If breathing becomes difficult through your SCSR, what should you do?

In situations where breathing becomes difficult through a Self-Contained Self-Rescuer (SCSR), it is crucial to maintain the integrity of the breathing system to ensure safety. The option of never removing the breathing hose emphasizes the importance of keeping the SCSR sealed and functional. Removing the hose could expose you to harmful environmental conditions where the SCSR is meant to protect against respiratory hazards.

Maintaining the connection of the breathing hose allows the device to continue providing oxygen and filtering out harmful gases. Disrupting this connection can lead to inhaling toxic air or reducing the effectiveness of the system, which could be life-threatening. Therefore, ensuring that the breathing hose remains in place is vital for personal safety in an emergency where the SCSR is in use.
