Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and chemical protective clothing
Fire/Explosion Risk: Product may form slippery layers on surfaces and increase fall hazard, not known to be highly flammable
Personal Precautions: Use personal protective equipment including gloves, eyewear, respirator if powder is airborne
Methods for Cleanup: Absorb liquid spills with inert material like sand or earth, place in container for disposal, sweep or vacuum powder without generating dust
Environmental Precautions: Prevent entry into drains, watercourses, or soil to minimize risk of aquatic pollution
Spill Response: Wash remaining traces with water, ventilate area, avoid contamination of drinking water sources
Safe Handling: Avoid direct contact with eyes, skin, or clothing, handle with appropriate PPE, wash hands after use
Technical Measures: Use in areas with local exhaust ventilation, avoid dust formation, keep containers tightly closed when not in use
Storage Conditions: Store in a cool, dry, well-ventilated area away from strong acids and oxidizers, recommended temperature below 30°C
Incompatible Materials: Avoid contact with strong oxidizing agents, strong acids may cause breakdown of the surfactant
