Why is fit testing essential in a Respiratory Protection Program?

• A. To verify the respirator battery life.
• B. To ensure comfort only.
• C. To ensure the respirator forms a proper seal on the user’s face, maximizing protection.
• D. To test color of respirator.

Answer: (C)

A proper seal on the face is essential for a respirator to provide protection. The filter can only work if air is drawn through the filter material rather than leaking around the edges of the facepiece. Fit testing checks that the chosen respirator model and size can form a tight seal on the individual’s face, and that this seal can be maintained during typical movements. If the seal leaks, contaminants bypass the filter and the level of protection drops significantly, even with a good filter. Fit testing is needed when selecting a respirator and whenever facial features change or a different model/size is used. It’s not about battery life, comfort alone, or color.
