What are the basic methods to prevent fire?

The basic methods to prevent fire include controlling combustible materials, controlling combustion-supporting materials, eliminating fire sources and preventing fire from spreading.

(1) Control combustible materials

The basic principle is to limit the basis of combustion or narrow the range of possible combustion. The specific method is:

1) Use incombustible or incombustible materials instead of flammable or combustible materials (such as using incombustible or incombustible materials as building structures and decoration materials);

2) Strengthen ventilation, reduce combustible gas and inflammable and explosive articles, and take measures such as separate storage and isolation;

3) Impregnating combustible materials with fire retardant coating to change their combustion performance;

4) For articles that may burn or explode due to interaction, measures such as separate storage and isolation should be taken.

(2) Controlling combustion-supporting materials

Its principle is to limit the combustion-supporting conditions of combustion, and the specific method is:

1) Rooms, containers and equipment containing flammable and explosive substances shall be sealed, and production using flammable and explosive substances shall be carried out in closed equipment pipelines;

2) filling inert gas for the production with abnormal danger (such as acetylene filling with nitrogen, methanol oxidation, TNT ball milling);

3) Store in isolation from air, such as carbon disulfide and phosphorus in water, and metal potassium and sodium in kerosene.

(3) Eliminate the ignition source

Its principle is to eliminate or control the ignition source of combustion. The specific method is:

1) Smoking, naked flame and spikes are prohibited in dangerous places;

2) Adopt explosion-proof electrical equipment and install lightning rod and grounding wire;

3) During baking, boiling and heat treatment, the temperature should be strictly controlled to not exceed the self-ignition point of combustible substances;

4) Always lubricate the machine bearings to prevent friction from generating high temperature;

5) Electrical equipment shall be equipped with safety devices to prevent fire caused by short circuit or overload of wires;

6) The warehouse storing flammable chemicals should be protected from light;

7) When transporting flammable chemicals, iron handling tools should be wrapped with rubber or lined with copper and aluminum sheets;

8) Install fire-proof caps or flame arresters for smoke exhaust systems such as automobiles.

(4) stop the fire from spreading

Its principle is not to form new combustion conditions, to prevent or limit the expansion of the fire. The specific method is:

1) Keep sufficient fire separation between buildings, storage tanks and storage yards, set up firewalls and divide fire zones;

2) Install flame arrester and water seal on combustible gas pipeline;

3) Set pressure relief doors and windows, light roofs and light walls. Workshops that can form explosive media (combustible gas, combustible steam and dust);

4) Install explosion-proof membrane and safety valve on the pressure vessel.

fire precautions

1. Carry out regular fire prevention publicity and education.

2. Implement fire prevention inspection to find and eliminate fire hazards.

A. the conclusion and implementation of fire laws, regulations and conventions;

B. staffing of fire control organizations;

C. use and maintenance of fire fighting equipment.

D. elimination and rectification of fire hazards.

E. Whether all kinds of dangerous goods conform to fire safety, whether there are fire control measures in production, use and storage, and the hidden dangers found in fire inspection should be solved in time.

3. Improve and thoroughly implement the fire prevention system. There are four main fire prevention systems: a. fire prevention responsibility system step by step;

B. post responsibility system for fire prevention;

C. fire management system;

D. fire safety operation procedures.

4. Maintain the fire fighting equipment in the property.

5. Strengthen key prevention, prevent major fires, and ensure fire safety in key parts. The focus is on the parts with high risk, large fire release loss and heavy casualties.
