PASS device is an acronym for the Personal Alert Safety System, a one-way communications device used by firefighters entering a building to alert the outside Rapid Entry Team (Also known as a RIT, or Rapid Intervention Team), that the wearer of the PASS device is in trouble and in need of rescue.
The PASS device is activated using airpressure from the SCBA equipment. Some older styles may be activated after a preset amount of time without movement from the firefighter. This is typically less than 5 minutes. The device creates a high pitched squealing sound, which is easily heard by fellow firefighters. These style devices are powered by a 9 volt battery, and are easily turned on using gloves.
PASS can also mean a term when using fire extinguishers. Remember to Pull, Aim, Squeeze, Spray when operating an extinguisher during a fire.
PASSdevices will be located on the SCBA waist belt, on the left side, back several inches from the waist belt snap for all SCBA's manufactured by other companies.
Whenever a PASSdevice is found to be malfunctioning, the device and the SCBA harness it is attached to shall be removed from service.
The PASSdevice may be manually activated by a fire fighter in distress by placing the control knob in the "ON" position.
