Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam
Unsuitable Extinguishing Media: Water (may spread fire)
Specific Hazards: Releases toxic fumes (phosphine, oxides of phosphorus) under fire conditions, vapors may form explosive mixtures with air
Advice for Firefighters: Wear self-contained breathing apparatus and full protective gear, avoid inhalation of fumes, use water spray to cool containers
Personal Precautions: Wear protective equipment, avoid contact with skin, eyes, and clothing, ventilate area, remove all sources of ignition
Environmental Precautions: Prevent further leakage or spillage, avoid entering drains, sewers, or waterways
Methods for Cleanup: Contain and collect spillage with inert absorbent material (sand, earth, vermiculite), place in chemical waste container, clean with non-flammable, non-reactive cleaning agent
Safe Handling: Avoid inhalation of vapors, minimize exposure with appropriate ventilation, use spark-proof tools, wear recommended protective equipment
Storage Conditions: Store in cool, dry, well-ventilated area away from incompatible substances, keep container tightly closed, ground and bond containers, protect from direct sunlight or any ignition source
Incompatibles: Oxidizers, strong acids, halogens, air, moisture
Engineering Controls: Use fume hood or local exhaust, maintain airborne concentrations below recommended limits (if set by workplace regulations)
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, lab coat or chemical-resistant apron, appropriate respirator if airborne exposure is possible
Hygiene Measures: Remove contaminated clothing, wash hands before eating or drinking, do not smoke or consume food in handling area
