Special Firefighting Procedures: Use self-contained breathing apparatus and full protective gear, stay upwind, remove containers from fire area if safe
Explosion Data: May produce toxic or corrosive gases on heating or combustion
Additional Precautions: Cool exposed containers with water fog, prevent fire-fighting runoff from entering water sources or sewer
Accidental Release Measures
Personal Precautions: Evacuate area, ensure adequate ventilation, avoid breathing vapor, wear chemical-resistant gloves and safety goggles
Protective Equipment: Chemical splash goggles, gloves, respirator approved for toxic organic vapors, impervious clothing
Environmental Precautions: Prevent entry to sewers, soil, or waterways, contain spill with inert absorbent
Spill Cleanup Methods: Absorb in vermiculite, sand, or inert material, collect in chemical waste container, ventilate area
Decontamination: Wash spill site after material pickup
Large Spill Response: Evacuate non-essential personnel, dike area, contact emergency services, consult environmental authorities
Disposal: Dispose according to local, regional, national, and international regulations
Handling and Storage
Handling: Use only in a well-ventilated area, avoid all contact with skin and eyes, use fume hood for laboratory work, do not breathe vapor or mist
Safe Practices: Keep away from heat, open flames, sources of ignition, use spark-proof tools and explosion-proof equipment, keep containers tightly closed
Storage Conditions: Store in cool, dry, well-ventilated area, away from direct sunlight, incompatible materials, oxidizing agents, acids, bases
Container Requirements: Use only approved containers for halogenated solvents, keep tightly sealed when not in use
