**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Irritating to eyes, respiratory system and
skin. May cause sensitization by skin contact. May cause heritable
genetic damage. 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.
Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns. Exposure to particulates or solution may cause
conjunctivitis, ulceration, and corneal abnormalities.
Skin:
May cause skin sensitization, an allergic reaction, which becomes
evident upon re-exposure to this material. Contact with skin causes
irritation and possible burns, especially if the skin is wet or
moist. May cause dermatitis.
Ingestion:
May cause severe and permanent damage to the digestive tract. May
cause liver and kidney damage. May cause severe digestive tract
irritation with abdominal pain, nausea, vomiting and diarrhea.
Inhalation:
May cause asthmatic attacks due to allergic sensitization of the
respiratory tract. May cause ulceration and perforation of the nasal
septum if inhaled in excessive quantities. May cause severe
irritation of the upper respiratory tract with pain, burns, and
inflammation. Causes chemical burns to the respiratory tract. May
cause chemical bronchitis with coughing and difficulty in breathing.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those
of acute inhalation and ingestion. Prolonged or repeated exposure
may lead to asthma and perforation of the nasal septum. Repeated
inhalation may cause chronic bronchitis. May cause liver and kidney
damage. May cause cancer in humans.
**** 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.
Skin:
Get medical aid immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
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. Containers may
explode in the heat of a fire. Runoff from fire control or dilution
water may cause pollution.
Extinguishing Media:
Do NOT use dry chemicals, CO2, Halon or foams. Use water only in
flooding quantities as fog.
**** 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. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation. Keep combustibles (wood, paper, oil, etc.,) away
from spilled material.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. 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. Use with
adequate ventilation. Discard contaminated shoes.
Storage:
Do not store near combustible materials. Keep container closed when
not in use. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep containers tightly closed. Avoid
storage on wood floors.
**** 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.
