**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes severe burns. Contact with combustible material may cause
fire.Corrosive.
Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury.
Skin:
May cause deep, penetrating ulcers of the skin. May cause skin
discoloration. Exposure of the skin to the liquid or concentrated
vapor produces severe and penetrating burns.
Ingestion:
Causes gastrointestinal tract burns. May cause perforation of the
digestive tract.
Inhalation:
Effects may be delayed. May cause irritation of the respiratory
tract with burning pain in the nose and throat, coughing, wheezing,
shortness of breath and pulmonary edema. Inhalation may be fatal as
a result of spasm, inflammation, edema of the larynx and bronchi,
chemical pneumonitis and pulmonary edema. Pronlonged exposure to low
concentrations of the vapor may lead to chronic bronchitis and/or
loss of apetite.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. 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.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately. Do NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Discard contaminated clothing in a manner which limits
further exposure. 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. Do NOT induce vomiting and seek IMMEDIATE MEDICAL
ADVICE.
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.
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. Use water spray to keep fire-exposed containers cool.
Substance is noncombustible. Vapors may accumulate in confined
spaces Contact with metals may evolve flammable hydrogen gas.
Substance may react with water, and may release corrosive and/or
toxic gases.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire. Do NOT use straight streams of water.
Cool containers with flooding quantities of water until well after
fire is out.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Neutralize spill with sodium
bicarbonate. Use water spray to disperse the gas/vapor. Do not get
water inside containers. A vapor suppressing foam may be used to
reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Do not get in
eyes, on skin, or on clothing. Keep container tightly closed. Do not
ingest or inhale.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Bottles
should be vented periodically in order to overcome pressure buildup.
**** 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.
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves and clothing to
prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Wear a NIOSH/MSHA or European Standard EN 149
approved full-facepiece airline respirator in the
positive pressure mode with emergency escape
provisions. Follow the OSHA respirator regulations
found in 29 CFR 1910.134 or European Standard EN 149.
Always use a NIOSH or European Standard EN 149
approved respirator when necessary.
