PHYSICAL STATE; APPEARANCE:
ODOURLESS WHITE CRYSTALS OR CRYSTALLINE POWDER.

PHYSICAL DANGERS:


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

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the central nervous system and cardiovascular system , resulting in insomnia, excitement, tachycardia, polyuria.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Animal tests show that this substance possibly causes toxic effects upon human reproduction.
