• chemically stable • reacts in fire to create hydrogen combustable • Ammonia will combine with mercury to form a fulminate which is an unstable explosive compound • does not combust itself
firefighting
BA GTS Thermal gloves avoid contact cool heated containers stop leak small spill cosider evac/ stay indoors windows shut large spill contain gas will disperse DO NOT allow in water course fine spray, fog,CO2, Powder Pulmonary oedema may occur 48hrs later MDT
