The determination of the appropriate type of respiratory protective equipment (RPE) for a job is critically influenced by the amount and type of hazardous substances in the air. This factor is essential because different respiratory hazards necessitate specific types of protection.

For instance, if the air contains particulates, chemicals, or biological agents, the RPE must be capable of filtering or providing an adequate seal against those substances to ensure the worker's safety. The nature of the hazards, whether they are gases, vapors, or particulates, influences the design and functionality of the RPE, making it necessary to choose equipment that is specifically rated for those conditions.

While other factors, such as a worker's experience, the duration of exposure, and personal preference, play roles in the overall safety and comfort of using RPE, they do not have the same direct impact on determining the correct type of RPE needed for effective protection against identified hazards in the work environment.
