Protective Equipment for Firefighters: Full protective gear, self-contained breathing apparatus
Special Procedures: Cool fire-exposed containers with water fog, contain runoff to prevent environmental contamination
Personal Precautions: Evacuate area, avoid inhalation of vapors, use personal protective equipment
Environmental Precautions: Prevent entry into sewers, drains, waterways; contain runoff
Methods for Clean-Up: Absorb with inert material such as sand or earth, use non-sparking tools, ventilate area
Decontamination: Wash contaminated area with plenty of water after disposal of absorbed material
Handling: Ensure good ventilation, avoid contact with eyes, skin, and clothing, keep away from incompatible substances such as strong oxidizers or alkalis, use spark-proof tools
Storage: Store away from heat sources and direct sunlight, keep container tightly closed in a cool, well-ventilated area, segregate from oxidizing agents, label storage zone with hazard signage, prevent accidental water addition to concentrated product
Engineering Controls: Use local exhaust ventilation to keep airborne levels below exposure limits, safety shower and eyewash station should be accessible
