Firefighting Instructions: Keep containers cool with spray, avoid inhaling vapors or dust, suppress vapors using water spray if spill occurs during fire
Personal Precautions: Put on chemical-resistant gloves, safety goggles, and dust mask before beginning cleanup, ensure adequate ventilation in area
Environmental Precautions: Prevent chemical entry into drains or water sources, dike spills using absorbent inert material
Cleanup Methods: Scoop up and containerize using spark-proof tools, avoid raising dust, wash spill site with plenty of water after pickup
Additional Advice: Dispose of contaminated cleanup materials in accordance with disposal guidelines, report major spills to responsible authorities immediately
Handling: Use only in well-ventilated work spaces, avoid breathing vapors or contact with skin or eyes, put on approved PPE before handling, clean protective gear regularly and wash hands after work
Storage: Store chemical in a tightly closed, corrosion-resistant container away from sunlight, incompatible substances (oxidizers, strong acids), moisture, and sources of ignition, keep out of reach of children, clearly label all containers
Additional Handling Notes: Use explosion-proof electrical equipment in handling areas, do not eat, drink, or smoke in chemical work zones
Occupational Exposure Limits: No established OSHA/ACGIH limits for this compound, work should proceed as though exposure risk is present
Engineering Controls: Install local exhaust ventilation, use fume hood for all open transfers
Personal Protection: Use nitrile gloves, chemical-resistant goggles, protective lab coat, dust respirator or half-mask with organic vapor cartridge, use closed working systems if practical
