Special Fire Hazards: Vapors may travel along surfaces to distant ignition sources, decomposition may produce irritating and toxic gases including hydrogen chloride and phosgene
Firefighter Precautions: Use self-contained breathing apparatus and full protective gear, keep run-off water out of sewers and drains
Explosion Risk: Mixture with air may form explosive vapors
Personal Precautions: Evacuate non-essential personnel, ventilate area, wear chemical-resistant clothing, goggles, proper gloves, and suitable respiratory protection
Environmental Precautions: Prevent further leakage or spillage if safe, block entry into waterways, sewers, basements, or confined areas
Containment Methods: Dike and absorb with inert material such as vermiculite or sand, do not use combustible absorbents
Cleanup Procedures: Collect in closed, labeled containers for disposal, decontaminate spill site following appropriate chemical protocols
Handling Precautions: Avoid all contact with skin and eyes, operate in fume hood or well-ventilated area, keep away from sources of ignition, ground and bond all containers, avoid inhaling mists or vapors
Safe Storage Conditions: Store in tightly closed, properly labeled containers, away from incompatible substances such as strong oxidizers, acids, and bases, keep containers in a cool, dry, and well-ventilated location
Storage Incompatibilities: Avoid storage near sources of heat or direct sunlight, prevent accumulation of static charges, use corrosion-resistant shelving
Specific Storage Requirements: Use explosion-proof refrigerators or cabinets where required, store below 25°C for optimal stability, segregate from foodstuffs
Occupational Exposure Limits: No OSHA or ACGIH exposure limits established; minimize exposure by good industrial hygiene practices
Engineering Controls: Fume hoods, mechanical exhaust, and local ventilation systems that capture vapors at source
Personal Protective Equipment (PPE): Chemical safety goggles, face shield if splash may occur, nitrile, butyl, or neoprene gloves, impervious laboratory coat or apron, respiratory protection (NIOSH-approved organic vapor respirator) for non-ventilated areas
