**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Irritating to eyes, respiratory system and
skin.The toxicological properties of this material have not been
fully investigated.Moisture sensitive.Highly flammable.
Potential Health Effects
Eye:
Causes eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
Causes skin irritation. May cause cyanosis of the extremities.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. The toxicological properties of this substance have not
been fully investigated. Ingestion of large amounts may cause CNS
depression.
Inhalation:
Causes respiratory tract irritation. May cause respiratory tract
irritation. The toxicological properties of this substance have not
been fully investigated. Aspiration may lead to pulmonary edema.
Vapors may cause dizziness or suffocation. May cause burning
sensation in the chest.
Chronic:
No information found.
**** 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.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water. Wash mouth out with water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
Treat symptomatically and supportively.
**** 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 may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. During a
fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Will burn if involved in a fire.
Containers may explode in the heat of a fire. Flammable liquid and
vapor. Will be easily ignited by heat, sparks or flame. Containers
may explode if exposed to fire.
Extinguishing Media:
Use foam, dry chemical, or carbon dioxide. Water may be ineffective.
Water may spread fire. If water is the only media available, use in
flooding amounts. Do NOT get water inside containers. Do NOT use
straight streams of water. 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:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. 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. Use a spark-proof tool. Provide ventilation. Do
not get water inside containers. A vapor suppressing foam may be
used to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Avoid breathing
dust, vapor, mist, or gas. Avoid contact with eyes, skin, and
clothing. Empty containers retain product residue, (liquid and/or
vapor), and can be dangerous. Take precautionary measures against
static discharges. Keep container tightly closed. Keep away from
heat, sparks and flame. Avoid ingestion and inhalation. Use only in a
chemical fume hood. Wash clothing before reuse. Do not pressurize,
cut, weld, braze, solder, drill, grind, or expose empty containers
to heat, sparks or open flames. Keep from contact with moist air and
steam.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Store in a dry area. Keep under a nitrogen blanket.
Refrigerator/flammables. Store protected from moisture.
**** 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. Use adequate
general or local explosion-proof ventilation to keep airborne levels
to acceptable levels.

CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
