**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Flammable. Irritating to eyes, respiratory system and skin. May
cause cancer.Moisture sensitive.Lachrymator (substance which
increases the flow of tears).

Potential Health Effects
Eye:
Produces irritation, characterized by a burning sensation, redness,
tearing, inflammation, and possible corneal injury. Lachrymator
(substance which increases the flow of tears). 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. Ingestion of large amounts may cause CNS depression.
Inhalation:
Causes respiratory tract irritation. Aspiration may lead to
pulmonary edema. Vapors may cause dizziness or suffocation.
Inhalation at high concentrations may cause CNS depression and
asphixiation. May cause burning sensation in the chest.
Chronic:
Effects may be delayed.

**** 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. Do
NOT allow victim to rub eyes or keep eyes closed.
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.
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. Use
water spray to keep fire-exposed containers cool. Containers may
explode in the heat of a fire. Flammable liquid and vapor. Vapors
may be heavier than air. They can spread along the ground and
collect in low or confined areas. Runoff from fire control or
dilution water may cause pollution.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. Water may be ineffective. Do NOT get water inside
containers. Do NOT use straight streams of water.

**** 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:
Wash thoroughly after handling. Use only in a well-ventilated area.
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Avoid contact with
eyes, skin, and 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. Avoid ingestion and
inhalation. Do not allow contact with water. 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 heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Flammables-area. Keep
refrigerated. (Store below 4C/39F.) 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 general or
local explosion-proof ventilation to keep airborne levels to
acceptable levels.
Exposure Limits
CAS# 3970-21-6:


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 29
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.
