Section
3: Hazards Identification
Potential
Acute Health Effects:Very
hazardous in case of skin contact (irritant), of eye contact (irritant).
Hazardous in case of ingestion, of inhalation. Slightly hazardous in case of
skin contact (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:CARCINOGENIC
EFFECTS: Not available. MUTAGENIC EFFECTS: Not available. TERATOGENIC EFFECTS:
Not available. DEVELOPMENTAL TOXICITY: Not available. 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. Cold water may be used.
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. Take
precautionary measures against electrostatic discharges. 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 Keep away from incompatibles such as metals.
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.
Exposure
Limits: TWA: 0.29 (mg/m3)
from ACGIHConsult local authorities for acceptable exposure limits.
