**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Causes burns. May cause sensitization by
inhalation and skin contact.Moisture sensitive.Corrosive.
Potential Health Effects
Eye:
Causes eye burns. May cause conjunctivitis. Causes redness and
pain. Exposure to high fume concentrations cause photophobia,
double vision, and "halo" vision.
Skin:
Causes skin burns. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Causes redness and pain. May cause blistering of the skin.
Ingestion:
Harmful if swallowed. Causes gastrointestinal tract burns.
Inhalation:
May cause asthmatic attacks due to allergic sensitization of the
respiratory tract. Causes chemical burns to the respiratory tract.
Inhalation of high concentrations may cause pulmonary edema.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Repeated
exposure may cause allergic respiratory reaction (asthma).
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub or keep eyes
closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Flush skin with plenty of soap and
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Get medical aid immediately. Remove from exposure to fresh air
immediately. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
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. Vapors may be heavier than air. They can spread
along the ground and collect in low or confined areas. Contact with
metals may evolve flammable hydrogen gas.
Extinguishing Media:
Use carbon dioxide. Use alcohol foam. Do NOT use dry powder.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up or absorb material, then place into a
suitable clean, dry, closed container for disposal. Avoid generating
dusty conditions. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Minimize dust generation and accumulation. Do not get in eyes, on
skin, or on clothing. Do not ingest or inhale.
Storage:
Store in a cool, dry place. Store in a tightly closed container.
Corrosives area. Do not store in metal containers.
**** 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 to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
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.
