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

from exposure to fresh air immediately. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid if cough or
other symptoms appear.
Notes to Physician: Treat
symptomatically and supportively.
Section 5 - Fire
Information: During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Wear appropriate protective
clothing to prevent contact with skin and eyes. Wear a self-contained breathing
apparatus (SCBA) to prevent contact with thermal decomposition products.
Extinguishing Media: Use agent most appropriate to
extinguish fire. Do NOT get water inside containers. In case of fire, use carbon
dioxide, dry chemical powder or appropriate foam.
Section 6 -
Accidental Release Measures
Information: Use proper personal protective equipment as indicated in
