True or False: The hazards of worker exposure are the most important consideration in respirator selection.

Worker exposure hazards are indeed the most crucial factor in respirator selection because the primary purpose of a respirator is to protect the health and safety of workers by filtering out harmful particulates, gases, and vapors from the air they breathe. The characteristics of the contaminants present in the workplace, including their concentration, toxicity, and the duration of exposure, directly inform the type of respirator to be used.

Selecting a respirator based on the specific hazards ensures that it provides adequate protection according to the nature of the exposure risk. For instance, different contaminants may require different types of filters, and the level of respiratory protection must match the exposure levels to comply with safety regulations and protect worker health. Overall, understanding the hazards helps in identifying the right type of respirator to maintain safety standards in occupational environments.
