Highly flammable liquids: general safety requirements for use

Solvents, lighter fluid, oil, pesticides, paint, kerosene, propane, butane, gasoline, diesel, cleaning agents are all flammable liquids. These tools are used everywhere, especially the various types of fuel and cleaning products that everyone has in the house. When you move or work with any of them, you must follow the security rules.

If the profession involves working with combustible means, then it is necessary to know all the questions concerning the protection of one's life and others in case of fire. This article describes all the necessary requirements for flammable liquids.

General safety requirements

Any flammable liquid may pose a serious health risk or risk for a fire if misused. If the concentration of the vapor cloud reaches a certain temperature, the liquid illuminates. The substance itself, which is in a calm state, can not catch fire. Flammable liquids have a high flash point, flammable - low, so they are more dangerous to humans.

What should I do if I spill any money?

If the combustible substance has spilled, immediately it is necessary to open all the windows and to ventilate the room. Turn off all electrical equipment, as it is a source of sparks, which can lead to an explosion. If something has got on clothes - to remove, on a skin - to wash off water as soon as possible. If a large amount of combustible matter has spilled, it is advisable to evacuate all employees and call a fire department.

When the fire spreads, do not try to extinguish it with water, in the case of such liquids it will only aggravate the situation. The best fire extinguisher is. It should be stored near the work area.

Tips for working with materials

Before using any product, always read the label carefully. To make sure that you know how to properly use flammable and flammable liquids.

List of tips:

  1. You can not talk on the phone, listen to music or be distracted by anything else while working with combustible substances.

  2. Work with flammable liquids requires a well-ventilated room. As the vapors are unsafe, and harmful chemicals can enter the body through the respiratory tract. Many of them do not smell.

  3. Caution is the first rule. Take care that the product with which you work does not get on your skin or clothing.

  4. If there is a leak, tell the supervisor.

  5. Whenever you leave a room where a flammable liquid is stored, inspect it before closing the door.

  6. Never smoke cigarettes in the place where such substances are present. They should be stored away from open flames.

  7. Remember that there are many hidden sources of ignition, for example, in equipment.

  8. When using metal drums, hoses, pipes, make sure that they are grounded to avoid the accumulation of static charge, which can be a source of ignition.

  9. Make sure that all containers, taps, cans, pumps and other equipment that is used for storage are designed for the use of flammable liquids.

Avoid flammable substances

The best way to reduce the risk of fire is bypassing such means. If possible, you can replace it with another, less combustible substance. Look at the current view and determine if there are ways that you can perform the job more safely.

Take note of the following tips to help you work properly with flammable liquids.

First, it is necessary to pass special courses, in which the instructor will tell all the nuances of working with combustible substances.

Secondly, when it comes to safety, the health of others is very important. Observe the requirements for occupational safety and do not risk other people's lives.

What is the flash point and self-ignition?

The flash point of a flammable liquid is the minimum level at which the liquid emits vapors on the surface for ignition. The fluids themselves do not burn. A mixture of emitted vapors and air is burning.

Gasoline, with a flash-point of -43 ° C, is an inflammable liquid. Even at low temperatures, it gives enough vapor to form a combustible mixture with air.

Phenol is a flammable liquid. It has a flash-point from 79 ° C (175 ° F). Therefore, its level should exceed 79 ° C before it can ignite in the air.

The autoignition temperature of the most common liquids varies from 300 ° C (572 ° F) to 550 ° C (1022 ° F).

Limits of ignition of explosive substances

The lower limit of ignition is the proportion of vapors in the air above which a fire can not occur because there is not enough fuel. Pairs with a higher density than air tend to be more dangerous because they can flow around the floor and accumulate in low places.

The upper limit of ignition - the proportion of vapors in the air, when there is not enough air for ignition.

Flammable liquids are explosive, and these limitations give the range between the lowest and highest concentration of fumes in the air. That is, with the limits of ignition, you can determine which substance will burn and which can explode.

For example, the lower limit of explosive gasoline - 1.4%, and the upper limit - 7.6%. This means that this liquid can ignite when it is in the air at a level of 1, 4% to 7, 6%. The concentration of vapors below the explosive level is too low to ignite, more than 7.6% may cause an explosion.

The limits of ignition serve as guides in hot spots.

Why are such substances dangerous?

At normal room temperature, flammable liquids can emit a lot of vapor, forming combustible mixtures with air. As a result, they can pose a serious danger to the occurrence of a fire. Flammable liquids burn very quickly. They also emit a large amount of thick, black, poisonous smoke.

Flammable liquids at a temperature higher than their flash point can also lead to a serious fire.

Spraying of flammable and combustible liquids in the air leads to a fire if there is an ignition source. Vapors of substances are usually invisible. They are difficult to detect, unless special tools are used.

Flammable and flammable liquids are easily absorbed into wood, cloth and cardboard. Even after removing them from clothes or any other coatings, they can be dangerous, allocate harmful fumes.

What is the danger of such a liquid for the body?

Great harm such substances bring during a fire and explosion. They are dangerous to health. Flammable liquids can cause irreparable damage to the human body, depending on the specific material and mode of action:

  1. Inhalation of fumes.
  2. Contact with eyes or skin.
  3. Ingestion of liquid.

Most flammable liquids, flammable substances are dangerous to humans. Many of them are stored incorrectly and are incompatible chemical reactions, which can further damage.

Data on labels and containers should tell us about all the dangers for flammable substances that a person is working with.

For example, propanol (also known as isopropanol or isopropyl alcohol) is a colorless liquid with a pungent smell reminiscent of a mixture of ethanol and acetone. Vapors are heavier than air and can spread over long distances. High levels of vapors can cause headache, nausea, dizziness, drowsiness, impaired coordination of movements. The substance can also irritate the respiratory tract or eyes.

How to store substances in production areas, workshops, laboratories and similar workplaces

It should be recognized that for practical purposes, where liquids are used, it will most likely be necessary to store them in the workshop. Only a minimal amount of such substances can be placed in the work area, but even they should be used during the day or change the place. The actual figures for the storage time will depend on the work activity, organizational arrangements, fire risks in the workshop and the work area. Storage of flammable liquids in large quantities at home is prohibited. All responsibility will lie with the owners.

Containers for flammable liquids should be closed. They need to be placed in specially designated areas away from the immediate treatment area and do not jeopardize the workshop and work areas.

Flammable liquids should be stored separately from other hazardous substances that may increase the risk of fire or disrupt the integrity of the container or cabinet, for example, oxidants and corrosive materials.

What if the amount exceeds the maximum specified?

When recommended storage rates are exceeded, all factors should be evaluated. Please note the following:

  • Materials must be stored or processed in the work area;

  • Must take into account the size of the workshop and the number of people working there;

  • The amount of liquid processed in the workshop should not exceed the norms established by the enterprise;

  • The workshop must be equipped with good ventilation.

Must be an evacuation plan from the workshop, where they work with explosive substances.
