Safe Operation

Introduction

This manual has been drawn up in accordance with the requirements of:

• POT RM-027-2003 "Intersectoral rules for labor protection in road transport";
• TI R M-014-2000 "Typical instructions for labor protection for workers performing loading and unloading and storage work with flammable, explosive and dangerous goods in handling."

The instruction establishes the requirements for labor protection when handling antifreeze - a coolant (coolant) used for internal combustion engines or as a working fluid in other heat exchangers.

1. General requirements for labor protection

1.1. Work with antifreeze is allowed for workers who do not have medical contraindications, who have been instructed in labor protection and trained in safe practices when working with coolants, safety measures during their transportation, receipt, storage, issuance and use.

Persons under 18 years of age, pregnant women and nursing mothers are not allowed to work with antifreeze.

1.2. Antifreeze contains ethylene glycol (EG), which is toxic. According to the degree of impact on a person, they belong to the third class of danger, i.e. to moderately hazardous substances. Ethylene glycol can enter the body through the skin. The maximum allowable concentration (MPC) of antifreeze in the air of the working area is 5 mg / m³ for ethylene glycol. Due to the low volatility of ethylene glycol, antifreeze and auto fluids do not pose a risk of inhalation poisoning. Therefore, when working with them, special measures to protect the respiratory tract, as a rule, are not required. Coolants do not have cumulative (accumulation) properties. The most dangerous is ethylene glycol if you drink it, the lethal dose is from 35 cm³ (depending on the weight of the person), in antifreezes (ethylene glycol solutions with water) - depending on the concentration - the average is a lethal dose of 50-100 g.

1.3. In order to exclude the possibility of using antifreeze for other purposes, the management of the organization or unit appoints a person responsible for the procedure for its storage, transportation and consumption.

1.4. Antifreeze should be stored in a closed, dry, unheated room in a special container (factory, in serviceable metal hermetically sealed cans and barrels with screw caps). During transportation and storage, all drain, filling and air openings in the container must be sealed. Empty containers must also be sealed.

The rules for storing used antifreeze are the same as for fresh.

1.5. On the container in which antifreeze is stored (transported), and on the empty container from under it, there must be an indelible inscription in large letters "POISON", as well as the sign "Dangerous. Toxic substances."

1.6. Keep antifreeze away from sources of open flame.

1.7. Antifreeze is poured into the container no more than 90% of its capacity.

1.8. The processes of loading and unloading from large containers should be carried out using pumps, siphons.

1.9. It is forbidden:

a) allow untrained persons to work with antifreeze;

b) release antifreeze into containers that do not meet the above requirements;

c) pour the antifreeze through the hose by suction by mouth;

d) use antifreeze containers for transportation and storage of food products.

e) transport antifreeze together with people, animals, food.

f) drain antifreeze on the ground or down the drain;

2. Labor protection requirements before starting work

2.1. In a situation of a possible spill or splashing of antifreeze, prepare and put on protective equipment (overalls, rubber safety shoes, goggles, rubber gloves), make sure they are in good condition and fit.

2.2. Check availability of fire extinguishers. To extinguish antifreeze, it is allowed to use water, sand, felt mat, fire extinguishers.

2.3. Before pouring antifreeze, it is necessary to thoroughly clean the container from solid deposits, deposits and rust, rinse with an alkaline solution and steam it. There should be no residues of oil products in the container.

2.4. Before filling the engine cooling system with antifreeze, you must:

a) check for leaks in the cooling system (connecting hoses, radiator, water pump seals, etc.) and, if any, eliminate it,

b) Flush the cooling system with clean hot water.

3. Labor protection requirements during work

3.1. Filling the engine cooling system with antifreeze should be done only with the help of dishes specially designed for this purpose (buckets with a spout, funnels). Refueling utensils must be cleaned and rinsed as described in section 2.3 and labeled "for antifreeze only". When refueling, protect the antifreeze from getting oil products (gasoline, diesel fuel, etc.) into it, because. they lead to foaming of antifreeze during engine operation.

3.2. Antifreeze is poured into containers no more than 90% of their capacity in order to prevent their leakage from thermal expansion (since, for example, during engine operation (when heated), antifreeze expands more than water, which can lead to its leakage due to overflow of the cooling system ).

3.3. With the onset of warm weather, when the possibility of lowering the outside air temperature below 0 ° C is excluded, the antifreeze must be drained into a special container from the engine cooling system, filtered through a fabric filter and handed over to the warehouse for storage according to the act.

