3: Hazards Identification
Potential
Acute Health Effects:
Very
hazardous in case of skin contact (irritant, permeator), of eye contact
(irritant), of ingestion, . Hazardous in case of skin contact (corrosive,
sensitizer), of eye contact (corrosive), of inhalation (lung irritant). 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, 1 (Proven for human.) by
IARC. MUTAGENIC EFFECTS: Mutagenic for mammalian somatic cells. Mutagenic for
bacteria and/or yeast. TERATOGENIC EFFECTS: Not available. DEVELOPMENTAL
TOXICITY: Not available. The substance may be toxic to blood, kidneys, liver,
upper respiratory tract. 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 immediately.
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:If
swallowed, do not induce vomiting unless directed to do so by medical personnel.
Never give anything by mouth to an unconscious person. Loosen tight clothing
such as a collar, tie, belt or waistband. Get medical attention immediately.
Serious
Ingestion: Not available.

Section
7: Handling and Storage
Precautions:
Keep
container dry. Do not ingest. Do not breathe dust. Never add water to this
product. 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 combustible materials, organic materials.
