Section 3: Hazards Identification
Potential Acute Health Effects:
Extremely hazardous in case of ingestion, of inhalation. Very hazardous in
case of skin contact (irritant), of eye contact
(irritant). Hazardous in case of skin contact (corrosive, sensitizer,
permeator). Severe over-exposure can result in death.
Inflammation of the eye is characterized by redness, watering, and itching.
Skin inflammation is characterized by itching,
scaling, reddening, or, occasionally, blistering.
Potential Chronic Health Effects:
Extremely hazardous in case of ingestion, of inhalation. Very hazardous in
case of skin contact (irritant), of eye contact
(irritant). Hazardous in case of skin contact (corrosive, sensitizer,
permeator). CARCINOGENIC EFFECTS: Not available.
MUTAGENIC EFFECTS: Not available. TERATOGENIC EFFECTS: Not available.
DEVELOPMENTAL TOXICITY: Not
available. The substance is toxic to blood, kidneys, lungs, the nervous
system, liver, 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. Repeated or prolonged inhalation
of dust may lead to chronic respiratory irritation.

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:
If the chemical got onto the clothed portion of the body, remove the
contaminated clothes as quickly as possible, protecting
your own hands and body. Place the victim under a deluge shower. If the
chemical got on the victim's exposed skin, such
as the hands : Gently and thoroughly wash the contaminated skin with running
water and non-abrasive soap. Be particularly
careful to clean folds, crevices, creases and groin. 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. WARNING: It may
be hazardous to the person providing aid to give mouth-to-mouth resuscitation
when the inhaled material is toxic, infectious or
corrosive. Seek immediate 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 container dry. 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.
Never add water to this product 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:

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.
