What types of fit tests can be performed for SCBA?

The correct answer is the types of fit tests that can be performed for SCBA are qualitative and quantitative fit tests.

Qualitative fit testing is a pass/fail assessment that relies on the wearer’s response to a specific substance, such as a bitter or sweet tasting agent, to determine if the SCBA properly fits and effectively seals around the user's face. The test evaluates the seal based on subjective perception and is often quicker to administer than quantitative tests.

Quantitative fit testing, on the other hand, uses specialized equipment to measure the actual amount of leakage into the mask during different movements or activities. This type of test provides objective data regarding the performance of the SCBA seal and can offer a more precise evaluation of fit. It often involves the use of machines that quantify the concentration of particles in the air that gets in the mask compared to the concentration outside.

Both types of tests are essential components of a comprehensive SCBA fitting program, ensuring that firefighters and responders have equipment that provides a proper seal, which is critical for their safety in hazardous environments.

The other options mentioned, while related to some aspect of testing or assessment, do not specifically pertain to the standardized methods recognized for evaluating fit for SCBA equipment.
