TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Water spray, foam, powder, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air. Slight explosion hazard in the form of vapour when exposed to flame.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
PREVENT DISPERSION OF DUST!

Inhalation Cough. Sore throat.
Local exhaust.
Fresh air, rest. Refer for medical attention.
Skin Redness.
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes Redness. Pain.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Cough.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: P2 filter respirator for harmful particles.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
ODOURLESS WHITE CRYSTALS.

PHYSICAL DANGERS:
Dust explosion possible if in powder or granular form, mixed with air.

CHEMICAL DANGERS:
The substance decomposes on heating producing highly toxic fumes of phosphorus oxides and phosphine. Reacts with strong acids and strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract.
