Fire-Fighting Measures

Suitable extinguishing media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable extinguishing media: High volume water jets
Specific hazards: Potential formation of toxic and corrosive gases on heating or combustion (hydrogen fluoride, sulfur oxides, nitrogen oxides)
Protective equipment: Firefighters must use self-contained breathing apparatus and full protective gear
Special fire-fighting procedures: Evacuate area, contain runoff from firefighting to prevent environmental contamination, cool containers exposed to fire
Fire residues disposal: Dispose per local regulations regarding hazardous chemicals

Accidental Release Measures

Personal precautions: Avoid contact with eyes and skin, ventilate area, use personal protective equipment such as gloves and goggles
Environmental precautions: Prevent leakage to drains and surface water, avoid soil contamination, notify authorities if significant spillage occurs
Cleanup methods: Absorb with inert materials like sand, clay, or commercial absorbents, collect in closed containers for disposal, decontaminate area with soap and water
Reference to other sections: See exposure controls and disposal considerations for further guidance
Inadequate containment: Use diking to contain liquid, prevent runoff to water bodies

Handling and Storage
