GHS hazard class · Health hazards

Carcinogenicity

Carcinogens are substances or mixtures that induce cancer or increase its incidence. The GHS has Category 1 (known or presumed human carcinogens, subdivided into 1A and 1B) and Category 2 (suspected human carcinogens).

What it means

Exposure may raise the risk of cancer, often after long or repeated exposure, with effects that can appear years later.

What to do

Obtain special instructions before use, do not handle until all safety precautions are understood, keep exposure as low as possible with engineering controls and protective equipment, and follow any workplace monitoring requirements.

This is general guidance for the class. Your product's safety data sheet takes precedence.
