Section
4: First Aid Measures Eye Contact:
Check
for and remove any contact lenses. In case of contact, immediately flush eyes
with plenty of water for at least 15 minutes. Get medical attention.
Skin
Contact: In case of
contact, immediately flush skin with plenty of water. Cover the irritated skin
with an emollient. Remove contaminated clothing and shoes. Wash clothing before
reuse. Thoroughly clean shoes before reuse. Get medical attention.

Products
of Combustion: These
products are carbon oxides (CO, CO2), nitrogen oxides (NO, NO2...).
Fire
Hazards in Presence of Various Substances:
Slightly
flammable to flammable in presence of heat. Non-flammable in presence of shocks.
Explosion
Hazards in Presence of Various Substances:
Slightly
explosive in presence of open flames and sparks. Non-explosive in presence of
shocks.
Fire
Fighting Media and Instructions: SMALL
FIRE: Use DRY chemical powder. LARGE FIRE: Use water spray, fog or foam. Do not
use water jet.

Remarks on Fire Hazards:
When
heated to decomposition it emits toxic fumes of nitrogen oxides, and bromides.
As with most organic solids, fire is possible at elevated temperatures
Special
Remarks on Explosion Hazards:
Fine
dust dispersed in air in sufficient concentrations, and in the presences of an
ignition source is a potential dust explosion hazard.
Section
6: Accidental Release Measures Small Spill:
Use
appropriate tools to put the spilled solid in a convenient waste disposal
container. Finish cleaning by spreading water on the contaminated surface and
dispose of according to local and regional authority requirements.
Large
Spill: Use a shovel to put
the material into a convenient waste disposal container. Finish cleaning by
spreading water on the contaminated surface and allow to evacuate through the
sanitary system.
Section

Keep
away from heat. Keep away from sources of ignition. Do not ingest. Do not
breathe dust. Wear suitable protective clothing. In case of insufficient
ventilation, wear suitable respiratory equipment. If ingested, seek medical
advice immediately and show the container or the label. Avoid contact with skin
and eyes. Keep away from incompatibles such as oxidizing agents.
Storage:
Keep container tightly
closed. Keep container in a cool, well-ventilated area.
Section
8: Exposure Controls/Personal Protection Engineering Controls:
Use
process enclosures, local exhaust ventilation, or other engineering controls to
keep airborne levels below recommended exposure limits. If user operations
generate dust, fume or mist, use ventilation to keep exposure to airborne
contaminants below the exposure limit.
Personal
Protection: Splash
goggles. Lab coat. Dust respirator. Be sure to use an approved/certified
respirator or equivalent. Gloves.
