Current through Register Vol. 24-14, July 15, 2024
(1)
				  Containers must be located to minimize the possibility of damage to the
				  container. Containers located in the rear of trucks and buses, when protected
				  by substantial bumpers meet this requirement. Fuel containers on
				  passenger-carrying vehicles must be installed as far from the engine as is
				  practical, and the passenger space and any space containing radio equipment
				  must be sealed from the container space to prevent direct seepage of gas to
				  these spaces. The container compartment must be vented to the outside. In case
				  the fuel container is mounted near the engine or the exhaust system, the
				  container must be shielded against direct heat radiation.
(2) Containers must be installed with as much
				  clearance as practical and at least the minimum road clearance of the vehicle
				  under maximum spring deflection. This minimum clearance must be to the bottom
				  of the container or to the lowest fitting on the container or housing,
				  whichever is lower.
(3) Permanent
				  and removable fuel containers must be securely mounted to prevent jarring
				  loose, slipping, or rotating, and the fastenings must be designed and
				  constructed to withstand static loading in any direction equal to twice the
				  weight of the tank and attachments when filled with fuel using a safety factor
				  of at least four based on the ultimate strength of the material to be used.
				  Field welding, when necessary, must be made only on saddle plates, lugs or
				  brackets, attached to the container by the manufacturer.
(4) Fuel containers on buses must be
				  permanently installed.
(5)
				  Containers from which only vapor is to be withdrawn must be installed and
				  equipped with suitable connections to minimize the accidental withdrawal of
				  liquid.

Current through Register Vol. 24-14, July 15, 2024
(1)
				  Spring-loaded internal safety-relief valves must be used on all motor fuel
				  containers.
(2) The discharge
				  outlet from safety-relief valves must be located on the outside of enclosed
				  spaces and as far as practical from possible sources of ignition, and vented
				  upward within 45 degrees of the vertical to prevent impingement of escaping gas
				  upon containers, or parts of vehicles, or on vehicles in adjacent lines of
				  traffic. A rain cap or other protector must be used to keep water and dirt from
				  collecting in the valve.
(3) When a
				  discharge line from the container safety-relief valve is used, the line must be
				  metallic, other than aluminum, and must be sized, located, and maintained so as
				  not to restrict the required flow of gas from the safety-relief valve. The
				  discharge line must be able to withstand the pressure resulting from the
				  discharge of vapor when the safety-relief valve is in the full open position.
				  Flexible metal hose or tubing must be used when necessary.
(4) Portable containers equipped for
				  volumetric filling may be filled in either the vertical or horizontal position
				  only when oriented to place the safety-relief valve in communication with the
				  vapor space.

				  vaporizer. It must be located at or near the lowest portion of the section
				  occupied by the water or other heating medium.
(3) Vaporizers must be securely fastened to
				  minimize the possibility of loosening.
(4) Each vaporizer must be permanently marked
				  at a visible point as follows:

Current through Register Vol. 24-14, July 15, 2024
(1) Approved automatic pressure reducing
				  equipment must be installed securely between the fuel supply container and
				  gas-air mixer to reduce the pressure of the fuel delivered to the gas-air
				  mixer.
(2) An approved automatic
				  shut-off valve must be provided in the fuel system at some point ahead of the
				  inlet of the gas-air mixer, designed to prevent flow of fuel to the mixer when
				  the ignition is off and the engine is not running. For industrial trucks and
				  engines operating in buildings other than those used exclusively to house
				  engines, the automatic shut-off valve must be designed to operate if the engine
				  stops. Atmospheric regulators (zero governors) are adequate as an automatic
				  shut-off valve only in cases of outdoor operation such as farm tractors,
				  construction equipment, irrigation pump engines, and other outdoor stationary
				  engine installations.
(3) The
				  source of air for combustion must be completely isolated from the passenger
				  compartment, ventilating system, or air-conditioning system.
