w. For dry systems use belt-less and oil-less air compressors.

x. All fire sprinkler systems shall have line pressure gauges at riser for each system.

y. In new construction facilities, locate fire sprinkler risers in a separate riser room or mechanical room both having direct access from the exterior of the building, and located so it is accessible to DPW without entering secured areas. In renovation projects, locating a sprinkler riser inside a riser room is preferred, if the sprinkler riser is located in the open area of the building it must be enclosed inside a lockable cage to protect it from damage and tampering.

Bollards may also be necessary in warehouse facilities.
