**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic if swallowed. Causes burns. May cause sensitization by skin
contact. Contact with combustible material may cause fire. May cause
cancer by inhalation. Very toxic to aquatic organisms, may cause
long-term adverse effects in the aquatic
environment.Corrosive.Oxidizer.
Potential Health Effects
Eye:
Causes eye burns. May cause permanent corneal opacification. May
cause chemical conjunctivitis and corneal damage.
Skin:
Causes skin burns. May be absorbed through the skin in harmful
amounts. May cause skin rash (in milder cases), and cold and clammy
skin with cyanosis or pale color. May cause sensitization by skin
contact.
Ingestion:
Harmful if swallowed. May cause severe and permanent damage to the
digestive tract. Causes gastrointestinal tract burns. May cause liver
and kidney damage. May cause perforation of the digestive tract.
Exposure may cause anemia and other blood abnormalities. May cause
systemic effects.
Inhalation:
Causes chemical burns to the respiratory tract. Aspiration may lead
to pulmonary edema. May cause systemic effects.
Chronic:
Repeated exposure may cause sensitization dermatitis. Effects may be
delayed. Adverse reproductive effects have been reported in animals.
Confirmed Human Carcinogen.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes 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
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 and move 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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
with caution and in flooding amounts. Oxidizer. Greatly increases the
burning rate of combustible materials. Some oxidizers may react
explosively with hydrocarbons(fuel). May accelerate burning if
involved in a fire. Containers may explode when heated.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Contact professional fire-fighters immediately. Cool containers with
flooding quantities of water until well after fire is out. For large
fires flood fire with water from a distance.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Remove all sources of ignition. Absorb spill using
an absorbent, non-combustible material such as earth, sand, or
vermiculite. Do not use combustible materials such as sawdust.
Provide ventilation. Do not use combustible materials such as paper
towels to clean up spill.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on
skin, or on clothing. Keep container tightly closed. Avoid contact
with clothing and other combustible materials. Do not ingest or
inhale. Discard contaminated shoes.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. Keep container closed when not in use.
**** 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.
