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. Cold water may be used. 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. Cold water may be
used.Wash clothing before reuse. Thoroughly clean shoes before reuse. Get
medical attention.
Serious
Skin Contact:Wash with a
disinfectant soap and cover the contaminated skin with an anti-bacterial cream.
Seek immediate medical attention.
Inhalation:If
inhaled, remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical attention.
Serious
Inhalation: Not available.
Ingestion:Do
NOT induce vomiting unless directed to do so by medical personnel. Never give
anything by mouth to an unconscious person. If large quantities of this material
are swallowed, call a physician immediately. Loosen tight clothing such as a
collar, tie, belt or waistband.

products are carbon oxides (CO, CO2).
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 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
7: Handling and Storage
Precautions: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, alkalis.
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.
Personal
Protection in Case of a Large Spill:Splash
goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing
apparatus should be used to avoid inhalation of the product. Suggested
protective clothing might not be sufficient; consult a specialist BEFORE
handling this product.
