Exposure effects
Absorption into the body leads to the formation of methemoglobin which in sufficient concentrations causes cyanosis.
   Ingestion
Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause methemoglobinemia, cyanosis, convulsions, and death. Effects may be delayed 2 to 4 hours.
   Inhalation
Causes respiratory tract irritation. May cause methemoglobinemia, cyanosis, convulsions, tachycardia, dyspnea, and death. Damage may be delayed.
