For more information, go to [ Ссылка ] . This is clipped from the 1948 film The Chemistry of Fire from the US War Department. The film describes chemical processes occurring during combustion, using many interesting demonstrations: describes the vaporization of burning articles, demonstrates flash and fire points of various substances, describes how phosphorus burns, oxygen requirements for burning, the operation of an oxy-acetylene torch, and the perils of gasoline vapor, explains ignition temperatures, shows fires caused by static electricity, combustion, bomb explosions, shrapnel piercing fuel lines, and ignition of paint and bedding, describes the use of carbon dioxide, steam, and foam to extinguish fires, fires are extinguished by high-pressure streams of water, by immersion in water, and by flooding.
