Poison by subcutaneous and intravenous routes. Moderately toxic by ingestion. Combustible when exposed to heat or flame. Moderately explosive in the form of vapor when exposed to flame. Can react with oxidizing materials. To fight fire, use water, CO2, dry chemical. Incompatible with diazonium salts. When heated to decomposition it emits highly toxic fumes of K2O and SOx.
1. Fire Fighting Measures
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam.
2. Handling and Storage
Handling: Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. Avoid ingestion and inhalation.
Storage: Store in a cool, dry place. Store in a tightly closed container.
