Section III. Hazards Identification
Toxic if ingested or inhaled. Avoid prolonged contact with this material. Overexposure may result in serious illness or death.
Acute Health Effects
Corrosive to skin, eyes, and respiratory system. Liquid or spray mist may produce tissue damage, particularly in mucous
membranes of the eyes, mouth and respiratory tract. Skin contact may produce burns. Eye contact can result in corneal
damage or blindness. Inhalation of the spray mist may produce severe irritation of respiratory tract, characterized by
coughing, choking, or shortness of breath. Corrosive materials may cause serious injury if ingested.
Skin contact may result in sensitization. Always cover all exposed skin with an impermeable layer and use proper eye
protection. A OSHA/MSHA approved dust and vapor respirator is required when working with this material.
Follow safe industrial hygiene practices and always wear proper protective equipment when handling this compound.
CARCINOGENIC EFFECTS : Not available.
Chronic Health Effects
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. Repeated exposure to an highly toxic material may produce general deterioration of health by an accumulation in
one or many human organs.

and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
InhalationIf the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
improve.
IngestionDO 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. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible
indication that the toxic material was ingested; the absence of such signs, however, is not conclusive.
