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

EMERGENCY OVERVIEW
Flammable.

Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be harmful if absorbed through the
skin. Contact with the skin may cause erythema (redness), dryness,
and defatting.
Ingestion:
May cause irritation of the digestive tract. Possible aspiration
hazard. May be harmful if swallowed.
Inhalation:
May cause respiratory tract irritation. May be harmful if inhaled.
May cause central nervous system effects such as nausea and headache.
Chronic:
Chronic exposure to xylene may cause defatting dermatitis,
reversible eye damage, dyspnea (labored breathing), confusion,
dizziness, apprehension, memory loss, headache, tremors, weakness,
anorexia, nausea, ringing in the ears, irritability, thirst, mild
changes in liver function, kidney impairment, anemia, and
hyperplasia, but not destruction, of the bone marrow.

**** 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:
Potential for aspiration if swallowed. Get medical aid immediately.
Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person.
Inhalation:
Remove from exposure and move to fresh air immediately. 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. Will burn if involved in a fire. Flammable liquid
and vapor.
Extinguishing Media:
Use carbon dioxide or dry chemical.

**** 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. Remove all sources of ignition.
Use a spark-proof tool. Provide ventilation.

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

Handling:
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Avoid contact with
eyes, skin, and clothing. Use only with adequate ventilation. Keep
away from heat, sparks and flame. Avoid breathing vapor or mist.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. 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
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 452-64-2:


Personal Protective Equipment

Eyes:
