What is the primary purpose of using SCBA during firefighting operations?

The primary purpose of using Self-Contained Breathing Apparatus (SCBA) during firefighting operations is to protect against toxic smoke and gases. Fire environments often contain hazardous substances that can be harmful or fatal if inhaled. SCBAs provide breathable air from a tank, allowing firefighters to safely operate in smoke-filled and potentially dangerous atmospheres. This is critical in protecting their respiratory systems from toxic particles, chemicals, and various gases that are released during a fire.

While enhancing visibility might be a benefit in certain scenarios, it is not the primary function of the SCBA, as visibility is often impaired in smoke. Reducing weight carried is not a goal of SCBA usage; rather, they add additional weight due to the tank and equipment. Although SCBA can contribute to maintaining physical performance by allowing for safe breathing, the essential mandate remains focused on respiratory protection in environments filled with hazardous materials.
