Which step in choosing respiratory equipment ensures the device performs its intended function?

• A. Determine Hazard
• B. Select equipment approved for function
• C. Assure device performs intended function
• D. Check fit

Answer: (C)

The main idea here is making sure the device actually works as it’s supposed to. After you’ve identified the hazard and chosen equipment that is approved for that function, and after you’ve checked that the wearer can use it correctly, you still need to verify that the device performs its intended protection in real conditions. This means performing the appropriate functional tests and checks to confirm the equipment delivers the rated protection—things like validating airflow or filter performance, confirming alarms or battery systems work, and ensuring the device operates properly under expected use. If you only determine the hazard, pick an approved device, or check fit, you haven’t proven the device will actually perform when used. Verifying performance ties the selection to real-world function, giving you confidence that the protection will hold up during use.
