Section 4 - First Aid Measures
|
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid imme
diately.
Skin:
Immediately flush skin with plenty of water for at least 15 minutes
while removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Wash clothing before reuse.

aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
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. Vapors may
be heavier than air. They can spread along the ground and collect
in low or confined areas.
Extinguishing Media:
Water spray may cause frothing. Use dry chemical or carbon dioxide.
Flash Point: 127 deg C ( 260.60 deg F)
Autoignition Temperature: 470 deg C ( 878.00 deg F)
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 2; Flammability: 1; 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. Reduce airborne dust and prevent scattering by moistening
with water. Clean up spills immediately, observing precautions in
the Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Use with adequate
ventilation. Minimize dust generation and accumulation. Avoid
contact with skin and eyes. Avoid breathing dust.
Storage:
Store in a cool, dry place. Do not store in direct sunlight. Keep
container closed when not in use.
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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
