dry warm air. Therefore, ensuring a normal level of humidity and air temperature in the room is a guarantee of the destruction of pathogens.

Under the influence of oxygen, many bacteria die under normal conditions. Do not neglect the disinfecting force of oxygen during a walk! [/ Note]

You can carry out disinfection of the apartment and the air, using a quartz germicidal lamp . Turn on the lamp every 6 hours for 15 minutes. The device also helps to destroy the fungus.

With the lamp on, all people in the room must be led out.

Disinfection of water is of paramount importance. It is drinking water that spreads hepatitis type A, dysentery, typhoid fever, cholera and other infections.

Therefore, be sure to boil water before drinking. 10 minutes is enough to kill all living microorganisms in the water. Be sure to clean the kettle from scale in time .

folk remedy for blockages Do you have a sink clogged, but there is no plunger or plumbing cable at hand? Use a folk remedy for blockages in the sink.

Need to clean the sheepskin coat, but do not trust the dry cleaning? It describes how you can clean the sheepskin coat at home.

And if you have a fur coat, you should be twice as attentive when carrying out cleaning. Read the link on how to choose a fur cleaner, quite effective, but one that does not harm an expensive product.

Effective cleaning chemicals
Chlorine
Effective means for disinfection
This is a highly effective disinfectant with a specific smell.

A small amount of chlorine that gets into the air of an apartment during wet cleaning is absolutely harmless to human health.

Confirmation of the valuable disinfecting properties of this substance is the fact that workers in chlorine production shops rarely get the flu.

Monochloramine
It is a white crystalline substance. Effectively used for wet cleaning and disinfection of bedbugs . To prepare the solution, it is necessary to dilute 200 g of monochloramine in 20 liters of water.

Then process the surface of sinks, toilet bowls, walls, floors painted with oil paint or covered with ceramic tiles moistened with a sponge in a solution.

Bleaching powder
It is a powdered product containing 25% active chlorine.

It is used when cleaning the cesspools, outdoor latrines, places with rotting garbage.

inkstone
The solution of ferrous sulfate is used for processing wooden parts of vegetable stores, greenhouses and other wooden buildings.

The solution is prepared as follows: dilute 250 g of the substance in 1 liter of water.

men's shoes suede Suede shoes can not be covered with good shoe paste with wax, so without special care, in wet weather, it quickly gets wet. Therefore, winter men's shoes made of suede should be soaked with a special water-repellent agent.

The easiest way to clean the sole of the iron from the burn using a special pencil, but you can use and folk remedies, details on the link .

You have a blockage in the toilet, but you can not call a plumber? Read here what you need to use tools from clogging the toilet.

Disinfection of ventilation in the house
Unsatisfactory operation of the ventilation system is manifested in the following signs: strong fogging of windows, stale air in the apartment, a large accumulation of dust on surfaces.

This indicates that ventilation is required.

For this event, a special brushing machine is used to help free ventilation ducts from dust and fat deposits, as well as using a vacuum cleaner to collect all the dirt. Sometimes a partial disassembly of the ventilation system is required for better cleaning of hard-to-reach duct parts.

[tip] After cleaning it is necessary to disinfect the ventilation. To do this, dissolve some dishwashing liquid in the water, moisten the cloth in the solution, wrap up the cloth with this cloth, and gently wash the ventilation ducts. [/ Tip]

As a result of regular carrying out all the necessary measures for the disinfection of an apartment, you will be able to maintain your housing in satisfactory sanitary conditions, without exceeding the permissible norms of the number of pathogens.

Take care of your health!

Disinfectants for surfaces and floors

Often, the transmission of infections that is directly related to the provision of medical care is carried out with close contact of the infected surface with the human palm. In practice, this is possible if the health worker's hand touches the area contaminated with microorganisms. This species is a direct causative agent of infections and reproduces superbly on various objects, whether it is a piece of furniture or an attribute of medical equipment.

The closer to the patient is the surface infected with bacteria, the more likely the infection. In this regard, carrying out disinfecting works in rooms and on objects of a hospital interior, in fact - important and obligatory procedure.

