The back-up alarm system must be inspected each workday at the beginning of each shift to ensure that it is audible, operating properly,
and securely attached to the vehicle. Inspect more often when: 1) The vehicle is operating in an adverse environment; 2) The vehicle is
operating in foul weather conditions; 3) The operator has reason to believe the alarm has been damaged or is not working properly; and/or
4) Increased background noise interferes with the ability of workers to recognize when the alarm is sounding.
