(f) Design and Installation Requirements.
(1) Natural gas piping and control valves. In connection with the use of portable space heaters fueled by piped natural gas at construction sites:
(A) Temporary natural gas piping shall comply with all requirements of the construction codes.
(B) Temporary natural gas piping shall be installed in such a manner and at such locations as will minimize the risk of damage from the construction activity occurring at the construction site.
(C) Temporary natural gas piping shall be clearly marked "Natural Gas" at least once every 30 feet, and at least once in each room or other separate area.
