Why is Fit Testing essential for respirator users?

Fit testing is essential for respirator users because it confirms that the respirator fits correctly and provides the necessary protection. A proper fit is critical because it ensures that the respirator forms a tight seal against the user's face, which prevents contaminated air from leaking in. If a respirator does not fit correctly, its effectiveness can be drastically reduced, increasing the risk of exposure to harmful substances.

Moreover, fit testing helps to identify the appropriate size and model of the respirator for each individual, catering to different facial shapes and sizes. This process not only contributes to the overall safety of the users but also enhances their comfort, which is important for ensuring compliance and consistent use in the workplace.
