Exposure effects
   Ingestion
Nausea and vomiting may occur. May produce methemoglobinemia in large quantities.
   Inhalation
May cause irritation.
   Skin
May cause irritation.
   Eyes
May cause irritation.

First aid
 
   Ingestion
Emesis: ipecac-induced vomiting is not recommended because of the potential for cns depression and seizures. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Oxygen - administer oxygen to all cyanotic or symptomatic patients. Methemoglobinemia: administer 1 to 2 mg/kg of 1% methylene blue slowly iv in symptomatic patients. Additional doses may be required. Shock and cardiac arrest - treat routinely. Adjunctive therapy - exchange transfusions and hyperbaric oxygen may be useful in severe cases.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
   Skin
Remove and isolate contaminated clothing and shoes. Flush with running water for at least 20 minutes.
   Eyes
Flush with running water for at least 20 minutes.
