First, control combustibles. Combustibles are the material basis of the combustion process, so use caution when using combustibles. When selecting materials, replace combustible materials with non-flammable or non-combustible materials as much as possible. For example, use cement instead of wood to build houses, and dip fuel lacquer with fireproof paint to improve fire resistance; use fire ventilation or ventilation for buildings with fire and explosion hazards. Methods to reduce the concentration of combustible gases, vapors, and dust in the air; any items that can interact with each other should be stored separately.
Second, isolate the air. The production process using flammable and explosive materials should be carried out in sealed equipment; for the production of abnormal danger, inert gas protection can be filled; and some chemical dangerous goods such as metallic sodium stored in kerosene can be isolated from the air. Stored in water, carbon disulfide closed storage with water.
Third, remove the fire source. Such measures as isolation of fire sources, temperature control, grounding, lightning protection, installation of explosion-proof lights, and shielding of sunlight shall be taken to prevent flammable substances from catching fire or from rising temperatures and causing fire.
Fourth, stop the spread of fire and explosion waves. In order to prevent the spread of fire and explosion waves, it is necessary to prevent the formation of new combustion conditions so as to prevent the expansion of fire and reduce the loss of fire. Concrete measures include installing flame arresters and safety water seals on combustible gas pipelines; wearing fire caps on exhaust and exhaust systems of locomotives, ships, automobiles, bulldozers; installing explosion-proof membranes and safety valves on pressure vessel equipment; Spacing between fire walls, building firewalls, etc.
What are the basic measures for preventing fire?
All fire prevention measures are designed to prevent the occurrence of burning conditions and to prevent the burning conditions from combining and interacting with each other. According to the principle of material combustion, the basic measures for fire prevention are:
