V        HEALTH HAZARD INFORMATION



Toxicity Data: None

Route(s) of Entry: Inhalation



Effects of Over Exposure:



Inhalation: In general nickel compounds are respiratory irritants and can cause pneumonitis if the exposure is severe. Certain

individuals may develop respiratory sensitivity to nickel characterized by asthma-like symptoms.



Dermal: Mild irritant to the skin and eye. Repeated skin contact with nickel can cause a form of dermatitis (nickel itch).

Other: Both nickel and silicon have relatively low oral toxicity.



Carcinogenicity: Ni NTP? Yes                 IARC Monographs? Yes



EMERGENCY AND FIRST AID PROCEDURES:



EYE: Flush with plenty of water for at least 15 minutes.

SKIN: Flush with soap and water.

INHALATION: Remove to fresh air. Seek medical attention.

INGESTION: Induce vomiting. Seek medical attention.
