Chimney bombs are zip-lock bags or other small bags filled with ABC dry chemical powder. Chimney bombs are used by fire service personnel to help extinguish chimney fires. Creosote, which is the by-product of the incomplete burning of wood (typically due to chronic combustion-air insufficiency), is extinguished by the chain reaction caused by ...
Ammonium dihydrogen phosphate (ADP), also known as monoammonium phosphate (MAP) [5] is a chemical compound with the chemical formula (NH 4)(H 2 PO 4). ADP is a major ingredient of agricultural fertilizers [6] and dry chemical fire extinguishers. It also has significant uses in optics [7] and electronics. [8]
Several modern "ball" or grenade-style extinguishers are available on the market. The modern version of the ball is a hard foam shell, wrapped in fuses that lead to a small black powder charge within. The ball bursts shortly after contact with flame, dispersing a cloud of ABC dry chemical powder which extinguishes the fire.

If local exhaust ventilation or enclosure is not used, respirators are necessary. Wear protective work clothing and change clothes and wash thoroughly immediately after exposure to ammonium bicarbonate. [10]
Purple-K, also known as PKP, is a dry-chemical fire suppression agent used in some dry chemical fire extinguishers.
