7.1.2 Hazard Classes and Categories

Carcinogenicity - category 1A

Specific target organ toxicity (repeated exposure) - category 2

Skin sensitisation - category 1

Acute toxicity (ingestion) - category 4

Acute toxicity (inhalation) - category 3

7.1.3 Hazards Summary

CrVI compounds are irritants, sensitizers, and may be corrosive to the skin. CrVI compounds are respiratory tract irritants and may cause pulmonary sensitization. CrVI may cause acute tubular necrosis and liver injury. [ATSDR Case Studies] May cause irritation; [MSDSonline] See Chromium and linked occupational diseases.

8 Toxicity

8.1 Toxicological Information

8.1.1 Adverse Effects

Occupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation.

Nephrotoxin - The chemical is potentially toxic to the kidneys in the occupational setting.

Dermatotoxin - Skin burns.

Skin Sensitizer - An agent that can induce an allergic reaction in the skin.

Asthma - Reversible bronchoconstriction (narrowing of bronchioles) initiated by the inhalation of irritating or allergenic agents.

IARC Carcinogen - Class 1: International Agency for Research on Cancer classifies chemicals as established human carcinogens.

NTP Carcinogen - Known to be a human carcinogen.

ACGIH Carcinogen - Confirmed Human.
