|Primary routes of entry:||Inhalation, ingestion, skin or eye contact (for dusts, mists, powder and fume)|
|Effects of overexposure:||No specific data, testing or information has been found for the chemical compounds that comprise this product. However, general comments are made below for the individual elements.|
|Carcinogenic assessment:||Cobalt - IARC 2B; Nickel - IARC 2B, NTP 2;|
Note: IARC 2B - The agent is possibly carcinogenic to humans. This category is generally used for agents for which there is limited evidence in humans in the absence of sufficient evidence in experimental animals. MSDS of tungsten heavy alloy may also be used when there is inadequate evidence of carcinogenicity in experimental animals.
NTP 2 - Substances or groups of substances which may reasonably be anticipated to be carcinogens. "Reasonably anticipated to be carcinogens" defines carcinogens for which there is limited evidence of carcinogenicity in humans and/or sufficient evidence of carcinogenicity in experimental animals.
