Exposure effects
   Ingestion
Harmful if swallowed. May cause irritation of the digestive tract. Low hazard for usual industrial handling. May be harmful if swallowed.
   Inhalation
Inhalation of high concentrations may cause central nervous system effects characterized by headache, dizziness, unconsciousness and coma. Causes respiratory tract irritation. Low hazard for usual industrial handling. May cause dizziness, incoordination, and unconsciousness. Central nervous system effects may include confusion, ataxia, vertigo, tinnitus, weakness, disorientation, lethargy, drowsiness, and finally coma. May be harmful if inhaled. May cause blood changes.
   Skin
Non-irritating to the skin. Causes severe skin irritation. May be absorbed through the skin. May cause severe irritation and possible burns.
   Eyes
Non-irritating to the eyes. Causes eye irritation. At high concentrations may cause lacrimation (tearing) and irritation.
