Section
3: Hazards Identification
Potential
Acute Health Effects:Very hazardous in case
of skin contact (irritant), of eye contact (irritant), of ingestion, of
inhalation. 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: 3 (Not classifiable for human.) by IARC. MUTAGENIC EFFECTS: Mutagenic
for mammalian somatic cells. Mutagenic for bacteria and/or yeast. TERATOGENIC
EFFECTS: Classified POSSIBLE for human.
DEVELOPMENTAL
TOXICITY: Classified Reproductive system/toxin/female, Reproductive
system/toxin/male [POSSIBLE].
The
substance may be toxic to blood, kidneys, liver, skin, central nervous system
(CNS). Repeated or prolonged exposure to the substance can produce target organs
damage. Repeated exposure to a 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. In case of contact, immediately flush eyes with plenty of water for at
least 15 minutes. Cold water may be used. Get medical attention immediately.
Skin
Contact:In case of contact, immediately
flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Cover the irritated skin with an emollient.
Cold water may be used.Wash clothing before reuse. Thoroughly clean shoes before
reuse. Get medical attention immediately.
Serious
Skin Contact:Wash with a disinfectant soap
and cover the contaminated skin with an anti-bacterial cream. Seek immediate
medical attention.
Inhalation:If
inhaled, remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get 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

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:
