Safe Operation

1. General safety requirements

The heads of linear facilities are responsible for ensuring that workers carrying out disinfection work comply with personal safety rules when preparing a disinfection solution and its use.

The disinfectant solution is prepared from grade A and B bleach, which is a white powder with a chlorine smell. Chloride of lime is a strong oxidizing agent; upon contact with organic substances, it can lead to charring, discolors fabrics, and damages metal products. If ingested, it is a hazardous substance of class III hazard. In dry form and concentrated solutions may cause irritation to the skin, mucous membranes of the eyes and upper respiratory tract.

2. Safety requirements before starting work

For the purpose of disinfection, a cleared solution, bleach-lime milk and bleach powder are used. To prepare a 10% or 20% cleared (mother) solution of bleach, 1 or 2 kg of bleach, respectively, is mixed with a small volume of water to form a slurry and the remainder of the water (up to 10 l) is added and mixed until a homogeneous suspension is formed. The suspension is left to thaw in a dark glass or enamel container with a tight lid for 24 hours. The cleared bleach solution is carefully poured or filtered into a clean container and stored for no more than 7 days.

A working 1% solution is prepared from a cleared (mother solution) by dissolving it in chlorine water at the rate of 1000 g of a 10% mother solution per 10 liters of chlorine water. The solution is prepared immediately before use. It is allowed to store unused solution for 24 hours after preparation in a container with a tightly closed lid.

3. Safety requirements during work

The areas of the room (floor, walls, doors, window frames) and furnishings are irrigated or thoroughly wiped with rags, which are moistened with a 0,5% solution of bleach at the rate of 0,3 liters per 1 m2, and sanitary products (washbasins, toilets, urinals) 0,5 .1 l per 2 m30. After disinfection, wet cleaning and thorough ventilation of the premises are carried out for 10 minutes in the absence of people in the room. External toilets are treated with a 0,5% bleach solution at a rate of 1 liters. per 2mXNUMX.

Persons with hypersensitivity to chlorine are not allowed to work with bleach.

Work on preparing a working solution of bleach must be carried out in compliance with personal safety measures, ensuring protection of the respiratory system, skin and eyes - work in protective clothing (robe, cap, apron made of rubberized fabric, rubber gloves, rubber shoes), in safety glasses type PO -2, PO-3 or monoblock, in a respirator RU-60M or RPG-67 with a cartridge of grade B or similar.

4. Safety requirements upon completion of work

During disinfection, it is forbidden to consume food, drink, smoke.

After finishing work, wash your face and hands thoroughly with soap and water.

Bleached lime is transported by road in compliance with safety precautions in closed containers or original packaging.

Store bleach in packaging or closed containers in well-ventilated, dry, concrete-covered areas away from sources of open flame and heat. There should be no unauthorized persons in the storage rooms.

5. Safety requirements in emergency situations

In case of accidental contact of the drug with the eyes, rinse them with a 0,5% sodium thiosulfate solution and then with running water for 10-15 minutes. and consult a doctor.

If lime accidentally gets into the stomach, rinse it with water (drink several glasses of water) and then milk.

If the drug accidentally comes into contact with the skin, rinse the affected area of skin with running water.

If the respiratory tract is affected, it is necessary to take the victim out into fresh air or into a ventilated room, provide peace, warmth, free him from tight clothing, give him water to rinse his mouth, throat, nose, and give him milk to drink.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
