FIRST AID FOR INHALATION: ...................................................... Remove to fresh air. If effects persist, consult a physician.
FIRST AID FOR INGESTION: ........................................................ Do not induce vomiting. Get medical attention if significant amounts
are ingested.
5. FIRE FIGHTING MEASURES:
FLASH POINT: ............................................................................... 188癈 (Tag CC).
EXTINGUISHING MEDIA: .............................................................. Foam, carbon dioxide (CO2) or dry chemical.
SPECIAL FIRE FIGHTING PROCEDURES: Burning will generate toxic fumes. Use a self-contained breathing apparatus and
appropriate protective clothing when fighting fires in an enclosed area. Cool exposed containers with water spray.
6. ACCIDENTAL RELEASE MEASURES:
SPILL OR LEAK PROCEDURES: Sweep and shovel or use properly grounded vacuum equipment. Do so in a manner that
minimizes airborne dust.
7. HANDLING AND STORAGE:
STORAGE TEMPERATURE (min./max.): ..................................... 0癋 (-17癈)/90癋 (32癈)
STORAGE: ..................................................................................... Store in a tightly closed container. Keep away from open flame.
HANDLING PRECAUTIONS: ......................................................... Avoid handling that will unnecessarily generate airborne dust. Properly
ground all material handling equipment to prevent static discharge.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION:
EYE PROTECTION GUIDELINES: ................................................ Safety glasses or goggles are recommended, depending on the
expected level of exposure.
SKIN PROTECTION GUIDELINES:............................................... Areas expected to have repeated exposure, such as hands, may need
to be protected by an liquid-proof glove (such as neoprene or nitrile) to prevent irritation. Barrier creams can be used effectively.
RESPIRATORY/VENTILATION GUIDELINES:
Work environments should be maintained below applicable exposure levels through the use of engineering controls, such as dilution and
exhaust ventilation. If this is not feasible, use a NIOSH approved dust mask/respirator for nuisance dust. A respirator with an organic
vapor cartridge may be necessary for certain sensitized individuals.
ADDITIONAL PROTECTIVE MEASURES:.................................... Practice good industrial hygiene by washing with soap and water after
each use. Avoid inhalation. Generally speaking, working cleanly and following basic precautionary measures will greatly minimize the
potential for harmful exposure to this product under normal use conditions.
OCCUPATIONAL EXPOSURE LIMITS: ........................................ This product should be treated as a nuisance dust. Refer to OSHA's
