Specific Hazards: May release carbon oxides under combustion; dust may form explosive mixtures in air
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective clothing
Special Procedures: Use water spray to cool containers, avoid inhalation of smoke or vapors, prevent runoff from entering drains or waterways
Personal Precautions: Wear dust mask, chemical goggles, and gloves; avoid breathing dust; ensure adequate ventilation
Spill Cleanup Methods: Sweep or shovel spillage into suitable containers for disposal, use non-sparking tools, wipe area with damp cloth or wash with water to fully remove residues
Environmental Precautions: Avoid release to the environment, prevent spillage from reaching drains or waterways
Handling: Avoid creating or breathing dust; use in well-ventilated areas; wear appropriate personal protective equipment; wash hands and exposed skin after handling
Storage: Keep containers tightly closed, dry, and in a cool, ventilated place away from sources of ignition and incompatible substances such as strong oxidizers and bases; store only in original or approved containers; prevent moisture ingress to avoid caking or degradation
Engineering Controls: Use local exhaust ventilation to reduce airborne concentrations; keep eye wash stations and emergency showers accessible
Respiratory Protection: Wear NIOSH-approved dust respirator if dust generation is likely
Eye Protection: Use chemical safety goggles or face shield
Hand Protection: Wear chemical-resistant gloves (such as nitrile or PVC)
Skin and Body Protection: Wear long sleeves and long pants to prevent skin exposure; use lab coat or suitable apron as needed
Hygiene Measures: Do not eat, drink, or smoke when using this product; wash hands before breaks and after handling
