Special Protective Equipment: Full body suit with fire-resistant clothing, self-contained breathing apparatus, remote firefighting techniques strongly recommended
Fire/Explosion Precautions: Withdraw immediately if fire intensifies, use unmanned monitors or hoses, avoid shock or friction, evacuate surrounding area
Other Information: Contaminated extinguishing water may be hazardous to environment, prevent runoff into drains or waterways
Personal Precautions: Clear area of all non-essential personnel, prevent unnecessary movement to avoid friction or impact, use non-sparking tools, initiate explosion-protection procedures, wear chemical protective suit and respirator
Environmental Precautions: Prevent entry to sewers, drains, surface and groundwater, contain spills using inert, non-combustible absorbent (e.g., vermiculite), notify authorities in case of significant release
Containment/Cleanup: Carefully sweep up using scoop, minimize dust, place in explosion-safe container for disposal, decontaminate area thoroughly, ventilate and inspect with proper detection equipment
Safe Handling: Use away from sources of heat, sparks, or open flame, ground and bond containers, open containers carefully in fume hood, don’t use incompatible materials or shoddy tools, keep smallest practical quantities
Protective Measures: Always use explosion-shielded workspace, avoid any rough handling or dropping, label containers with clear warning signage
Storage Recommendations: Store in tightly closed, compatible containers within dedicated secure magazine approved for explosives, keep in cool, dry, well-ventilated space under lock and key
Incompatibilities: Strong reducing agents, acids, bases, metals, combustibles, sources of static electricity, flammable materials
Temperature Requirements: Keep below 25°C, avoid direct sunlight and fluctuations, humidity controlled to prevent hydrolysis or condensation
Segregation: Store separately from oxidizers, organic acids, food, and feedstuffs
Exposure Limits: No established OSHA, ACGIH, or NIOSH limits; handle as highly toxic and sensitize at any exposure
Engineering Controls: Employ chemical fume hood with explosion-proof equipment, local exhaust ventilation, maintain clean workspace with explosion suppression systems
Personal Protection: Full chemical-resistant suit (Tyvek/ChemMax or equivalent), heavy nitrile or neoprene gloves, integrated splash goggles, face shield, approved air-purifying respirator or supplied-air system
Work Hygiene: Remove contaminated clothing immediately, practice strict hand hygiene, never eat, drink, or smoke in work area, keep eyewash and safety shower nearby
Monitoring: Use continuous air monitoring if possible, regular health checks for exposed personnel, strict supervision of all work
