What is the correct breathing technique when using SCBA?

The correct breathing technique when using a Self-Contained Breathing Apparatus (SCBA) is to take a short, partial breath, hold it briefly, and then slowly exhale. This method helps to conserve air within the SCBA tank while still ensuring that the user is adequately ventilating their lungs. When wearing an SCBA, especially in environments where visibility is poor or where stress levels may be heightened, it's important to manage air consumption efficiently. Taking short breaths can also aid in maintaining calmness and reducing the feeling of panic that may occur in high-stress situations, making it easier for firefighters to function effectively.

Using this technique allows for a balance between air supply conservation and ensuring that the body receives enough oxygen to perform necessary tasks. Holding the breath before exhaling further helps by minimizing the amount of air wasted through rapid or shallow breathing. Proper training on SCBA use emphasizes the importance of these techniques to optimize performance and safety in emergency situations.
