4. EMERGENCY AND FIRST AID PROCEDURES.
Eye: Immediately flush eyes with large quantities of water, for at least 15 minutes, holding the eyelids apart.
Get immediate medical attention.
Skin: Wash with soap and water. Remove contaminated clothing. Wash contaminated clothing before reuse. If

5. FIRE FIGHTING MEASURES
Flashpoint: 6°F (TCC) (Based on THF)
Flammable Limits: LEL: 2.0 % UEL: 11.8 %
Autoignition Temperature: Not determined
Extinguishing Media: Foam, Dry Chemical or Carbon Dioxide.
Unusual Fire or Explosion Hazards: Vapors are heavier than air, and will travel considerable distance to
source of ignition causing a flashback. On long standing may form peroxides which may cause violent reactions
especially upon evaporation to dryness.
Special Fire-Fighting Instructions: Handle as flammable liquid. Firefighters should wear positive pressure
self-contained breathing apparatus and chemical goggles. Water may be ineffective but should be used to keep
fire exposed containers cool.
Hazardous Combustion Products: Carbon Dioxide and Carbon Monoxide are formed. Irritating peroxide
fumes are formed when heated to decomposition.
6. ACCIDENTAL RELEASE MEASURES
Eliminate all sources of ignition. Ventilate area. Wear appropriate personal protection equipment. Absorb with
inert absorbing material and dispose of with solid waste according to Federal, State and Local regulations.
Wash spill area with water. Do not flush wash water into confined areas.
7. HANDLING AND STORAGE
Handling: Do not get in eyes, on skin or clothing. Avoid breathing vapors. Keep product away from heat,
sparks and open flames and all sources of ignition. Use with adequate ventilation. Wash thoroughly with soap
and water after handling. Keep containers closed when not in use.
Storage: Store in a cool, dry, well ventilated area away from incompatible materials. Store only in original
container. Keep containers closed when not in use, and away from open flame or other sources of ignition.
