**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Toxic if swallowed. Causes severe burns. May cause sensitization by
skin contact. Contact with combustible material may cause fire. May
cause cancer by inhalation. Very toxic to aquatic organisms, may
cause long-term adverse effects in the aquatic environment.

Potential Health Effects
Eye:
May cause irreversible eye injury. Contact with eyes may cause
severe irritation, and possible eye burns.
Skin:
May cause skin sensitization, an allergic reaction, which becomes
evident upon re-exposure to this material. May cause irritation with
burning pain, itching and redness. May cause deep, penetrating ulcers
of the skin. May be absorbed through damaged or abraded skin in
harmful amounts. Chronic exposure to water insoluble hexavalent
chromium compounds has been shown to be associated with lung cancer
and gastrointestinal tract tumors.
Ingestion:
Harmful if swallowed. May cause severe gastrointestinal tract
irritation with nausea, vomiting and possible burns. May cause liver
and kidney damage.
Inhalation:
May cause irritation of the respiratory tract with burning pain in
the nose and throat, coughing, wheezing, shortness of breath and
pulmonary edema. May cause asthmatic attacks due to allergic
sensitization of the respiratory tract.
Chronic:
Prolonged or repeated inhalation may cause nosebleeds, nasal
congestion, erosion of the teeth, perforation of the nasal septum,
chest pain and bronchitis. Prolonged or repeated eye contact may
cause conjunctivitis. Prolonged or repeated skin contact may cause
sensitization dermatitis and possible destruction and/or ulceration.
Chronic ingestion may cause effects similar to those of acute
ingestion. Chronic exposure to water insoluble hexavalent chromium
compounds has been shown to be associated with lung cancer and
gastrointestinal tract tumors.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Get medical aid immediately. Extensive irrigation with water is
required (at least 30 minutes).
Skin:
Get medical aid. Wash clothing before reuse. Rinse area with large
amounts of water for at least 15 minutes. Destroy contaminated shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Strong oxidizer. Contact with other material may
cause fire. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Use water spray to
keep fire-exposed containers cool. Wear appropriate protective
clothing to prevent contact with skin and eyes. Wear a
self-contained breathing apparatus (SCBA) to prevent contact with
thermal decomposition products. Containers may explode in the heat of
a fire. Vapors may be heavier than air. They can spread along the
ground and collect in low or confined areas.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
May require flooding with water in order to eliminate hazardous
reactions since the materials generate their own oxygen.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Sweep up or absorb material, then place into a suitable clean, dry,
closed container for disposal. Avoid generating dusty conditions.
Provide ventilation. Do not use combustible materials such as paper
towels to clean up spill.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Avoid contact with skin and eyes. Keep container
tightly closed. Avoid contact with clothing and other combustible
materials. Avoid ingestion and inhalation. Use with adequate
ventilation. Discard contaminated shoes.
Storage:
Store in a cool, dry, well-ventilated location. Separate from
combustible materials, halogens, sulfides, metals. See also NFPA
430, Code for the Storage of Liquid and Solid Oxidizers.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
