4. FIRST AID MEASURES

SKIN: Promptly wash the skin with soap and water. Remove contaminated clothing and wash before reuse. Get
medical attention for any symptoms.

EYES: Flush eyes with water for at least 15 minutes. Get medical attention.

INHALATION: Move victim to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult,
give oxygen provided a qualified operator is available. Get medical attention.

INGESTION: Immediately give 2 鈥? 4 glasses of water and induce vomiting by touching finger to the back of the

5. FIRE FIGHTING MEASURES

FLAMMABLE PROPERTIES

FLASH POINT: 46F
FLASH POINT METHOD: TCC
AUTOIGNITION TEMPERATURE: 838F
UPPER FLAME LIMIT (volume % in air): 8.70
LOWER FLAME LIMIT (volume % in air): 1.56
FLAME PROPAGATION RATE (solids): Not applicable
OSHA FLAMMABILITY CLASS: Flammable liquid, 1B

EXTINGUISHING MEDIA:
Water spray, fog or mist, 鈥渁lcohol鈥? foam, carbon dioxide, dry chemicals, sand, dolomite, etc.

UNUSUAL FIRE AND EXPLOSION HAZARDS:
Vapors are heavier than air and may spread near ground to sources of ignition. May travel considerable distance
to source of ignition and flash back. Forms explosive mixtures with air.

SPECIAL FIRE FIGHTING PRECAUTIONS/INSTRUCTIONS:
Firefighters should wear self-contained breathing apparatus and full, protective clothing. Cool containers exposed
to flames with water from the side until well after the fire is out.

6. ACCIDENTAL RELEASE MEASURES

IN CASE OF SPILL OR OTHER RELEASE: (See section 8 for recommended personal protective equipment.)
Extinguish all ignition sources. Avoid sparks, flames, heat and smoking. Ventilate area. Runoff or release to
sewer, waterway or ground is forbidden. Absorb small quantities with paper towels and evaporate in a safe place
(fume hood). Allow sufficient time for vapors to completely clear the hood ducts, then burn the paper in a location
away from combustible materials.

Spills and releases may have to be reported to Federal and/or local authorities. See Section 15 regarding
reporting requirements.

7. HANDLING AND STORAGE

NORMAL HANDLING: (See section 8 for recommended personal protective equipment.)
Keep away from heat, sparks and open flames. Avoid contact with skin and eyes. Avoid breathing vapors.
Ventilate area well. Use approved respirator if air contamination is above accepted level.

STORAGE RECOMMENDATIONS:
Flammable liquid storage. Keep away from oxidizers, heat, sparks and open flames. Ground container and
transfer equipment to eliminate static electric sparks.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

ENGINEERING CONTROLS:
Provide adequate general and local exhaust ventilation.

PERSONAL PROTECTIVE EQUIPMENT

SKIN PROTECTION: Use protective gloves and other protective clothing to prevent skin contact.

EYE PROTECTION: Use chemical safety goggles.

RESPIRATORY Use approved respirator if high airborne concentrations exist.
PROTECTION:
ADDITIONAL Eyewash and quick-drench showers.
