4. First Aid Measures
Eye: Immediately flush with plenty of clean water for at least 15 minutes. Seek medical attention.
Skin: Remove contaminated clothing. Clean affected area(s) thoroughly with soap and water. Seek medical attention.
Inhalation: Remove to fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration. Get
medical attention.
Ingestion: Seek medical attention! Do NOT induce vomiting. If vomiting occurs spontaneously, keep head below hips
to prevent aspiration of liquid into lungs.
SEEK MEDICAL ATTENTION IF SYMPTOMS PERSIST.
5. Fire Fighting Measures
Flash Point (method used): 175oF (Setaflash CC) (79o C)
Flammable Limits (% volume in air): Lower = ND Upper = ND
Auto Ignition Temperature: Not data available
Extinguishing Media: Extinguish with water fog, dry chemical, CO2 or foam.
Hazard Combustion Products: Hazardous conditions will result through contamination with incompatibles or exposure
to excessive temperatures. Product can decompose with force if confined during exposure to fire.
Fire Fighting Instructions: Do not enter confined fire space without full bunker gear including a positive pressure, NIOSH
approved, self-contained breathing apparatus. Cool containers exposed to fire with water.
6. Accidental Release Measures
Spill: Eliminate all ignition sources. Handling equipment must be grounded to prevent sparking. Avoid personal contact.
If spill is indoors, ventilate area. Keep out of drains, sewers or waterways. Take up with absorbent material, place
into non-leak containers and seal tightly for proper disposal.
7. Handling and Storage
Handling: Avoid inhalation of vapors and personal contact with product. Static electricity may create a fire hazard.
Always ground equipment and transfer containers. Keep liquid away from heat, sparks and flame. Use with adequate
ventilation. "Empty" containers can contain explosive vapors. Keep away from sources of ignition and excessive heat.
Storage: Store containers tightly closed with adequate ventilation in a cool, dry area.
8. Exposure Controls / Personal Protection
Exposure Controls: Mechanical and local exhaust should be used for indoor use.
Personal Protection: NIOSH approved organic solvent respirator, impervious gloves, chemical splash goggles and
protective clothing to minimize skin contact.
