What is the main purpose of an SCBA?

The main purpose of a Self-Contained Breathing Apparatus (SCBA) is to supply breathable air to the wearer. This is particularly crucial in firefighting and rescue situations where the atmosphere may be filled with smoke, toxic gases, or low oxygen levels. The SCBA creates a safe environment by providing a continuous flow of clean, breathable air, allowing firefighters to perform their duties effectively without being hindered by the hazardous conditions present.

This function is vital as it enables firefighters to enter and operate in environments where visibility may be compromised due to smoke or where the air quality is unsafe for normal breathing. As a result, the SCBA is a critical piece of safety equipment that directly impacts the safety and effectiveness of firefighting operations.
