CHEMICAL DANGERS:


OCCUPATIONAL EXPOSURE LIMITS:
TLV (as Cr): 0.01 mg/m3 (as TWA) A1 (ACGIH 1999).
MAK: sensitization of skin (Sh);
Carcinogen category: 1
(DFG 2008).


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 .

EFFECTS OF SHORT-TERM EXPOSURE:
Inhalation of dust may cause irritation.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma. Repeated or prolonged exposure may cause nasal ulceration. This substance is carcinogenic to humans.

Solubility in water:
none

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms.

N O T E S

The term zinc chromate is also used to refer to a wide range of commercial zinc and zinc potassium chromates. It has several CAS numbers. Depending on the degree of exposure, periodic medical examination is indicated. Pigment Yellow 36 and Buttercup Yellow are trade names. Do NOT take working clothes home.
