How often must personnel be fit tested according to CAL FIRE guidelines?

Personnel must be fit tested annually according to CAL FIRE guidelines to ensure that their personal protective equipment, particularly respiratory protection, fits properly and works effectively. This annual fit testing is crucial in maintaining safety standards for firefighters, as it confirms that masks and other respiratory devices create a proper seal, thus maximizing the users' protection against hazardous environments. Regular fit testing helps to identify any changes in the individual's physical condition, like weight fluctuations or changes in facial structure, which could affect the proper functioning of their protective gear. This proactive approach helps to minimize health risks associated with smoke, toxic gases, and other hazardous materials encountered during firefighting operations. Regular testing ensures that personnel are prepared and safe on the job, reinforcing the importance of adhering to CAL FIRE's safety protocols.
