highly flammable over 200° C.

Appearance: Clear amber liquid.

Flash Point: >200° C   


Target Organs: Skin, eyes

Potential Health Effects

Eye: Contact may cause slight irritation.

Skin: Weakly irritating to skin.

Ingestion: N/A

Inhalation: N/A

Chronic: Prolonged exposure may cause slight irritation of skin or eyes.

Section 4: First Aid Measures

Eyes: Upon contact, wash eyes throughly with copious amounts of water for
at least 15 minutes, holding the eyes open. Remove contacts if present. Seek 
medical attention.

Skin: Flush area with copious amounts of water. Remove contaminated clothing,
wash thoroughly with soap and water. If irritation persists, seek medical attention.

Ingestion: Arrange transportation to nearest medical facility for immediate
treatment. Do not give an unconscious person anything by mouth. Induct vomiting
ONLY under medical treatment.

Inhalation: Remove victim to fresh air. If breathing is difficult, administer
oxygen. If victim is not breathing, provide artificial respiration. If symptoms persist, 
seek medical attention.

Notes to Physician: Treat supportively and symptomatically.

Section 5: Fire Fighting Measures

                               Low molecular weight hydrocarbons.

Section 6: Accidental Release Measures

General Information: Non-essential personnel should be evacuated upon release
of product. Proper protective equipment should be worn at all times. If possible,
eliminate all sources of ignition and keep the area well ventilated.

Spills/Leaks: Contain the spill and absorb with inert material (earth or dry
sand) and use non-sparking tools to pick up material. Prevent product from entering 
sewers, drains, or other waterways. Place in chemical waste container. Dispose of 
in accordance with all local, state, and federal regulations. 

Section 7: Handling and Storage

Handling: Always wear protective equipment appropriate to the task. Avoid
contact with skin, eyes, and clothing. Always use adequate ventilation. Launder contaminated 
clothing before reuse. Avoid sources of ignition, sparks, and open flames. Wash
thoroughly after handling.

Storage: Store closed containers in a cool, dry location. Keep away from all
sources of ignition. Keep out of the reach of children.

Section 8: Exposure Controls and Personal Protection

Engineering Controls: This product should only be used with local exhaust
ventilation. Safety shower and eye wash stations should be readily accessible 
in work area.
