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

EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and skin.Lachrymator
(substance which increases the flow of
tears).Corrosive.Water-reactive.

Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns. Lachrymator (substance which increases the flow of tears).
Skin:
Causes moderate skin irritation. Causes redness and pain.
Ingestion:
Harmful if swallowed. May cause severe and permanent damage to the
digestive tract. Causes gastrointestinal tract burns.
Inhalation:
May be fatal if inhaled. May cause severe irritation of the
respiratory tract with sore throat, coughing, shortness of breath
and delayed lung edema. Inhalation may be fatal as a result of
spasm, inflammation, edema of the larynx and bronchi, chemical
pneumonitis and pulmonary edema. Causes severe respiratory tract
irritation with possible burns.
Chronic:
May cause digestive tract disturbances.

**** 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. 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 not breathing, give artificial respiration. If
breathing is difficult, give oxygen. 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. 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. Vapors may be heavier than air. They can spread
along the ground and collect in low or confined areas.
Extinguishing Media:
For large fires, use water spray, fog, or alcohol-resistant foam. Do
NOT get water inside containers. Do NOT use straight streams of
water. For small fires, use dry chemical, dry sand, alcohol-resistant
foam.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up, then place into a suitable container for
disposal. Avoid generating dusty conditions. Remove all sources of
ignition. Provide ventilation. Do not get water inside containers.

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

Handling:
Keep container tightly closed. Do not get on skin or in eyes. Do not
ingest or inhale. Use with adequate ventilation. Discard contaminated
shoes.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Corrosives
area. Keep containers tightly closed.

**** 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.
Exposure Limits
CAS# 108-77-0:

Russia: 0.1 mg/m3 TWA

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 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.
