Section 4 - First Aid Measures
Flush eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Get medical aid.
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
Get medical aid. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
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
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. Use water
spray to keep fire-exposed containers cool. Vapors may be heavier
than air. They can spread along the ground and collect in low or
confined areas. Containers may explode when heated.
Use agent most appropriate to extinguish fire. Cool containers with
flooding quantities of water until well after fire is out. Use water
spray, dry chemical, carbon dioxide, or appropriate foam.

(estimated) Health: 1; Flammability: 1; Instability: 0
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated
in Section 8.
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Provide ventilation.
Section 7 - Handling and Storage
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Avoid contact with
eyes, skin, and clothing. Keep container tightly closed. Avoid
ingestion and inhalation.
Keep away from sources of ignition. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep refrigerated. (Store below 4°C/39°F.)
Section 8 - Exposure Controls, Personal Protection
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.
