<br />shall include condirions where the container, cylinder or tank
<br />a�s is inclined as much as 45 degrees (0.80 rad) from the ver-
<br />tical.
<br />Exceptions:
<br />l. Co»zpressed gas containers with a water voluine less
<br />than 1.3 gallons (5 L) are allowed to be stored in a
<br />horizontal position.
<br />2. Cylinders, containers and tanks containing nonflam-
<br />mable gases or cylinders, containers and tanks con-
<br />taining nonliquefied flammable gases, which have
<br />been secured to a pallet for transportation purposes.
<br />5304.2 Material-specific regulations. In addition to the
<br />requirements of this section, indoor and outdoor storage of
<br />compressed gases shall comply with the material-specific
<br />provisions of Chapters 54, 58 and 60 through 67.
<br />SECTION 5305
<br />USE AND HANDLING OF COMPRESSED GASES
<br />5305.1 Compressed gas systems. Compressed gas systems
<br />shall be suitable for tl�e use intended and shall be designed by
<br />persons competent in such desigu. Compressed gas equip-
<br />ment, machinery and processes shall be listed or npprovecl.
<br />5305.2 Controls. Compressed gas systein controls shall be
<br />designed to prevent materials from entering or leaving pro-
<br />cess or reaction systems at other than the intended time, rate
<br />or path. Automatic controls shall be designed to be fail safe.
<br />5305.3 Piping systems. Piping, including tubing, valves, fit-
<br />tings and pressure regulators, shall comply with this section
<br />and Chapter 50. Piping, tubing, pressure regulators, valves
<br />and other apparatus shall be kept gas tight to prevent leakage.
<br />5305.4 Valves. Valves urilized on co�npressed gns systems
<br />shall be suitable for the use intended and shall be accessible.
<br />Valve handles or operators for required shutoff valves shall
<br />not be removed or otherwise altered to prevent access.
<br />5305.5 Venting. Venting of gases shall be directed to an
<br />approved location. Venting shall comply with the Interna-
<br />tional Mecl2anical Code.
<br />5305.6 Upright use. Compressed gas containers, cylinders
<br />and tanks, except those designed for use in a horizontal posi-
<br />tion, and all compressed gas containers, cylinders and tanks
<br />containing nonliquefied gases, shall be used in an upright
<br />position with the valve end up. An upright position shall
<br />include conditions where the container, cylinder or tank axis
<br />is inclined as much as 45 degrees (0.80 rad) from the vertical.
<br />Use of nonflammable liquefied gases in the inverted position
<br />when the liquid phase is used shall not be prohibited provided
<br />that the container, cylinder or tank is properly secured and the
<br />dispensinb apparatus is designed for liquefied gas use.
<br />Exception: Cor����ressed gas containers, cylinders and
<br />tanks with a water volume less than 1.3 gallons (5 L) are
<br />allowed to be used in a horizontal position.
<br />5305.7 Transfer. Transfer of gases between containers, cyl-
<br />inders and tanks shall be performed by qualified personnel
<br />• COMPRESSED GASES
<br />using equipment and operating procedures in accordance
<br />with CGA P-1.
<br />Exception: Fueling of vehicles with compressed natural
<br />gas (CNG).
<br />5305.� Use of compressed gas for inf7ation. Inflatable
<br />equipment, devices or balloons shall only be pressurized or
<br />filled with compressed air or inert gases.
<br />5305.9 Material-specific regulations. In addition to the
<br />requirements of this section, indoor ancl outcioor use of cor�i-
<br />pressed gases shall comply with the material-specific provi-
<br />sions of Chapters 54, 58 and 60 through 67.
<br />5305.10 Handling. The handling of co�npressed gas contain-
<br />ers, cylv�ders and tanks s11a11 comply with Sections 5305.10.1
<br />and 5305.10.2.
<br />5305.10.t Carts and trucks. Containers, cylinders and
<br />tanks shall be moved using an approved method. Where
<br />containers, cylinders or tanks are moved by hand cart,
<br />hand truck or other mobile device, sucl� carts, trucks or
<br />devices shall be designed for the secui•e inovement of con-
<br />tainers, cylinders or tanks. Carts and h-ucks utilized for
<br />transport of con2pressed gas containers, cylinders and
<br />tanks within buildings shall comply with Section 5003.10.
<br />Carts and trucks utilized for transport of compressed gas
<br />containers, cylinders and tanks exterior to buildings shall
<br />be designed so that the containers, cylinders and tanks will
<br />be secured against dropping or otherwise striking against
<br />each other or other surfaces.
<br />�305.10.2 Lifting devices. Ropes, chains or slings shall
<br />not be used to suspend cornpressed gas containers, cylin-
<br />ders and tanks unless provisions at time of manufacture
<br />h�ve been made on the container, cylinder or tank for
<br />appropriate lifting attachments, such as lligs.
<br />SECTION 5306
<br />MEDICAL GAS SYSTEMS
<br />5306.1 General. Co»�.pressed gases at hospitals and similar
<br />facilities intended for inhalaCion or sedation including, but not
<br />limited to, analgesia systems for dentistry, podiatry, veteri-
<br />�1ary and similar uses shall coinply with Sections 5306.2
<br />through 5306.4 in addition to other requirements of this chap-
<br />ter.
<br />5306.2 Interior supply location. Medical gases shall be
<br />stored in areas dedicated to the storage of such gases without
<br />other storage or uses. Where containers of inedical gases in
<br />quantities greater than the permit amount are located inside
<br />buildings, they shall be in a 1-hour exteriar room, a 1-hour
<br />interior room or a gas cabinet in accordance with Section
<br />5306.2.1, 5306.2.2 or 530623, respectively. Rooms or areas
<br />where medical gases are stored or used in quantities exceed-
<br />ing the �naxinium allowc�ble quantity per control area as set
<br />forth in Section 5003.1 shall be in accordance with the Inter-
<br />iaationc�l Buildii2g Code for high-hazard Group H occupan-
<br />cies.
<br />5306.2.1 One-hour exterior rooms. A 1-hour exterior
