PHYSICAL STATE; APPEARANCE:
FINE, WHITE, ODOURLESS CRYSTALLINE POWDER (MONOHYDRATE). LIQUEFIES ON LOSS OF ITS WATER OF CRYSTALLIZATION. TURNS DARK ON EXPOSURE TO LIGHT.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes including phosphorus oxides and nitrogen oxides .

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK 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 when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the blood, bladder, central nervous system and heart.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood, bladder, lungs and bone marrow , resulting in leucopenia, cystitis, pulmonary fibrosis. This substance is carcinogenic to humans. May cause heritable genetic damage in humans. Does cause serious reproductive toxicity in humans.

PHYSICAL
PROPERTIES

Melting point: (monohydrate) 41-45°C
