SECTION 3 - HAZARDS IDENTIFICATION
Contact lenses should not be worn in the laboratory
Suspected Carcinogen-may produce cancer.
May be fatal if absorbed through the skin!
May be fatal if inhaled!
May be fatal if swallowed!
May be harmful if absorbed through the skin.
Absorption into the body leads to the formation of Methemoglobin which in sufficient concentration causes
cyanosis. Onset may be delayed 2 to 4 hours or longer.
May be rapidly absorbed through the skin with potential adverse health effects.
Can cause cyanosis.
Can cause delayed adverse health effects.
Dust and/or vapors can cause irritation to respiratory tract.
Can cause eye irritation.
Can be irritating to mucous membranes.
Repeated exposure to vapors and/or dust can cause eye injury.
Can cause blood disorders.
Possible mutagen-May cause birth defects in future generations.
Can cause skin irritation.
May be harmful if swallowed.
Possible cumulative poison.
Exposure can cause liver damage.
Prolonged exposure can cause severe skin irritation.
Can cause delayed lung injury.
Exposure can cause kidney damage.
Can cause cardiovascular system injury.
Exposure can cause nausea, headache dizziness and/or vomiting.
Can cause blood disorders.SECTION 4 - FIRST AID MEASURES
An antidote is a substance intended to counteract the effect of a poison. It should be
administered only by a physician or trained emergency personnel. Medical advice can be
