3: Hazards Identification Potential Acute Health Effects:
Very
hazardous in case of ingestion. Hazardous in case of eye contact (irritant), of
inhalation. Slightly hazardous in case of skin contact (irritant, permeator).
Severe over-exposure can result in death.
Potential
Chronic Health Effects:
CARCINOGENIC
EFFECTS: A4 (Not classifiable for human or animal.) by ACGIH. MUTAGENIC EFFECTS:
Not available. TERATOGENIC EFFECTS: Not available. DEVELOPMENTAL TOXICITY:
Classified Development toxin [POSSIBLE]. The substance is toxic to blood,
kidneys, the nervous system, the reproductive system, liver, mucous membranes,
gastrointestinal tract, upper respiratory tract, central nervous system (CNS).
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. Wash contaminated clothing before reusing.
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. 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.

Small
Spill: Use appropriate
tools to put the spilled solid in a convenient waste disposal container.
Large
Spill: Flammable solid.
Stop leak if without risk. Do not touch spilled material. Use water spray
curtain to divert vapor drift. Prevent entry into sewers, basements or confined
areas; dike if needed. Eliminate all ignition sources. Call for assistance on
disposal. Be careful that the product is not present at a concentration level
above TLV. Check TLV on the MSDS and with local
authorities.
Section
7: Handling and Storage Precautions:
Keep
locked up Keep away from heat. Keep away from sources of ignition. Ground all
equipment containing material. 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. Keep away from incompatibles such as
oxidizing agents.
Storage:Flammable
materials should be stored in a separate safety storage cabinet or room. Keep
away from heat. Keep away from sources of ignition. Keep container tightly
closed. Keep in a cool, well-ventilated place. Ground all equipment containing
material. Keep container dry. Keep in a cool place.
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.
