Group Protection
Overlapping protection provides coverage for a continuous hazard zone, with all TF1 nozzles at consistent
position (i.e. zone centerline), spacing, and height.
When there is an area within a hazard zone for which continuous overlapping coverage is not applicable,
the overlapping protection zone must be ended, and a new zone started for the new group of appliances.
Examples where continuous protection is interrupted, include a counter, storage or prep area, appliance
not requiring protection (e.g. enclosed oven) or an appliance requiring dedicated appliance coverage.
Refer to page 24 through page 26 for details of group overlapping protection.
Overlapping Protection
For hazard zones that include one or more deep fat fryers, the overlapping nozzles must be spaced no
more than 12" from each end of the appliance hazard zone and no more than 24" on center. All
overlapping nozzles must be located at the centerline of the 30” hazard zone (front to back), at the same
height, and aimed straight down. The nozzle height must be 40” to 45” above the appliance cooking
surface, except for woks, where height is measured from the inside bottom of the wok. The nozzles must
be positioned along the total hazard zone length to allow protection of each appliance in the hazard zone.
Overlapping Coverage - Group Protection
Overlapping protection provides coverage for a continuous hazard zone, with all nozzles at consistent
position (i.e., zone centerline), spacing, and height.
When there is an area within a hazard zone for which continuous overlapping coverage is not applicable,
the overlapping protection zone must be ended, and a new zone started for the new group of appliances.
Examples where continuous protection is interrupted, include a counter, storage or prep area, appliance
not requiring protection (e.g., enclosed oven) or an appliance requiring dedicated appliance coverage.
The examples on page 24 through page 26 provide details of group overlapping protection for interrupted
zones. This section illustrates the methodology for defining when a new hazard zone is required, as
described above. For specific overlapping coverage parameters (e.g., nozzle spacing and height
requirements).
