Advice for Firefighters: Wear full protective gear, self-contained breathing apparatus, avoid inhaling combustion byproducts, stay upwind of fire
Firefighting Procedures: Cool containers with water spray, move containers from fire area if safe.
Personal Precautions: Use appropriate personal protection, avoid contact with skin and eyes, ventilate area
Environmental Precautions: Prevent entry into waterways, drains, or soil
Clean-up Methods: Sweep up and place in suitable, sealable containers for disposal, wash spill site after material pickup is complete
Emergency Procedures: Evacuate unnecessary personnel, follow local regulations for reporting spills above threshold quantities.
Safe Handling: Keep containers tightly closed, use in well-ventilated spaces, avoid generating dust or aerosols, ground containers for transfer
Hygiene Measures: Wash hands after handling, do not eat, drink, or smoke during use, remove contaminated clothing
Storage Conditions: Store in a cool, dry area, away from incompatible substances like strong oxidizers or acids, keep container tightly sealed
Incompatible Materials: Strong oxidizing agents, strong acids, moisture
Special Storage Needs: Secondary containment recommended for large volumes, access control for laboratory or storage areas.
Exposure Limits: No established OSHA or ACGIH limits, minimize exposure by use of engineering controls
Ventilation: Use mechanical exhaust or fume hood to maintain concentrations below recommended exposure levels
Personal Protective Equipment: Chemical-resistant gloves (nitrile recommended), safety goggles, laboratory coat, dust mask or respirator if dust generation likely
Environmental Controls: Use spill containment or local capture where possible, avoid discharge to the environment, maintain clean workspace.
