Breathing through air-purifying (AP) respirators (such as disposable masks and canister respirators) poses a small load to the respiratory system, and most persons capable of the job demands without using a respirator will be capable of using these types of respirators. A medical fitness assessment typically consists of a short respiratory health questionnaire, followed by respirator fit testing by safety specialists or industrial hygienists. A physician assessment and lung function testing (spirometry) may be required for workers with current respiratory conditions.
Supplied-air (SA) and self-contained breathing apparatus (SCBA) are required for more hazardous work environments, and can pose medium physical demands. Medical assessments will typically include a more detailed respiratory health questionnaire and lung function testing (spirometry), followed by respirator fit testing by safety specialists or industrial hygienists. A physician assessment may be required for workers with current respiratory conditions.
