Having a face fit test for workers using respiratory protective equipment (RPE) is essential primarily to ensure that the mask fits and functions correctly. A proper fit is crucial because an ill-fitting mask can lead to leaks that allow contaminants to enter the respiratory system, defeating the purpose of protection. The face fit test assesses the seal between the wearer's face and the mask to confirm that the equipment provides the necessary protection against harmful airborne substances.

While legal compliance and comfort may be factors in the overall selection and use of RPE, they do not directly address the primary concern of ensuring effective filtration and protection from hazardous environments. Comfort is important for long-term wear, but without a perfect fit, a mask—even if comfortable—can still fail to protect the wearer. Allergies to materials are relevant considerations but also do not have direct implications for the effective function of the RPE in the context of the fit test. So, the most significant reason for conducting a face fit test centers on the need for proper sealing and fit to ensure the effectiveness of respiratory protection.
