**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. 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 or keep eyes closed.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
soap and 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 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. Flammable
liquid and vapor. 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. May be ignited by heat,
sparks, and flame. Vapors may form an explosive mixture with air.
Containers may explode when heated.
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 saw dust. 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. Avoid
contact with 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:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local explosion-proof ventilation to keep airborne levels to
acceptable levels.
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 protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29CFR
1910.134 or European Standard EN 149. Always use a
NIOSH or European Standard EN 149 approved respirator
when necessary.
