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

EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and skin. Contact with
combustible material may cause fire.Moisture sensitive.

Potential Health Effects
Eye:
Causes eye irritation. May cause conjunctivitis. May cause
permanent corneal opacification.
Skin:
May cause severe irritation and possible burns.
Ingestion:
May cause burns to the gastrointestinal tract. May cause nausea,
vomiting, and diarrhea, possibly with blood.
Inhalation:
Causes respiratory tract irritation. Can produce delayed pulmonary
edema. May cause acute pulmonary edema, asphyxia, chemical
pneumonitis, and upper airway obstruction caused by edema.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. 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
immediately.
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.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
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 victim ingested or inhaled the
substance; induce artificial respiration with the aid of a pocket
mask equipped with a one-way valve or other proper respiratory
medical device.
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. Strong oxidizer. Contact with other material may
cause fire. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Use water with
caution and in flooding amounts. Some oxidizers may react explosively
with hydrocarbons(fuel). May accelerate burning if involved in a
fire. Containers may explode when heated. Runoff to sewer may create
fire or explosion hazard.
Extinguishing Media:
Do NOT use water directly on fire. Use water spray to cool
fire-exposed containers. Do NOT get water inside containers. Contact
professional fire-fighters immediately. For small fires, do NOT use
dry chemicals, carbon dioxide, halon or foams. USE WATER ONLY. For
large fires flood fire with water from a distance.

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

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
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. Do not use
combustible materials such as paper towels to clean up spill.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid contact with clothing and other
combustible materials. Do not get on skin or in eyes. Do not ingest
or inhale. Do not allow contact with water. Keep from contact with
moist air and steam.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. Store in a tightly closed container. Store in
a cool, dry, well-ventilated area away from incompatible substances.
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
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 10034-81-8:

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.
