FC § 504.4.7
To the maximum extent practicable, conduits, including cable trays, and piping, shall be installed at rooftop locations where they do not obstruct rooftop access landings, clear path or required clearances. If it is impracticable to avoid these areas, conduits and piping shall be designed and installed to facilitate access and minimize tripping hazards. Steps or ramps (or platforms with steps, ramps or ladders) shall be provided that are constructed of noncombustible material, equipped with railings, and designed to allow any conduit or piping installations that exceed 1 foot (305 mm) in height above the roof surface, or more than 24 inches (610 mm) in width, to be readily traversed. Steps, ramps, platforms and ladders shall not be placed in areas or in a manner that would obstruct any door or means of egress. All conduits and piping installations shall be color-coded with continuous, durable and weatherproof reflective or luminescent markings as follows, and for conduit and piping installed after July 1, 2014, shall be continuously labeled in an approved manner to indicate its contents: 1. High voltage wiring – Red.
2.Low voltage wiring – Orange.
3.Natural gas piping – Yellow.
4.Other compressed gas piping – Yellow, labeled at regular intervals with the type of gas.
5.Fuel oil piping – Yellow with black stripes.
