PHYSICAL STATE; APPEARANCE:
YELLOW POWDER.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes. Reacts violently with hydrazine. Incompatible with combustible, organic or other readily oxidizable materials such as paper, wood, sulfur, aluminium, plastics.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: ppm; 0.0005 mg/m³ Intended change A2: as Cr (ACGIH 1991-1992).

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

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. The substance may cause effects on the kidneys and possibly liver , resulting in liver and kidney injury.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis or ulcers. Repeated or prolonged contact may cause skin sensitization. Lungs may be affected by repeated or prolonged exposure, and with some chromate exposures, nasal septim perforation has occurred. The substance may have effects on blood, liver and kidney and brain , resulting in changes in white and red blood cells, liver and kidney injury and neurovegetative diorders. This substance is possibly carcinogenic to humans.
