3: Hazards Identification
Potential
Acute Health Effects:
Very
hazardous in case of skin contact (irritant, sensitizer), of eye contact
(irritant), of ingestion, . Hazardous in case of skin contact (corrosive,
permeator), of eye contact (corrosive), of inhalation (lung irritant). Prolonged
exposure may result in skin burns and ulcerations. Over-exposure by inhalation
may cause respiratory irritation. 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: Classified A1 (Confirmed for human.) by ACGIH. MUTAGENIC EFFECTS:
Mutagenic for bacteria and/or yeast. TERATOGENIC EFFECTS: Not available.
DEVELOPMENTAL TOXICITY: Not available. The substance may be toxic to kidneys,
liver, heart, upper respiratory tract. Repeated or prolonged exposure to the
substance can produce target organs damage. Repeated exposure to a highly toxic

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
