**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Contact with acids liberates toxic gas. Causes
burns. Contact with combustible material may cause fire.Corrosive.
Potential Health Effects
Eye:
Causes eye burns. May result in corneal injury. May cause
blepharitis (inflammation of the margins of the eyelids).
Skin:
Causes severe burns with delayed tissue destruction.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive
tract. May be harmful if swallowed.
Inhalation:
Causes chemical burns to the respiratory tract. Aspiration may lead
to pulmonary edema. May cause systemic effects. Causes corrosive
action on the mucous membranes.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Prolonged
or repeated eye contact may cause conjunctivitis. Effects may be
delayed. Laboratory experiments have resulted in mutagenic effects.
**** 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. 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:
Do NOT induce vomiting. 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 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:
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 combustible materials
may cause a 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. Use water with caution
and in flooding amounts. Contaminating or mixing with foreign
materials such as combustibles, grease, and fuels can cause fire.
Containers may explode when heated.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Contact
professional fire-fighters immediately. Cool containers with flooding
quantities of water until well after fire is out. For small fires, do
NOT use dry chemicals, carbon dioxide, halon or foams. USE WATER
ONLY. For large fires, flood fire area with water from a distance.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid runoff into storm sewers and ditches which lead to
waterways. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Remove all sources of ignition. Provide ventilation. Do not get water
inside containers. 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. Use only in a well-ventilated area. Minimize dust
generation and accumulation. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Avoid contact with heat,
sparks and flame. Avoid contact with clothing and other combustible
materials. Do not ingest or inhale. Discard contaminated shoes.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Do not store near combustible materials. Keep container
closed when not in use. Store in a tightly closed container. Store
in a cool, dry, well-ventilated area away from incompatible
substances. Keep away from acids.
**** 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
ventilation to keep airborne concentrations low.
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:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant a respirator's use.
