The main components of a Self-Contained Breathing Apparatus (SCBA) include the face piece, back plate, air cylinder, and regulator.

The face piece serves as the interface between the user's face and the breathing apparatus, providing a sealed environment for inhalation of clean air while protecting the user from hazardous atmospheres. The back plate is the structural component that supports the weight of the SCBA and is designed to fit comfortably against the user's back. The air cylinder is a critical component, containing compressed air that supplies breathable oxygen to the user during operations, especially in environments where the air quality is compromised. The regulator controls the flow of air from the cylinder to the face piece, ensuring that the user receives an adequate supply of air at the right pressure.

These components work together to provide firefighters and emergency personnel with a reliable means of breathing in dangerous environments, making each one essential for the safety and effectiveness of the apparatus.
