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

EMERGENCY OVERVIEW
Highly flammable. Reacts violently with water. Causes burns.Highly
flammable.Water-reactive.Corrosive.

Potential Health Effects
Eye:
Causes eye burns.
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. 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. Water may be ineffective.
Material is lighter than water and a fire may be spread by the use of
water. Flammable liquid and vapor. Reacts violently with water.
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. Will be easily ignited by heat, sparks or
flame. Containers may explode if exposed to fire.
Extinguishing Media:
Use dry sand or earth to smother fire. If water is the only media
available, use in flooding amounts. Use dry chemical to fight fire.
DO NOT USE WATER! Contact professional fire-fighters immediately.
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. Scoop up
with a nonsparking tool, then place into a suitable container for
disposal. Remove all sources of ignition. Use a spark-proof tool.
Provide ventilation. Do not expose spill to water.

**** 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. Do not breathe dust,
vapor, mist, or gas. Do not get in eyes, on skin, or on clothing.
Empty containers retain product residue, (liquid and/or vapor), and
can be dangerous. Keep away from heat, sparks and flame. 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 and flame. Keep away from sources of ignition.
Store in a tightly closed container. Store in a dry area. Keep away
from water. Flammables-area. Keep refrigerated. (Store below
4C/39F.)

**** 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# 3880-03-3:


Personal Protective Equipment

Eyes:

Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
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.
