Section 4 - First Aid Measures
|
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes.

breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Persons with asthma may be at increased risk from exposure to this
product. Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
|
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Substance
is noncombustible.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Use water spray, dry chemical, carbon dioxide, or alcohol-resistant
foam.
Flash Point: Not applicable.
Autoignition Temperature: Not applicable.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 1; Flammability: 0; Instability: 0
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid generating dusty conditions. Provide ventilation.
Clean up residual material by washing area with a 2-5% solution of
soda ash.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid breathing dust, vapor, mist, or
gas. Avoid contact with eyes, skin, and clothing. Empty containers
retain product residue, (liquid and/or vapor), and can be dangerous.
Avoid ingestion and inhalation.
Storage:
Keep container closed when not in use. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
