Question

select the choice that best completes the following statement.
asbestos can be categorized as:
a) oxygen deficiency hazard
b) electrical hazard
c) harmful dust hazard
d) chemical hazard

Explanation:

Asbestos is a mineral composed of thin, needle - like fibers. When these fibers are released into the air (for example, during construction or demolition of old buildings with asbestos - containing materials), they can be inhaled. Inhaled asbestos fibers can cause serious health problems such as lung cancer, mesothelioma, and asbestosis. Since it is a dust (in the form of fibers) that is harmful to human health when inhaled, it is categorized as a harmful dust hazard.
Oxygen deficiency hazard is related to a lack of oxygen in an environment (e.g., in a confined space with a gas displacing oxygen). Electrical hazard is related to electricity (e.g., faulty wiring, exposed electrical parts). Chemical hazard is a broader category, but asbestos is specifically a dust - related hazard rather than a general chemical (like a liquid or gas chemical).

Answer:

C. Harmful dust hazard
