What are the basic measures to prevent fire?

All fire prevention measures are to prevent the conditions of combustion and prevent the combination and interaction of combustion conditions. According to the principle of material combustion, the basic measures of fire prevention are:

1. Control of combustible materials. Combustibles are the material basis of combustion process, so the use of combustibles should be careful. When selecting materials, try to use refractory or non combustible materials instead of combustible materials, such as using cement instead of wood to build houses, and using fire retardant paint to dip combustible materials to improve fire resistance; For the workshop with fire and explosion risk, exhaust or ventilation method is adopted to reduce the concentration of combustible gas, steam and dust in the air; All items that can interact with each other should be stored separately2. Keep out the air. The production process using inflammable and explosive materials should be carried out in sealed equipment; For production with abnormal risk, inert gas can be filled for protection; Some dangerous chemicals are stored in the air, such as sodium in kerosene, yellow phosphorus in water, carbon disulfide in water< 3. Remove the fire source. For example, measures such as isolating fire source, controlling temperature, grounding, lightning protection, installing explosion-proof lamp, shielding sunlight, etc. shall be taken to prevent combustibles from catching fire in case of open fire or rising temperature< 4. Prevent the spread of fire and explosion wave. 1n order to prevent the spread of fire and explosion wave, it is necessary to prevent the formation of new combustion conditions, so as to prevent the expansion of fire and reduce fire losses. The specific measures are: installing flame arrester and safety water seal on combustible gas pipeline; The smoke exhaust and exhaust systems of locomotives, ships, automobiles and bulldozers shall wear fire caps; 1nstall explosion-proof membrane and safety valve on pressure vessel equipment; Leave fire prevention space between buildings, build fire wall, etc