3.4. Do not smoke or eat while working with antifreeze.

3.5. Use antifreeze only for its intended purpose. Using it for other purposes (washing hands, containers, washing parts, etc.) is prohibited.

3.6. After each operation with antifreeze (receiving, dispensing, refueling the vehicle, quality control), wash hands thoroughly with soap and water.

4. Labor protection requirements in emergency situations

4.1. Since antifreeze contains ethylene glycol (EG), which has toxic properties, it is necessary:

a) if antifreeze spills or gets into open areas of the body, it must be washed off as soon as possible with plenty of water, neutralized with a 2-3% soda solution.

b) if coolant enters the stomach, it is necessary to induce vomiting as soon as possible in order to provide first aid to the victim, provide plenty of fluids, immediately call a doctor or send him to the nearest medical institution.

c) in case of contact with the skin and eyes, rinse with plenty of water.

Symptoms of poisoning. The initial period of poisoning (intoxication) resembles alcohol intoxication, the degree of which depends on the dose of poison taken into the body. Then the poisoned person may feel healthy, sleep often occurs. Later (in 1-2 days), the main symptoms of intoxication due to brain damage appear. . In the future, sleep-like stupor occurs, loss of consciousness, impaired cardiac activity and respiration, kidney and liver function, involuntary urination and defecation. Possible fatal outcome.

4.2. Provide assistance to the victim in case of poisoning, injury:

a) call an ambulance or take measures to transport the victim to the nearest medical facility;

b) inform the manager about the incident;

c) take urgent measures to prevent the impact of the traumatic factor on other persons;

d) prior to the beginning of the investigation of the accident, maintain the situation as it was at the time of the accident (if this does not threaten the life and health of other people and does not lead to an accident);

e) if it is impossible to save it, fix the current situation.

4.3. In case of poisoning, injury, contact a medical institution or call an ambulance through other members of the team, notify the immediate supervisor.

4.4. If a fire or fire is detected, you must:

a) immediately inform the fire department by calling _______.

b) immediately notify the personnel located in the area of ​​fire or smoke and the superior manager;

c) de-energize the equipment in the area of ​​fire or fire, leave the room, closing the door behind you;

d) if necessary, help the evacuation of people, if possible, take part in extinguishing the fire with the available fire extinguishing equipment (in compliance with safety requirements);

e) to evacuate equipment or other material values ​​only if these works are safe.

5. Labor protection requirements at the end of work

5.1. Seal antifreeze containers and transfer to designated storage areas as instructed.

5.2. Tidy up your workspace. Collect spilled antifreeze with sawdust and put it in a specialized container.

5.3. Clean overalls, footwear and personal protective equipment from contamination, put away in specially designated storage areas.

In case of contamination with antifreeze - thoroughly rinse rubber boots, rubber gloves with water; put the clothes in the laundry.

5.4. Wash hands thoroughly with warm water and soap.

5.5. Notify your immediate supervisor of any problems that arise during work.

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. ... >>

Random news from the Archive Superconducting DNA wires 28.01.2021 Physicists have figured out how to use DNA origami technology to produce superconducting nanowires of arbitrary shape and length. Due to this, it is possible that they can be used for the production of nanoelectronics. In recent years, scientists have identified many organic compounds that could replace silicon and other semiconductors in computer chips. Many of these compounds are already used in the development of LED and liquid crystal displays, sensors and various medical and scientific devices. At the same time, it turned out to be much more difficult to synthesize organic molecules that could conduct current and, due to this, replace metals. For example, scientists found one such substance only three years ago. It is an integrin protein that coats the surface of human cells. It turned out that its fragments can conduct current almost without loss. Researchers from Israel and the US have found that DNA molecules with metal nanoparticles attached to them can be used as scaffolds for complex composite superconductors. They wanted to combine a similar technology with DNA origami. This is the name of the method by which single strands of DNA can be used to assemble complex three-dimensional structures that can move, interact with environmental objects and solve various practical problems. Scientists have suggested that based on DNA origami, it is possible to create a technology thanks to which it will be possible to assemble nanowires of arbitrary shape, length and size. To do this, Bar-Ilan University physicist Lior Shani and his colleagues assembled several nanowires about 200 nm long and 25 nm thick. The scientists attached this structure to the surface of a special nanostructure, which consisted of a silicon substrate and two superconducting electrodes, and then studied the physical properties of the nanowire. The discovery can be applied to the use of superconductors in nanoelectronics and to the development of new scientific and industrial devices, including ultrasensitive magnetic field sensors, quantum signal amplifiers and various sensors.
