Section
3: Hazards Identification
Potential
Acute Health Effects:
Very
hazardous in case of eye contact (irritant), of ingestion, of inhalation.
Hazardous in case of skin contact (irritant). Severe over-exposure can result in
death. Inflammation of the eye is characterized by redness, watering, and
itching.
Potential
Chronic Health Effects:
Very
hazardous in case of eye contact (irritant), of ingestion, of inhalation.
Hazardous in case of skin contact (irritant).
CARCINOGENIC
EFFECTS: Not available. MUTAGENIC EFFECTS: Not available. TERATOGENIC EFFECTS:
Not available. DEVELOPMENTAL TOXICITY: Not available. The substance is toxic to
lungs. 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. 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. 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
locked up 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. 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
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. 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.
