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

EMERGENCY OVERVIEW
Highly flammable. Toxic by inhalation, in contact with skin and if
swallowed.Highly flammable.The toxicological properties of this
material have not been fully investigated.Lachrymator (substance
which increases the flow of tears).

Potential Health Effects
Eye:
May cause eye irritation. Lachrymator (substance which increases
the flow of tears).
Skin:
May cause skin irritation.
Ingestion:
May cause irritation of the digestive tract. The toxicological
properties of this substance have not been fully investigated.
Inhalation:
May cause respiratory tract irritation. The toxicological properties
of this substance have not been fully investigated. Vapors may cause
dizziness or suffocation.
Chronic:
No information found.

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

Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Immediately flush
eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Get medical aid. Get medical aid
immediately.
Skin:
Get medical aid. Get medical aid immediately. Flush skin with plenty
of water for at least 15 minutes while removing contaminated clothing
and shoes. 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. Get medical aid immediately. Do NOT induce vomiting. If
conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or
water. Wash mouth out with water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
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. Use water spray to keep fire-exposed
containers cool. Flammable liquid and vapor. Vapors may be heavier
than air. They can spread along the ground and collect in low or
confined areas. Will be easily ignited by heat, sparks or flame.
Containers may explode if exposed to fire.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Water may be ineffective. Water may spread
fire. If water is the only media available, use in flooding amounts.
For large fires, use water spray, fog or alcohol-resistant foam. 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:
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.

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

Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Ground and bond containers when transferring material. Avoid contact
with eyes, skin, and clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Keep container
tightly closed. 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 heat and flame. 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# 503-20-8:
