Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Extinguishing Media: Direct water jet may spread burning material
Special Hazards Arising from Chemical: Combustion may produce toxic gases such as nitrogen oxides, sulfur oxides, carbon oxides, hydrogen chloride
Protective Equipment for Fire-Fighters: Wear self-contained breathing apparatus and full protective clothing
Fire-Fighting Procedures: Use water spray to cool fire-exposed containers, avoid inhaling combustion products, contain runoff to prevent environmental impact
Personal Precautions: Isolate spill area, wear appropriate respiratory protection, gloves, and chemical safety goggles
Environmental Precautions: Prevent further leakage or spillage if safe to do so, avoid discharge into drains, water courses, or onto the ground
Methods for Containment and Cleanup: Sweep up without creating dust, place in suitable labeled container for disposal, ventilate affected area, wash spill area with water and detergent, ensure all cleaning materials are safely discarded
Additional Measures: Monitor air quality if large amounts released, notify local authorities if significant environmental contamination occurs
Precautions for Safe Handling: Handle away from sources of ignition, minimize dust generation and accumulation, avoid skin and eye contact, do not ingest or inhale
Safe Storage Conditions: Store in a cool, dry, well-ventilated area, keep container tightly closed when not in use, segregate from food and incompatible chemicals such as strong oxidizers
Additional Recommendations: Use only in areas with adequate ventilation, maintain good industrial hygiene practices, regularly inspect storage containers for integrity
Control Parameters: No established occupational exposure limits, recommend minimizing exposure to dust
Engineering Controls: Use local exhaust ventilation to maintain airborne levels below recommended limits, use enclosures or process isolation when feasible
Personal Protective Equipment: Protective gloves (nitrile or neoprene), chemical safety goggles or face shield, lab coat or apron, approved respiratory protection for dusty operations
