by route(s) of administration, at site(s), of histologic type(s), or by mechanism(s) not considered

relevant to worker exposure. Available epidemologic studies do not confirm an increased risk of

cancer in exposed humans.Available evidence suggests that the agent is not likely to cause cancer in humans except under

uncommon or unlikely routes or levels of exposure.
