3: Hazards Identification
Potential
Acute Health Effects:Hazardous
in case of skin contact (irritant), of eye contact (irritant), of ingestion, of
inhalation. Slightly hazardous in case of skin contact (sensitizer). Severe
over-exposure can result in death.
Potential
Chronic Health Effects:Slightly
hazardous in case of skin contact (sensitizer). CARCINOGENIC EFFECTS: Not
available. MUTAGENIC EFFECTS: Mutagenic for bacteria and/or yeast. TERATOGENIC
EFFECTS: Not available. DEVELOPMENTAL TOXICITY: Not available.
The
substance may be toxic to skin. Repeated or prolonged exposure to the substance
can produce target organs damage. Repeated exposure to a highly toxic material
may produce general deterioration of health by an accumulation in one or many
human organs.
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.

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.

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:Poisonous solid.
Stop leak if without risk. Do not get water inside container. Do not touch
spilled material. Use water spray to reduce vapors. Prevent entry into sewers,
basements or confined areas; dike if needed. Eliminate all ignition sources.
Call for assistance on disposal. 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. Ground all equipment
containing material. 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.
Personal
Protection in Case of a Large Spill:Splash
goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing
