**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes severe burns.Corrosive.Oxidizer.
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:
Harmful if inhaled. 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.
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. Prolonged or repeated skin contact may cause
sensitization dermatitis and possible destruction and/or ulceration.
Chronic ingestion may cause effects similar to those of acute
ingestion.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and 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 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. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. 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 carbon dioxide or dry chemical.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
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. Use with adequate ventilation. Do not get in eyes,
on skin, or on clothing. Keep container tightly closed. Avoid
ingestion and inhalation. Do not allow contact with water.
Storage:
Do not store near combustible materials. Store in a tightly closed
container. 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 adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
