Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Highly flammable. Harmful by inhalation, in contact with skin and if swallowed. Irritating to eyes. May cause cancer.Stench.
Potential Health Effects
Eye:
Causes eye irritation. Lachrymator (substance which increases the flow of tears).
Skin:
Causes skin irritation. May be harmful if absorbed through the skin.
Ingestion:
Harmful if swallowed. May cause irritation of the digestive tract.
May cause nausea and vomiting.
Inhalation:
Harmful if inhaled. Causes respiratory tract irritation.
Chronic:
Chronic exposure to benzene has been associated with an increased incidence of leukemia and multiple myeloma (tumor composed of cells of the type normally found in the bone marrow). Immunodepressive effects have been reported.

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:

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. Extremely flammable liquid and vapor. Vapor may cause flash fire. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas.
Extinguishing Media:
Use water spray, dry chemical, or carbon dioxide.

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.
Spills/Leaks:

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. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Use only with adequate ventilation. Keep away from heat, sparks and flame. Avoid breathing vapor.
Storage:
Keep away from sources of ignition. Store in a cool, dry place.
Store in a tightly closed container. Flammables-area. Separate from oxidizing materials.
