Unusual Fire & Explosion Hazards: Decomposition above 200潞F liberates toxic phosphine
fumes. Contact with strong alkalies will result in violent
reactions evolving steam. Contact with metal salts of
sulfides and sulfites may result toxic fumes.
Extinguishing Media: Does not burn or support combustion. Use appropriate
media for surrounding fire.
Special Firefighting Procedures: Wear positive pressure, self-contained breathing
apparatus and complete personal protective equipment.
Cool storage drums and exposed structures with water
spray. Avoid smoke inhalation. Contain any liquid
runoff.
SECTION 6. SPILLS AND LEAKS
Containment: Prevent product spillage from entering drinking water supplies or streams.
Clean Up: Absorb onto absorbent material and package for disposal at an appropriate waste disposal facility.
Evacuation: Not necessary.
SECTION 7. STORAGE AND HANDLING

etc.
Work/Hygienic Practices: Harmful if swallowed. Causes eye and skin irritation. In case of contact, immediately
flush eyes or skin with plenty of water and contact a physician.
SECTION 8. PERSONAL PROTECTIVE EQUIPMENT
Eyes: Chemical dust/splash goggles or full-face shield to prevent eye contact. As a general rule, do not
wear contact lenses when handling.
Skin: Impervious gloves and clothes.
Respiratory: Not normally needed. If use generates an aerosol mist or respiratory irritation, use NIOSH-approved
dust/mist respirator (such as 3M #8710).
