Exposure effects
Increased temperature may be noted in some cases. Abnormally low blood pressure may occur. Mental status may be depressed. Acute exposure - neurologic: central nervous system depression can occur following exposure. Coma and muscle contractions may be present with severe intoxication.
   Ingestion
Gastroenteritis with vomiting may occur after ingestion of some copper salts. Mucosal erosions, a metallic taste, burning epigastric sensation and diarrhea may also occur.
   Inhalation
Metal fume fever, wheezing and rales have been reported in workers exposed to fine copper dust. Dyspnea has developed after oral copper exposure. Pulmonary edema and alveolar inflammation have been noted in animals.
   Skin
Skin exposure can produce in severe irritation, itching, erythema, dermatitis and eczema; systemic toxicity may result.

First aid
 
   Ingestion
Following ingestion and/or prior to gastric evacuation, immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 15 ml/kg in a child). Vomiting is rapid and spontaneous in most patients following ingestion of copper salts. Ipecac is contraindicated after ingestion of caustic copper salts because of the risk of further injury to the gastrointestinal mucosa and the possibility of severe cns changes.
   Inhalation
Remove from exposure.
   Skin
Remove contaminated clothing. Wash exposed area with soap and water. If symptoms persist, seek medical attention. Launder clothing before reuse.
   Eyes
