lungs, the nervous system, mucous membranes. Repeated or prolonged exposure to
the substance can produce target organs damage.
Section
4: First Aid Measures Eye Contact:
Check
for and remove any contact lenses. Immediately flush eyes with running water for
at least 15 minutes, keeping eyelids open. Cold water may be used. Do not use an
eye ointment. Seek medical attention.
Skin
Contact: After contact
with skin, wash immediately with plenty of water. Gently and thoroughly wash the
contaminated skin with running water and non-abrasive soap. Be particularly
careful to clean folds, crevices, creases and groin. Cold water may be used.
Cover the irritated skin with an emollient. If irritation persists, seek medical
attention. Wash contaminated clothing before reusing.
Serious
Skin Contact: Wash with a
disinfectant soap and cover the contaminated skin with an anti-bacterial cream.
Seek immediate medical attention.
Inhalation:
Allow the victim to rest
in a well ventilated area. Seek immediate medical attention.
Serious
Inhalation: Evacuate the
victim to a safe area as soon as possible. Loosen tight clothing such as a
collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If
the victim is not breathing, perform mouth-to-mouth resuscitation. Seek medical
attention.
Ingestion:
Do
not induce vomiting. Examine the lips and mouth to ascertain whether the tissues
are damaged, a possible indication that the toxic material was ingested; the
absence of such signs, however, is not conclusive. Loosen tight clothing such as
a collar, tie, belt or waistband. If the victim is not breathing, perform
mouth-to-mouth resuscitation. Seek immediate medical attention.
Serious
Ingestion: Not available.

Section
7: Handling and Storage Precautions:
Keep
away from heat. Keep away from sources of ignition. Empty containers pose a fire
risk, evaporate the residue under a fume hood. 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, alkalis.
Storage:
Keep container dry. Keep in a cool place. Ground all equipment
containing material. Keep container tightly closed. Keep in a cool,
well-ventilated place. Combustible materials should be stored away from extreme
heat and away from strong oxidizing
agents.
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.
