Ignitability Characteristic of substances that are liquids, the vapors of which are likely to ignite in the presence of ignition sources nonliquids that may catch fire from friction or contact with water and that bum vigorously or persistently ignitable compressed gases and oxidizers... [Pg.384]

Firedamp Explosions. Firedamp may be ignited by die flame from an explosive (Ref 2) or detonator (Ref 4), by jets of compressed air (Ref 5), and by friction (Ref 6). Ignition of firedamp by expls is avoided by use of especially formulated expls called Permis-sibles. These expls usually contain inorg salts that absorb heat and thus cool the deton gases. The cooled gases in turn help to choke the flame of the firedamp (Ref 8). The salt may also inhibit chain propagation... [Pg.411]

Other Ignition Sources Hazardous classification of locations for electrical installations is covered in Articles 500-504 of the National Electrical Code (NEC) (NFPA 70). Proper hazardous classification is essential for safety and for prevention of explosion and fire losses. Class 1 in the NEC is for vapors and gases in the United States, in brief. Division 1 of Class 1 includes those locations where flammable concentrations exist continuously or frequently. Division 2 includes locations where flammable concentrations may exist only in case of accidental escape of vapors or gases, or in case of abnormal operation of equipment. Static electricity, which causes fires and explosions with flammable vapors and gases, is covered later in Sec. 26. Cither ignition sources include friction and impact plus rubbing with rubbing... [Pg.2072]
