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

EMERGENCY OVERVIEW
Flammable. Toxic if swallowed.Air sensitive.Light sensitive.Moisture
sensitive.

Potential Health Effects
Eye:
May cause eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
May cause irritation and dermatitis. May cause cyanosis of the
extremities.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Ingestion of large amounts may cause CNS depression. May
cause urine discoloration and lung and liver injury.
Inhalation:
May cause respiratory tract irritation. Aspiration may lead to
pulmonary edema. Vapors may cause dizziness or suffocation. 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.
Skin:
Get medical aid if irritation develops or persists. Wash clothing
before reuse. Flush skin with plenty of soap and water.
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:
Remove from exposure and move to fresh air immediately. Get medical
aid if cough or other symptoms appear. Do NOT use mouth-to-mouth
resuscitation.
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 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.
Flammable Liquid. Can release vapors that form explosive mixtures at
temperatures above the flashpoint. Use water spray to keep
fire-exposed containers cool. Water may be ineffective. Material is
lighter than water and a fire may be spread by the use of water.
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.
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. Remove all sources of ignition. Use
a spark-proof tool. Place under an inert atmosphere. 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 with adequate ventilation.
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. Store protected from light. Handle under an inert
atmosphere. Store protected from air. Do not allow contact with
water. 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. Do not store in direct sunlight. Store in a tightly closed
container. Flammables-area. Do not expose to air. Store protected
from moisture. Store protected from light. Store under an inert
atmosphere.

**** 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# 109-97-7:


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.
