   (a)   Scope. This section sets forth standards, requirements and procedures for the storage, handling and use of carbon dioxide, in gaseous or liquid form.
   (b)   General Provisions.
      (1)   Applicability. Carbon dioxide containers and systems shall be designed, installed, operated and maintained in compliance with the requirements of FC Chapter 30, this section, and as to matters not specifically set forth in the Fire Code or this section, Compressed Gas Association standards CGA G-6-1984 and G-6.1-1986. The provisions of this section shall not apply to the storage, handling and use of carbon dioxide in any refrigerating system, or to any portable carbon dioxide fire extinguisher or carbon dioxide fire extinguishing system, except as provided in R3004-01(d)(2).
      (2)   Periodic inspections.
            (A)   Stationary containers and ancillary equipment shall be maintained in good working order, and visually inspected not less than once a month by the certificate of fitness holder.
            (B)   An inspection tag shall be affixed to every carbon dioxide container to document the following information:
(1)  the date of the inspection;
(2)  whether the system is in good working order; and
(3)  the name and certificate number of the certificate of fitness holder that performed the inspection.
   (c)   Design and Installation Requirements.
      (1)   Installation standard. Carbon dioxide systems shall be installed in accordance with the Building Code (including floor load limitation, wall piercing requirement or any other requirement affecting the integrity of a building member), Mechanical Code (including any ventilation requirements), Compressed Gas Association standards CGA G-6-1984 and G-6.1-1986, and the equipment manufacturer's design specifications and instructions.
      (2)   Overfill prevention. Automatic or approved manual means of preventing overfilling of the container shall be provided.
      (3)   Fill connections.
            (A)   Separate fill connections. Each low pressure stationary container shall have its own fill connection and related piping.
            (B)   Location.
(1)  The fill connection shall be located so as not to impede means of egress or the operation of sidewalk cellar entrance doors, including during the delivery process.
(2)  Fill connections shall be located outdoors, at least three (3) feet from the hinged side of any door.
      (4)   Piping systems.
            (A)   Type of piping. Piping, hose, fittings and other equipment that comes in contact with carbon dioxide shall be metallic, certified by the manufacturer as suitable for carbon dioxide use and for the operating temperature and maximum operating pressure of the carbon dioxide system. For soda carbonation installations, the hose from the dispenser regulator to the dispenser may be nonmetallic, provided the operating pressure is less than 125 psig.
            (B)   Fill and vent line design temperatures. Fill and vent lines shall be hard piped and designed to withstand a temperature of minus 110°F.
            (C)   Type of valves, pressure regulators, and pressure relief valves. Valves, pressure regulators and pressure relief devices shall be suitable for carbon dioxide use and rated for the operating temperature and maximum operating pressure of the carbon dioxide system.
            (D)   Piping pressure relief valves. Where liquid carbon dioxide can become trapped in the piping, pressure relief devices shall be provided. Pressure relief valves and vent lines from pressure relief valves shall not be provided with shut off valves or other obstructions which could render such valves inoperable. Pressure relief devices shall discharge in a manner designed to prevent harm to the public or delivery person.
            (E)   Container pressure relief valves. Every container which contains more than 60 pounds of carbon dioxide shall have its container pressure relief valves discharge outdoors. Every pressure relief valve protecting piping shall discharge outdoors. The soda carbonation dispensing pressure regulator relief valve is not required to discharge outdoors.
            (F)   Vent line pressure relief valves. Vent lines from pressure relief valves shall be of such a size, length and arrangement so as not to interfere with the proper operation of the valves. The size of the vents of pressure relief devices shall be equal or larger in size than the pressure relief device outlet size.
            (G)   Soda carbonation regulators. For soda carbonation installations, the dispenser pressure regulator shall be designed to fail in the closed position.
            (H)   Supports and protection. Piping shall be securely supported and braced, and installed with due allowance for thermal expansion and contraction. Expansion joints shall not be used. Piping shall be protected from physical damage.
            (I)   Insulation. Insulation for carbon dioxide containers and ancillary equipment shall be of a noncombustible material.
   (d)   Operational Requirements.
      (1)   Filling of containers.
            (A)   Filling limits and restrictions.
(1)  It shall be unlawful to fill high-pressure carbon dioxide containers from a cargo tank.
(2)  Each low pressure carbon dioxide container, as defined in CGA Standard G-6.1-1986, shall not be filled to exceed 90 percent of its volumetric capacity at the maximum allowable working pressure of the container.
      (2)   Supervision. The filling of a carbon dioxide container from any source shall be performed under the personal supervision of a certificate of fitness holder.
      (3)   Installation acceptance testing. The piping system shall be pressure tested for leaks upon installation. The test is successful if there are no leaks when a test pressure of not less than 100 percent of the normal operating pressure is maintained for a period of time necessary to detect any leak, but in no case for less than one half hour.
      (4)   Periodic testing and recordkeeping. The piping system shall be retested for leaks at least once every ten (10) years, or upon order of the Department. The piping system shall not be subjected to a pressure that exceeds its maximum allowable working pressure.
      (5)   Cargo tank deliveries. Carbon dioxide containers shall be filled from cargo tanks in compliance with the following requirements:
            (A)   the container shall not be subjected to a pressure that exceeds its maximum allowable working pressure; and
            (B)   the piping system shall not be subjected to a pressure that exceeds its maximum allowable working pressure.
      (6)   Notification of leaks. The owner or operator of any carbon dioxide system who becomes aware of any leak from the container or ancillary equipment, or other indication that the system is not in good working order, shall promptly notify the certificate of fitness holder. Such system shall be promptly restored to good working order.
      (7)   Storage room signage required. Warning signs shall be conspicuously posted at all entrances to any room in which a carbon dioxide container is located stating, reading "WARNING: CARBON DIOXIDE STORAGE. CARE MUST BE TAKEN TO AVOID SUFFOCATION AND ASPHYXIATION."
      (8)   Fill connection signage. Fill connections shall have a label affixed indicating the maximum allowable working pressure of the system.
   (a)   Scope. This section sets forth the design, installation, operation and maintenance requirements for the storage, handling and use of anhydrous ammonia.
   (b)   General Provisions. Anhydrous ammonia containers and systems shall be designed, installed, operated and maintained in compliance with the requirements of FC Chapter 30, this section, and as to matters not specifically set forth in the Fire Code or this section, Compressed Gas Association's Standard G-2 (8th edition). The provisions of this section shall not apply to the storage, handling and use of anhydrous ammonia in any refrigerating system.
