[F] 415.10.6 Piping and Tubing

2014 FBC - Building, 5th edition > 4 Special Detailed Requirements Based on Use and Occupancy > 415 Groups H-1, H-2, H-3, H-4 and H-5 > 415.10 Group H-5 > 415.10.6 Piping and Tubing
JUMP TO FULL CODE CHAPTER

Hazardous production materials piping and tubing shall comply with this section and ASME B31.3.

[F] 415.10.6.1 HPM Having a Health-Hazard Ranking of 3 or 4

Systems supplying HPM liquids or gases having a health-hazard ranking of 3 or 4 shall be welded throughout, except for connections, to the systems that are within a ventilated enclosure if the material is a gas, or an approved method of drainage or containment is provided for the connections if the material is a liquid.

[F] 415.10.6.2 Location in Service Corridors

Hazardous production materials supply piping or tubing in service corridors shall be exposed to view.

[F] 415.10.6.3 Excess Flow Control

Where HPM gases or liquids are carried in pressurized piping above 15 pounds per square inch gauge (psig) (103.4 kPa), excess flow control shall be provided. Where the piping originates from within a liquid storage room, HPM room or gas room, the excess flow control shall be located within the liquid storage room, HPM room or gas room. Where the piping originates from a bulk source, the excess flow control shall be located as close to the bulk source as practical.

[F] 415.10.6.4 Installations in Corridors and Above Other Occupancies

The installation of HPM piping and tubing within the space defined by the walls of corridors and the floor or roof above, or in concealed spaces above other occupancies, shall be in accordance with Sections 415.10.6.1 through 415.10.6.3 and the following conditions:

  1. Automatic sprinklers shall be installed within the space unless the space is less than 6 inches (152 mm) in the least dimension.
  2. Ventilation not less than six air changes per hour shall be provided. The space shall not be used to convey air from any other area.
  3. Where the piping or tubing is used to transport HPM liquids, a receptor shall be installed below such piping or tubing. The receptor shall be designed to collect any discharge or leakage and drain it to an approved location. The 1-hour enclosure shall not be used as part of the receptor.
  4. HPM supply piping and tubing and nonmetallic waste lines shall be separated from the corridor and from occupancies other than Group H-5 by fire barriers that have a fire-resistance rating of not less than 1 hour. Where gypsum wallboard is used, joints on the piping side of the enclosure are not required to be taped, provided the joints occur over framing members. Access openings into the enclosure shall be protected by approved fire protection-rated assemblies.
  5. Readily accessible manual or automatic remotely activated fail-safe emergency shutoff valves shall be installed on piping and tubing other than waste lines at the following locations:
    1. At branch connections into the fabrication area.
    2. At entries into corridors.
Exception: Transverse crossings of the corridors by supply piping that is enclosed within a ferrous pipe or tube for the width of the corridor need not comply with Items 1 through 5.

[F] 415.10.6.5 Identification

Piping, tubing and HPM waste lines shall be identified in accordance with ANSI A13.1 to indicate the material being transported.
