3: Hazards Identification
Potential
Acute Health Effects:
Very
hazardous in case of eye contact (irritant), of ingestion, . Hazardous in case
of skin contact (irritant), of inhalation (lung irritant). Slightly hazardous in
case of skin contact (permeator). Corrosive to eyes and skin. 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.
Severe over-exposure can produce lung damage, choking, unconsciousness or death.
Inflammation of the eye
is
characterized by redness, watering, and itching.
Potential
Chronic Health Effects:
CARCINOGENIC
EFFECTS: Not available. MUTAGENIC EFFECTS: Mutagenic for mammalian somatic
cells.
TERATOGENIC
EFFECTS: Not available. DEVELOPMENTAL TOXICITY: Not available. The substance may
be toxic to kidneys, lungs. 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 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. Cover the irritated skin
with an emollient. Remove contaminated clothing and shoes. Cold water may be
used.Wash clothing before reuse. Thoroughly clean shoes before reuse. Get
medical attention.
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. 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 unless directed to do so by medical personnel. Never give
anything by mouth to an unconscious person. If large quantities of this material
are swallowed, call a physician immediately. Loosen tight clothing such as a
collar, tie, belt or waistband.
Serious
Ingestion: Not available.
