Section
3: Hazards Identification
Potential
Acute Health Effects:Hazardous
in case of eye contact (irritant), of ingestion, of inhalation. Slightly
hazardous in case of skin contact (irritant). Severe over-exposure can result in
death.
Potential
Chronic Health Effects:CARCINOGENIC
EFFECTS: Not available. MUTAGENIC EFFECTS: Not available. TERATOGENIC EFFECTS:
Not available.
DEVELOPMENTAL
TOXICITY: Not available. The substance is toxic to lungs, mucous membranes.
Repeated or prolonged exposure to the substance can produce target organs
damage. Repeated exposure to an 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. 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. Cover the irritated skin
with an emollient. If irritation persists, seek medical attention.
Serious
Skin Contact: Not
available.
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.

7: Handling and Storage
Precautions:Keep
locked up Do not ingest. Do not breathe dust. Avoid contact with eyes 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.
Storage:Keep
container tightly closed. Keep in a cool, well-ventilated place. Highly toxic or
infectious materials should be stored in a separate locked safety storage
cabinet or room.
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.
Exposure
Limits:TWA: 5 CEIL: 10
(mg/m3) from ACGIH [1995] Consult local authorities for acceptable exposure