According to the information prescribed in SanPiN / 2.1.3.2630-10 “Sanitary and epidemiological requirements for enterprises engaged in medical practice” / preventive disinfection can be of several types:

well-established disinfection
disinfection according to indications (epidemiological and / or sanitary and hygienic)
Preventive measures (routinely) are carried out permanently in health care facilities, but only if no nosocomial infection was detected, that is, a breeding ground for bacteria, like the provoker itself, was not detected, with the aim of

reducing the number of microbial organisms (in nosocomial conditions)
prevent the emergence of a breeding ground for bacteria
prevent the transmission of bacterial organisms through medical devices, skin of medical staff and patients
At the time of the implementation of planned disinfection in health care facilities, they disinfect all the existing surfaces inside the hospital, which allows for maximum death of various types of microbacteria, and also significantly reduces contamination of various objects with microbacteria. This means that harmful bacterial organisms are released into oxygen, household items, cutlery, tools and other hospital attributes.

The implementation of preventive measures for disinfection according to epidemiological indications is carried out taking into account the characteristics of a particular type of infection identified in the nosocomial room. A number of factors are also taken into account:

incubation period
microorganism resistance
the duration of the survival of the pathogen on objects
Quite a different situation if disinfection takes place (for the purpose of prophylaxis) according to sanitary and hygienic indications. The range of such actions is carried out as a one-time event and it is in those premises / enterprises whose condition leaves much to be desired and unsatisfactory appraisal judgments have been received from specialized specialists.

The use of detergent disinfectants for current and general cleaning

Scheduled regular room disinfection procedure is divided into daily and general.

General cleaning is done with the intention to get rid of sewage and reduce the number of infectious bacteria in the building. During the main cleaning, all surfaces are completely washed out, cleaned and disinfected (taking into account places that are difficult to penetrate), furniture, doorways, installations and devices (including lamps and chandeliers) with the use of soap and processing agents, and airspace disinfection.

General cleaning of functional rooms, medical rooms and hospital wards is done on a schedule at least every four weeks; operating rooms, dressing rooms and procedures and manipulations, delivery rooms, places allocated for sterilization - once every seven days.

During the main cleaning, the order of use of disinfecting solutions is calculated with deduction of the stationary profile and bacterial contamination.

In accordance with SanPiN 2.1.3.2630-10 “Sanitary and epidemiological requirements for organizations engaged in medical activity”, the stages of the main clean-ups consist of:

Preparing the rooms and preparing the staff for cleaning (they should have special clothes and protective personal belongings - a bathrobe, cloth covering the head and covering the face, rubberized gloves and an apron, etc., signed cleaning equipment and sterile textile rags);
Washing and disinfecting all surfaces with a floor disinfectant / sprinkling / cleaning (walls - at least two meters; fully operational;);
Washing the disinfectant for cleaning with a sterile textile cloth, using ordinary water at the end of the disinfection prevention, only after changing the workwear.

* Extract from the plan of the updated SanPiN 10.15.

During the implementation of the main cleaning of the premises, the disinfecting solution is coated on the walls by sprinkling or rubbing at a height of at least two meters (fully operational), frames, doorways, all surfaces and devices. At the end of the disinfection procedure (the staff is obliged to change the form), each surface is wiped with sterile textile rags, using ordinary water (not counting the solutions, the instructions for which indicate that they do not require washing), after which the air in the rooms is filtered.

Chemicals for disinfecting activities. The sequence of applications on various surfaces of medical devices (surgical, obstetric and dental category)

The sequence of applications of a chemical preparation for various surfaces is determined by the unity of this kind of interrelated aspects:

Profile direction of a room
The category of the probability of infection and the microbial variety of microbial contamination
Specific features of the medical activity
In accordance with SanPiN 2.1.3.2630-10, disinfection of surgical and obstetric profile objects is carried out as follows:

According to the information from the clinical guidelines (at the federal level) on the choice of disinfecting chemicals for surface sterilization, which are used in medical institutions ”(FKR), (M., 2015, 67 p., Approved at the All-Russian Scientific and Practical Conference of Infections Control Specialists, related to the provision of medical care on November 19-21, 2014, at the General Meeting of Members of NP NASKI (Protocol No 6 of November 19, 2014) and agreed by the Profile Commission of the Ministry of Health of the Russian Federation on Epidemiology (Protocol No 4 of November 20, 2014 ), reviewed and accepted by the principal supernumerary employee profile epidemiologist Health Ministry Briko NI) p. 6.6. In specialized medical institutions of the infectious profile, they use such chemicals for disinfecting action that are effective against the respective types of microorganisms:

tubal dispensaries / where there is a component that has a tuberculocidal effect with a mandatory mention in the instructions for the drug that this drug has been tested for "Mycobacterium terrae" /
mycological / constituent component capable of exerting a fungicidal effect on fungal bacteria of the genus Trichophyton.
Chemicals used for disinfecting measures must meet a number of requirements:

