To ensure proper functioning of the SCBA, one should always watch which indicators for leaks?

Monitoring indicators for leaks is crucial for the safe operation of the SCBA. Each of the listed options plays a significant role in assessing the integrity of the system.

The pressure gauge is essential, as it provides real-time information on the air supply within the tank. A drop in pressure indicates a possible leak, ensuring that the user is aware of any potential loss of breathable air.

The control module serves as the central information hub for the SCBA, offering alerts and notifications regarding the unit’s operational status. This includes monitoring for leaks, malfunctions, or other concerns that may affect performance.

The Head's Up Display (HUD) offers a visual representation of the SCBA's air supply and operating status. Any abnormalities in the HUD readings may signal a leak, allowing the user to take preventative measures.

Given that each of these indicators contributes significantly to identifying leaks and ensuring the SCBA operates correctly, it is necessary to check all of them. This comprehensive monitoring approach enhances safety and ensures that the SCBA functions effectively in hazardous environments.
