Which of the following is a known carcinogen commonly encountered in hazards materials work?

• A. Asbestos
• B. Water
• C. Salt
• D. Sugar

Answer: (A)

Asbestos is a known carcinogen commonly encountered in hazards materials work. Exposure to asbestos fibers, especially when inhaled, can lead to serious cancers such as mesothelioma and lung cancer. This is why asbestos stands out as the correct choice for a substance you might encounter in the field and need to recognize as a cancer risk. Water, salt, and sugar are not classified as carcinogens in typical HazMat awareness contexts; they’re common non-carcinogenic substances and don’t carry the same cancer risk in routine handling. The focus here is identifying the substance with established carcinogenic potential that workers must treat as a high-priority hazard.
