The pass device monitors which two statuses?

The correct answer, which identifies the statuses monitored by the PASS device, is relevant to the safety and functionality of a Self-Contained Breathing Apparatus (SCBA). The PASS device, or Personal Alert Safety System, is designed to provide alerts in emergency situations, particularly for firefighters and first responders.

Monitoring the battery status is crucial for ensuring that the PASS device is operational and able to send alarms when needed. A low battery could mean the device fails during an emergency, which could have dire consequences. Air pressure is equally important because it indicates the remaining air supply in the SCBA tank. If pressure levels drop too low, it signals the wearer that they may soon run out of breathable air, prompting timely action to exit the hazardous environment.

Understanding that the PASS device focuses on these two specific statuses is essential for maintaining safety protocols and ensuring readiness during operations where breathing apparatus is required. Thus, awareness of both the battery health and the air pressure is fundamental for effective use and support of emergency personnel in the field.
