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

EMERGENCY OVERVIEW
Highly flammable. Reacts violently with water. Causes
burns.Corrosive.Water-reactive.Lachrymator (substance which
increases the flow of tears).

Potential Health Effects
Eye:
Causes eye burns. Lachrymator (substance which increases the flow
of tears).
Skin:
Causes skin burns.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns.
Inhalation:
Causes chemical burns to the respiratory tract. Vapors may cause
dizziness or suffocation.
Chronic:
No information found.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
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 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. Water
Reactive. Material will react with water and may release a flammable
and/or toxic gas. 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. May ignite or explode on
contact with steam or moist air.
Extinguishing Media:
Use dry sand or earth to smother fire. Use water spray to cool
fire-exposed containers. Use foam, dry chemical, or carbon dioxide.
DO NOT USE WATER! Contact professional fire-fighters immediately.

**** 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. 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 expose spill to water. A vapor suppressing foam may be used to
reduce vapors.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Do not allow water to get into the container because of violent
reaction. Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. 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 get on skin or in eyes. Do not ingest or inhale. Use
with adequate ventilation. Do not allow contact with water. Discard
contaminated shoes. 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. Keep container closed when not in use. Store in a cool,
dry, well-ventilated area away from incompatible substances. Keep
away from water. Flammables-area.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Use explosion-proof ventilation equipment. 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.
Exposure Limits
CAS# 79-03-8:


Personal Protective Equipment

exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.
