When the system pressure falls below which psi should the control module be turned off?

The control module should be turned off when the system pressure falls below 200 psi to ensure the safety and functionality of the self-contained breathing apparatus (SCBA). This pressure threshold is critical because it signifies that the air supply is becoming insufficient for safe operation. At pressures below this mark, the effectiveness of the SCBA can be compromised, which could lead to inadequate oxygen supply in hazardous environments. By turning off the control module at this level, you help prevent any potential malfunctions or risks associated with operating outside of safe pressure limits. Additionally, maintaining the SCBA in optimal working conditions is essential for both user safety and equipment longevity.