High drug efficacy
The drug must be safe
Ideal physical and chemical functionality
Antibacterial action should be maintained at the proper level (in the presence of various kinds of organic substances)
Lack of the fixing effect of pollution on a subject
No repellent odor
The absence of components that provoke the appearance of allergic reactions in humans
Low toxicity of the drug
The presence of detergent components in disinfectants with detergent effect
Compatible with other types of detergents
Do not cause damage to the surface of the material that can be processed
The main substances in the composition of the means for disinfection, recommended for use:

Cationic surfactants - Quaternary ammonium compounds (QAC), guanidine derivatives and tertiary amines are actively used in medical institutions for sterilization because of their advantages over other similar substances:
do not require special storage conditions and are highly soluble in water;
keep the quality of processed items;
contain the washing element, therefore, there is no need to use the special separate washing substances;
have a neutral odor, are not volatile and toxic when inhaled by personnel;
quickly erode and wash off, leaving no residue or odor on the surfaces;
According to FKR p.5.5. Quaternary ammonium compounds are not effective in combating bacteria that cause tuberculosis. Derivatives of guanidines are not as such; therefore, it is not necessary to choose and use QAC compositions with these substances. In accordance with the FCR p.5.7. they possess minimal sporicidal activity; therefore, the agents whose key substances are QAS, guanidines, amines and compositions of these compounds, regardless of their amount in the solutions used, are ineffective in the fight against microbial spores. Means based on the substances described above are not allowed to use for disinfection of objects affected by spores, the TLD of medical devices and the disinfection of medical devices.

Oxygenated components are represented by such compounds:
peroxide;
potassium fluoride peroxyhydrate;
perborate;
percarbonate.
Possess the following actions:

tremendous antibacterial activity
do absolutely no harm to others (due to the rapid decomposition into 2 elements: oxygen and water)
there is no need for long-term ventilation and washing of the treated item
Chlorine-active chemical compounds include increased antimicrobial activity in relation to all existing varieties of microbacteria, including the well-known bacterial spores.
To the above, we can add that the existing restrictive framework in relation to the conduct of disinfectant measures on various surfaces and objects, with the use of chlorine-containing drugs, is associated with the presence of a strong odor. The repellent fragrance has a somewhat negative effect on the mucous membranes of the eyes and respiratory tract, as well as on the treated surfaces, the appearance of corrosion and discoloration.

Today, the least dangerous forms of drugs containing chlorine-active ingredients are tablets and granules.

Aldehydes, as well as bacterial spores, are characterized by a wide spectrum of antimicrobial activity; they are able to interact with various types of surfaces. However, they are not used as disinfectors for indoor surfaces for the following reasons:
due to the absorption of aldehyde surfaces, they are released into the air for a long time, causing a harmful effect on the human body. It takes a long time to ventilate the room and clean the surfaces with running water;
have a fixing effect, resulting in organic matter remains on the surface, which is not effective disinfection.
Minimizing the disadvantages of aldehyde, it is used for disinfection of areas not contaminated with organic matter. Combined preparations, the components of which are aldehydes and QAS, are used to disinfect surfaces. Due to the synergistic effect, these two compounds disinfect the surface, destroying microbes and are used as a detergent disinfectant.

It is no secret that all the microorganisms in the world are arranged in such a way that they adapt very easily to various environmental conditions, in particular, to the effects of antibacterial drugs, which include various types of antibiotics, detergents and skin antiseptics known to us.

Conditions that fully influence the formation of biocide resistance require the most accurate and versatile approach and analysis of the information received, as well as explanations from a scientific point of view and reasoned evidence of evidence based on the experiment.

I would like to separately note a scientifically proven fact regarding the resistant resistance of bacteria to various drugs: the active influence of low, ineffective concentrations of various disinfectants to clean objects.

To date, there is an established list of disinfectants recommended for cleaning and destroying bacteria from various objects. The presence of minimal concentrations of various solutions is guaranteed to lead to the elimination of bacteriophages.

According to the data of their current SanPiN / 2.1.3.2630-10 "Sanitary and epidemiological requirements for organizations engaged in medical practice" p. 1.9. / established methods to promote the rotation of disinfecting solutions in various medical institutions. The most important task is to prevent (at the maximum level) the probable appearance of various strains of microbacteria that are resistant to antibacterial drugs.

It is extremely important to carry out permanent monitoring of the factor of resistance of hospital strains to actual disinfectants (with their subsequent rotation).
