How often should airflow be checked for the PAPR system?

• A. Daily
• B. Weekly
• C. Only when new equipment
• D. Before each use

Answer: (D)

Airflow verification should be done before each use. This pre-use check confirms the blower is delivering the required flow, the battery is functioning, the filters are in place, and all connections are secure so you remain protected from contamination. A quick airflow check catches issues like a dead battery, a clogged filter, a kinked hose, or an alarm fault right away. Relying on only daily, weekly, or post–new-equipment checks leaves you vulnerable if a problem develops after the device has been stored or during routine use. Regular pre-use checks ensure the system is working correctly exactly when you need it.
