Section
3: Hazards Identification Potential Acute Health Effects:
Extremely
hazardous in case of skin contact (corrosive, irritant), of eye contact
(irritant), of ingestion, of inhalation. Very hazardous in case of skin contact
(sensitizer, permeator). The amount of tissue damage depends on length of
contact. Eye contact can result in corneal damage or blindness. Skin contact can
produce inflammation and blistering. Inhalation of dust will produce irritation
to gastro-intestinal or respiratory tract, characterized by burning, sneezing
and coughing. Severe overexposure
can
produce lung damage, choking, unconsciousness or death. Inflammation of the eye
is haracterized 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 skin contact (corrosive, irritant), of eye contact
(irritant), of ingestion, of inhalation. Very hazardous in case of skin contact
(sensitizer, permeator). 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 of the eyes to a low level of dust can produce eye irritation. Repeated
skin exposure can produce local skin destruction, or dermatitis. Repeated
inhalation of dust can produce varying degree of respiratory irritation or lung
damage. 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. 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: 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. Cold water may be used. If irritation persists, seek medical ttention.
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.

concentration level above TLV. Check TLV on the MSDS and with local authorities.
Section
7: Handling and Storage Precautions:
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:
Keep container dry. Keep
in a cool place. Ground all equipment containing material. Corrosive materials
should be stored in a separate 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. Synthetic apron. Vapor and 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. Vapor and dust respirator. Boots. Gloves. A self contained
