Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.

Chronic exposure to cyanide solutions may lead to the development of a 'cyanide' rash, characterized by itching, and by macular, papular, and vesicular eruptions, and may be accompanied by secondary infections.

Prolonged or repeated contact may cause skin necrosis and/or ulceration of the skin. Prolonged or repeated skin contact may cause dermatitis. Inhalation may result in symptoms similar to cyanide poisoning which include tachypnea, hyperpnea (abnormally rapid or deep breathing), and dyspnea (labored breathing) followed rapidly by respiratory depression. May cause effects similar to those described for ingestion. Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma. Large doses of cyanide may result in suddden loss of consciousness and prompt death small doses will prolong the above symptoms 1 to 2 hours. Human fatalities have been reported from acute poisoning. May cause tissue anoxia, characterized by weakness, headache, dizziness, confusion, cyanosis (bluish skin due to deficient oxygenation of the blood), weak and irregular heart beat, collapse, unconsciousness, convulsions, coma and death. Absorption into the body may cause cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood). Skin absorption may cause unconsciousness.

If absorbed, causes symptoms similar to those of ingestion.

Contact with skin causes irritation and possible burns, especially if the skin is wet or moist. May be absorbed through the skin in harmful amounts.
