How long will a PASS device remain motionless before sounding a warning tone?

• A. 10 seconds
• B. 40 seconds
• C. 30 seconds
• D. 20 seconds

Answer: (C)

A Personal Alert Safety System (PASS) device is designed to enhance firefighter safety by alerting others when a firefighter is motionless for a certain period, which may indicate a loss of consciousness or incapacitation. The PASS device will typically begin to emit a warning tone after it detects that the user has been motionless for 30 seconds. This time frame allows for a brief period of inactivity that might occur during normal operations while still ensuring a quick response if a firefighter is in distress. After the initial warning, the device usually escalates the alert to a louder alarm if motion is not detected, thereby helping to locate a downed firefighter more efficiently.
