Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, CO₂, water spray, or foam as appropriate for adjacent materials
Unsuitable Extinguishing Media: None known
Hazardous Combustion Products: At high temperatures, may produce zinc and tin oxides
Special Protective Equipment: Wear NIOSH-approved self-contained breathing apparatus and full protective gear
Fire Hazards: Product itself does not burn, mainly an irritant
Firefighter Advice: Prevent dust accumulation, cool containers exposed to fire with water spray, avoid inhalation of fumes generated by other burning materials

Accidental Release Measures

Personal Precautions: Avoid dust generation, wear respiratory protection, gloves, and safety goggles
Environmental Precautions: Prevent entry to surface waters and drains, sweep up to avoid spreading dust
Cleanup Methods: Use industrial vacuum or dampen solid before collection, place into labeled waste container for proper disposal
Spill Response: Notify safety supervisor, restrict area to only necessary personnel
Decontamination: Wash area with abundant water after removal, dispose of cleaning materials with solid waste

Handling and Storage

Safe Handling Practices: Avoid generation of airborne dust, use only with adequate ventilation, wash hands after use, do not eat, drink, or smoke while handling
Protective Equipment: Wear protective gloves and eye protection, use dust-respirator if dusty
Storage Conditions: Keep container tightly closed, store in a dry, cool, and well-ventilated area
Incompatibilities: Store away from acids, strong oxidizers, and food products
Other Restrictions: Keep away from sources of ignition, avoid rough handling that might create dust

Exposure Controls and Personal Protection
