Extinguishing oil and formaldehyde, what fire extinguisher is good?
The powder is characterized by high extinguishing efficiency, no conductivity, no corrosion, low toxicity, no melting, no decomposition, can be preserved for a long time, the disadvantage is not to prevent the resurgence of. The extinguishing agent is suitable for fighting petroleum products, paints, organic solvents and electrical fires.
[hazard] the vapor and air form an explosive mixture. In case of fire, high heat can cause combustion and explosion. React violently with oxidizing agents.Harmful combustion products] carbon monoxide, carbon dioxide.[method] water is sprayed out of the liquid to dilute it into a non flammable mixture and to protect the firemen with mist. Fire extinguishing agent: fog water, anti soluble foam, dry powder, carbon dioxide, sand.[emergency response] rapid evacuation of personnel from the contaminated areas to the safe areas, and quarantine, strictly restricting access. Cut off fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear acid proof working clothes. Get into the field from the windward side. Cut off the leak as much as possible. To prevent the inflow of sewage, flood channel limited space. Small amount of leakage: adsorption or absorption with sand or other non combustible material. Can also be washed with a large amount of water, washing water diluted into the waste water system. A large leak: construct a barrierpit to contain. Foam mulch to reduce steam damage. Spray water cools and dilute steam to protect personnel on the spot and dilute spills into non combustible materials. Transfer to tank car or special collector by pump, recycle or transport to waste disposal site.
