**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed. Causes
burns. May cause sensitization by skin contact. May cause cancer.
Very toxic to aquatic organisms, may cause long-term adverse effects
in the aquatic environment.Corrosive.Cancer suspect agent.
Potential Health Effects
Eye:
May cause irreversible eye injury. Exposure to the vapors or
liquid may cause temporary blindness. Causes severe eye irritation
and burns.
Skin:
May be fatal if absorbed through the skin. Prolonged and/or repeated
contact may cause irritation and/or dermatitis. May cause skin
sensitization, an allergic reaction, which becomes evident upon
re-exposure to this material. Contact with liquid is corrosive and
causes severe burns and ulceration. Contact with the skin may
dissolve hair.
Ingestion:
Harmful if swallowed. Causes gastrointestinal irritation with
nausea, vomiting and diarrhea. May cause liver and kidney damage.
Causes digestive tract burns with immediate pain, swelling of the
throat, convulsions, and possible coma. Exposure may cause anemia
and other blood abnormalities.
Inhalation:
Harmful if inhaled. Irritation may lead to chemical pneumonitis and
pulmonary edema. May cause liver and kidney damage. Causes severe
irritation of upper respiratory tract with coughing, burns,
breathing difficulty, and possible coma. Vapors may cause dizziness,
nausea, itching, burning, and swelling of the eyes.
Chronic:
Repeated inhalation may cause chronic bronchitis. May cause cancer
according to animal studies. Repeated exposure may cause
sensitization dermatitis. May cause reproductive and fetal effects.
**** 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. Do NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Discard contaminated clothing in a manner which limits
further exposure.
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. Vapors can travel to a source of ignition and flash
back. Use water spray to keep fire-exposed containers cool.
Autoignition temperature varies based upon contact surface. Vapors
may be heavier than air. They can spread along the ground and
collect in low or confined areas. Vapors may form an explosive
mixture with air. Containers may explode when heated. Combustible
liquid and vapor.
Extinguishing Media:
For large fires, use water spray, fog, or alcohol-resistant foam.
Use water spray to cool fire-exposed containers. Do NOT get water
inside containers. For small fires, use dry chemical, carbon
dioxide, or water spray. Cool containers with flooding quantities of
water until well after fire is out.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Use water spray to disperse the gas/vapor. 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. Do not get water inside containers. A vapor
suppressing foam may be used to reduce vapors. Water spray may
reduce vapor but may not prevent ignition in closed spaces.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Ground and
bond containers when transferring material. Use spark-proof tools and
explosion proof equipment. Do not get in eyes, on skin, or on
clothing. Empty containers retain product residue, (liquid and/or
vapor), and can be dangerous. Keep container tightly closed. Keep
away from heat, sparks and flame. Do not ingest or inhale. Store
protected from light. Do not pressurize, cut, weld, braze, solder,
drill, grind, or expose empty containers to heat, sparks or open
flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Do not store in direct sunlight. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Storage under a nitrogen blanket has been
recommended.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate general or local explosion-proof ventilation to keep
airborne levels to acceptable levels.
