**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes severe burns. May cause sensitization by skin contact. May
cause heritable genetic damage. 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.Cancer suspect agent.Corrosive.Light
sensitive.Water-reactive.
Potential Health Effects
Eye:
Causes eye burns. Vapors cause eye irritation.
Skin:
Causes skin burns. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
May cause blistering of the skin.
Ingestion:
May cause severe and permanent damage to the digestive tract.
Inhalation:
May cause severe allergic respiratory reaction. Causes chemical
burns to the respiratory tract.
Chronic:
May cause liver and kidney damage. 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:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
**** 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. Water Reactive.
Material will react with water and may release a flammable and/or
toxic gas. Containers may explode in the heat of a fire. Contact
with metals may evolve flammable hydrogen gas. Use water spray to
knock down acid vapors.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
If water is the only media available, use in flooding amounts. Do NOT
get water inside containers. Contact professional fire-fighters
immediately. Cool containers with flooding quantities of water until
well after fire is out. For small fires, use dry chemical or carbon
dioxide.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Remove all sources of ignition. Absorb spill using
an absorbent, non-combustible material such as earth, sand, or
vermiculite. Do not use combustible materials such as sawdust.
Provide ventilation. Do not expose spill to water. Do not get water
inside containers.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Avoid contact with clothing
and other combustible materials. Avoid ingestion and inhalation.
Discard contaminated shoes. Use only with adequate ventilation.
Storage:
Do not store near combustible materials. Keep container closed when
not in use. Store in a cool, dry, well-ventilated area away from
incompatible substances. Corrosives area. Water free area. Do not
store in metal containers. Store protected from light. Containers may
be glass, aluminum, stainless steel.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.
