HazardClass: IRRITANT
Moderately toxic by intraperitoneal route. When heated to decomposition it emits toxic fumes of NOx. See also NITRO COMPOUNDS of AROMATIC HYDROCARBONS.
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Combustible solid. Containers may explode if exposed to fire. Risk of explosion if heated under confinement.
Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam.
Handling: Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes.
Storage: Store in a cool, dry place. Store in a tightly closed container.
