**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Reacts violently with water. Causes severe burns. Irritating to
respiratory system.Corrosive.
Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury.
Skin:
Causes skin burns.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns.
Inhalation:
May cause severe irritation of the respiratory tract with sore
throat, coughing, shortness of breath and delayed lung edema. Causes
chemical burns to the respiratory tract. May be harmful if inhaled.
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.
**** 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. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
SPEEDY ACTION IS CRITICAL!
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 and move to fresh
air immediately. If breathing is difficult, give oxygen.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
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. Contact with
water can cause violent liberation of heat and splattering of the
material.
Extinguishing Media:
Do NOT use water directly on fire. Use water spray to cool
fire-exposed containers. Use dry chemical to fight fire.
**** 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. Cover with sand, dry lime or soda ash and place in
a closed container for disposal.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not get in eyes, on skin, or on clothing. Keep
container tightly closed. Do not allow contact with water. Use only
in a chemical fume hood.
Storage:
Do not store near combustible materials. Keep container closed when
not in use. Store in a dry area. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not store
near alkaline substances.
**** 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.
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 gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
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.
