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

EMERGENCY OVERVIEW
Highly flammable.Highly flammable.The toxicological properties of
this material have not been fully investigated.

Potential Health Effects
Eye:
May cause eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
May be harmful if absorbed through the skin. May cause irritation
and dermatitis.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. The toxicological properties of this substance have not
been fully investigated. May be harmful if swallowed. Ingestion of
large amounts may cause CNS depression.
Inhalation:
May cause respiratory tract irritation. The toxicological properties
of this substance have not been fully investigated. Aspiration may
lead to pulmonary edema. May be harmful if inhaled. Vapors may cause
dizziness or suffocation. May cause burning sensation in the chest.
Chronic:
No information found.

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

Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. 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 solid. Will be easily ignited by heat, sparks or
flame. Containers may explode if exposed to fire. Runoff from fire
control or dilution water may cause pollution.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant foam. Water may be ineffective. Water may spread
fire. If water is the only media available, use in flooding amounts.
Do NOT use straight streams of water. 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:
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. Use a spark-proof tool. Provide ventilation.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. 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 away from heat, sparks and
flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld,
braze, solder, drill, grind, or expose empty containers to heat,
sparks or open flames.
Storage:
Keep away from sources of ignition. Store in a cool, dry place. Keep
container closed when not in use. Store in a tightly closed
container. Flammables-area.

**** 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 exhaust ventilation to keep airborne concentrations below the
permissible exposure limits. Use process enclosure, local exhaust
ventilation, or other engineering controls to control airborne
levels.
Exposure Limits
CAS# 870-46-2:


Personal Protective Equipment

Eyes:
Wear safety glasses and chemical goggles if splashing
is possible.
Skin:
Wear appropriate protective gloves and clothing to
prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
Respirators:
Wear a NIOSH/MSHA or European Standard EN 149
approved full-facepiece airline respirator in the
positive pressure mode with emergency escape
provisions.
