All firefighters who wear SCBA must be tested to determine proper fit of the face piece how often?

Firefighters who use Self-Contained Breathing Apparatus (SCBA) must undergo fit testing at least once a year to ensure the face piece is properly fitted. This annual testing is critical because the effectiveness of the SCBA relies on a tight seal with the firefighter's face. Changes in facial structure due to weight fluctuations, dental work, or growth can impact the fit and seal of the mask. By conducting the fit test annually, it ensures that any potential issues with fit can be addressed, thereby maintaining the safety and health of the firefighter during operations in hazardous environments. Regular fit testing adheres to OSHA regulations and industry best practices, which emphasize the importance of proper equipment fit in ensuring the efficacy of respiratory protection.
