The audible / visual alarm must be located where the delivery transfer operator can see and/or hear the alarm when it is generated.
Overfill alarm systems should be equipped with a “Test” or “Reset” button to verify the functionality of the audible and visual alarm components. Systems should be checked weekly for functionality.
Do you know where the overfill alarm is located at your facility? If not, you will need to identify the alarm device and take note of its location for future reference.
