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 STORAGE PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place.
Separated from oxidants , acids. Keep in a well-ventilated room.

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.
MAK: 5 mg/m (Inhalable fraction);
Peak limitation category: II(2);
sensitization of skin (Sh);
Pregnancy risk group: C
(DFG 2009).


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.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL
PROPERTIES
Boiling point: 377C
Melting point: 80C
Relative density (water = 1): 1.1
Solubility in water:
none
Relative vapour density (air = 1): 9.0
Flash point: 180C o.c.
ENVIRONMENTAL
DATA

N O T E S
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
NFPA Code: H 0; F 1; R 0;
