Materials such as benzene, asbestos, and arsenic are:

Materials such as benzene, asbestos, and arsenic are:

• A. Carcinogens.
• B. Irritants.
• C. Convulsants.
• D. Corrosives.

Answer: (A)

Carcinogenic potential is the concept being tested. Benzene, asbestos, and arsenic are known to increase cancer risk with sufficient exposure, so they are classified as carcinogens. This means regulatory and health authorities recognize a real link between these substances and cancers such as leukemia (benzene), mesothelioma and lung cancer (asbestos), and various cancers (arsenic). Because of that cancer risk, they require strict controls to limit exposure, including engineering controls, monitoring, and appropriate protective equipment. While these materials can cause other health effects—benzene harming bone marrow, asbestos causing lung disease in addition to cancer, and arsenic affecting skin and other organs—the defining hazard used for safety decisions is their carcinogenic potential. They aren’t primarily described as corrosives, convulsants, or generic irritants in typical hazard classifications.
