Section
3: Hazards Identification Potential Acute Health Effects:
Very
hazardous in case of skin contact (corrosive, irritant), of eye contact
(irritant), of ingestion, of inhalation. 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 over-exposure can produce lung damage, choking,
unconsciousness or death. Prolonged exposure may result in skin burns and
ulcerations. Over-exposure by inhalation may cause respiratory irritation.
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:
Very
hazardous in case of skin contact (corrosive, irritant), of eye contact
(irritant), of ingestion, of inhalation. CARCINOGENIC EFFECTS: Classified 1
(Known.) by NTP, + (PROVEN) by OSHA. Classified 2B (Possible for human.) by
IARC. ClassifiedA2 (Suspected for human.) by ACGIH. 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 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. 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 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.
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.

6: Accidental Release Measures
Small
Spill: Use appropriate
tools to put the spilled solid in a convenient waste disposal container.
Large
Spill: Oxidizing material.
Corrosive solid. Stop leak if without risk. Do not get water inside container.
Avoid contact with a combustible material (wood, paper, oil, clothing...). Keep
substance damp using water spray. Do not touch spilled material. Use water spray
to reduce vapors. Prevent entry into sewers, basements or confined areas; dike
if needed. 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 container dry. Keep away from heat. Keep away from sources of
ignition. Keep away from combustible material Do not breathe dust. Never add
water to this product In case of insufficient ventilation, wear suitable
respiratory equipment If you feel unwell, seek medical attention and show the
label when possible. Avoid contact with skin and eyes Storage: 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. Lab coat. 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
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: 0.05
(mg/m3)Consult local authorities for acceptable exposure limits.
