Section 3: Hazards Identification
Potential Acute Health Effects:
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. 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.
Potential Chronic Health Effects:
CARCINOGENIC EFFECTS: Not available.
MUTAGENIC EFFECTS: Not available.
TERATOGENIC EFFECTS: Not available.
DEVELOPMENTAL TOXICITY: Not available.
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.
Section 4: First Aid Measures
Eye Contact:
Check for and remove any contact lenses. Immediately flush eyes with running water for at least 15 minutes,
keeping eyelids open. Cold water may be used. 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. Cold water may be used.
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.
