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.
