4.3 Spills and Disposal
Spills
Wear self-contained breathing apparatus and full protective clothing. Keep combustibles (wood, paper, oil etc) away from spilled
material.
Disposal
Dispose of in accordance with Local, State and Federal regulations.
4.4 FIRE AND EXPLOSION HAZARD
Fire / Explosion
Practically all nitrates are powerful oxidising agents. Fire fighters should wear protective equipment with self-contained breathing
apparatus and full face- piece operated in positive pressure mode. Move containers from fire area if this can be done without risk.
Use water to keep fire-exposed containers cool. Incompatible with oxidising materials, such as organic compounds and reducing
agents. Hazardous decomposition products include nitrous and nitric oxides. The material is insensitive to impact, but may
explode when exposed to excessive heat or flame or by chemical reaction with oxidisable material. Closed containers exposed to
heat may explode.
Extinguishing Media
Use water to extinguish fires.
