General Description

A grayish green to bluish green powder. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used in tanning and in textile dyeing.

Hazards

Reactivity Alerts

none

Air & Water Reactions

Water soluble.

Fire Hazard

No information available.

Health Hazard

INHALATION: Irritating. It can produce ulcerations in the respiratory system, perforation of the nasal septum, pneumonitis and bronchial carcinoma. EYES: Irritation. SKIN: May cause dermatitis to exposed skin. Can produce ulcerations and sensitizing reactions. (USCG, 1999)

Reactivity Profile

CHROMIC ACETATE gives aqueous solutions that are basic (neutralize acids). These neutralizations generate only a little heat. Neither a strong reducing agent nor oxidizing agent, but can serve as both.

Belongs to the Following Reactive Group(s)
