Flammability and ignitability

Figure 7-46 illustrates a typical relationship of limits of flammability and ignitibility for a methane air mixture. Note that energy required to ignite a flammable mixture (within its LET and UEL) varies with the composition, and that a 0.2 millijoule (mj) spark is inadequate to ignite even a stoichiometric mixture at atmospheric pressure at 26°C, while 1-mj spark can ignite any...

Caution. Potassium amide is flammable and ignites on contact with moisture. Residues are destroyed by cautious treatment with ethanol or isopropanol. Reactions with liquid ammonia must be done in a hood.
