Chemical Properties

Chromic acetate is a gray-green powder or blue-green pasty mass

Uses

Textile mordant, tanning, polymerization and oxidation catalyst, emulsion hardener.

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. Chromic acetate is used in tanning and in textile dyeing.

Air & Water Reactions

Water soluble.

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.

Hazard

Toxic by ingestion.

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.

Flammability and Explosibility

Non flammable

Safety Profile

Questionable carcinogen with experimental tumorigenic data. Moderately toxic by intravenous route. Human mutation data reported. See also CHROMIUM COMPOUNDS. When heated to decomposition it emits acrid smoke and irritating fumes.

Potential Exposure

Chromic acetate is used to fix certain textile dyes; to harden photographic emulsions in tanning, and as a catalyst

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention.

storage

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with Chromicacetate you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area. A regulated, marked area should be established where Chromic acetate is handled, used, or stored. Aregulated, marked area should be established where thischemical is handled, used, or stored in compliance withOSHA Standard 1910.1045.

Shipping

UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Incompatibilities

Contact with strong oxidizers may cause fire and explosion hazard

Waste Disposal

Dilute and stir in excess soda ash. Let stand, neutralize liquid and flush to sewer. Dispose of sludge in landfill.
