What action should you perform when putting on your respirator?

When putting on your respirator, performing a seal check is crucial to ensure that the respirator is properly fitted to your face. This process verifies that there are no gaps between the respirator and your skin, which is necessary for the device to function effectively. A proper seal prevents airborne contaminants, such as asbestos fibers, from entering the respirator and being inhaled.

The seal check involves pressing the respirator lightly against the face and inhaling to see if the mask collapses slightly; this indicates a good seal. Conversely, if you feel air leaking in, it suggests that the respirator is not fitted correctly. This step is essential for your safety, as even small leaks can lead to a significant exposure risk.

While a pressure check, fit inspection, and breath test may relate to the overall maintenance and function of the respirator, they do not specifically address the critical immediate need to ensure a proper seal upon putting the respirator on. Thus, the seal check is the most appropriate action to take to ensure effective protection against hazardous airborne materials.
