The main idea is to ensure the respirator actually protects the wearer by confirming a proper fit and full function before and during entry. Start with pre-entry fit testing to verify that the specific facepiece and size can provide an effective seal for the individual, given their facial features. Then, before each entry, perform a seal check to confirm the facepiece is seated correctly and there are no immediate leaks. Have the wearer confirm that the fit feels comfortable and secure, ensuring they can don the respirator correctly and consistently. Once inside, continuously monitor for comfort and proper function—check for any changes in seal integrity, breathing resistance, airflow through the respirator, and the condition of filters or cartridges. If the fit is compromised, the wearer experiences leakage, or the respirator isn’t functioning as intended, entry should be halted and the issue addressed.

Why this approach is best: it provides objective verification tailored to the individual, ensures a proper seal is achieved each time the device is worn, and maintains protection throughout the task by watching for changes that could degrade performance. Relying only on confidence, waiting until after an incident to assess fit, or neglecting ongoing checks would leave entrants vulnerable to exposure.
