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.
Powder, water spray, foam, 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
    Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P2 filter respirator for harmful particles).
    		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 phosphorous oxides and phosphine. Reacts with strong acids and strong oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     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 20░C 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: 377░C
    Melting point: 80░C
    Relative density (water = 1): 1.1
    		 Solubility in water: none
    Relative vapour density (air = 1): 9.0
    Flash point: 180░C 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.
