Section 1276.5 - Tank vehicle and refueling service vehicle equipment

(a) Tires. All tank vehicles shall be equipped with pneumatic tires.

(b) Trailer mounting. Semi-trailers shall be mounted by means of a fifth-wheel connection, the lower half of which shall be securely fastened to the tractor frame, and the upper half securely fastened to the semi-trailer. A locking mechanism shall be provided so the upper and lower halves may not be separated except by manual release and a safety bolt or wire seizing shall be applied to retain the manual release.

(c) Wiring and lighting. Ignition wiring, both primary and secondary, shall be fully insulated, adequately supported and protected against chaffing. Terminals shall be firmly attached and spark plug attachments shall be further protected by and insulating tight fitting shroud of the molded boot type. Tank or refueling service vehicles shall not be equipped with any artificial lighting other than electric lighting. Lighting circuits shall have over current protection by means of fuses or circuit breakers. Over current protection devices shall not be rated more than 115 percent of the allowable ampacity of the conductor. Where circuits feed motor loads, the over current protection devices shall be capable of carrying the starting current of the motor, but shall not exceed 250 percent of the motor full load current. Wiring of light circuits other than standard factory wiring serving the vehicle engine and front lights shall have sufficient carrying capacity to prevent dangerous heating and sufficient mechanical strength being flame retardant, moisture-heat and oil-resistant type MTW (Underwriters' Laboratories approved) and construed for service conditions, and shall be secured, insulated and protected against physical damage by encasing in metallic tubing with all connections made at standard metal outlet boxes or at standard fixtures.

(d) Fuel system for propulsion of tank vehicles.

(1) Fuel tanks. The fuel tank used in the system for propulsion of the vehicle shall have a maximum capacity of 45 gallons of fuel, and shall be installed within the frame of the vehicle or otherwise protected against mechanical injury. The tank shall be arranged to vent during filling operations and permit draining without removal from the mountings. Tanks installed within the cab of a vehicle shall be filled and vented from outside of the cab.

(2) Feed system. The fuel for propulsion of the vehicle shall be delivered to the engine by a mechanical or electrical pump. No readily combustible material shall be used in the engine exhaust system. The fuel feed lines shall be impervious to corrosive action of the fuel used, and shall be so arranged that the suction shall be taken from the top of the tank; such feed lines shall have adequate strength for their purpose and shall be well secured against chafing and vibration. The carburetor shall be equipped with a standard air cleaner-backflash arrestor; direct drainage of overflow gasoline shall be provided for. No glass bowls, glass gauges or readily breakable parts are to be used in any part of the fuel feed system, except that a glass bowl may be used on a fuel pump provided it is so constructed and installed that if it breaks, the engine will automatically stop.

(3) When refueling vehicles are without motive power and are equipped with draw handles, the draw handles shall be hinged and held in the vertical position when not in use by a suitable holding device. The maximum height of the draw handle in the vertical position shall not exceed six feet from the ground level to the highest point.

(e) Engine and exhaust system. The vehicle propulsion and product pumping engine shall be installed under or forward of the cab portion of single units, on the tractor of semi-trailer units or otherwise located in a separate compartment independent of the cargo tank and not subject to flooding or leakage of product from the cargo tank, any pumps or product handling components. The engine compartment must be independent of the cargo tank, fully ventilated and accessible for fire fighting. Engine exhaust systems, including the muffler and the exhaust line shall be separated by at least three inches from the engine fuel system, from all combustible material, and shall not be exposed to accumulations or leakage of grease, oil, gasoline or the product carried. An approved muffler shall be installed and no muffler cutout shall be used. The muffler tail pipe shall be turned down and terminate not less than three feet horizontally from the cargo tank, and from the fuel handling equipment.

(f) Brakes. Every tank vehicle shall be equipped with manually controlled holding or parking brakes. All such brakes shall be controlled by the driver of the vehicle and set during fuel transfer or parking. Every tank semi-trailer shall be equipped with brakes of such a character as to be automatically applied upon break-away from the towing vehicle and shall be designed to stop and hold such vehicles for 15 minutes. In any tank semi-trailer the brakes shall be of such design that the brakes on the trailer may be applied almost simultaneously or prior to the brakes on the tractor. Vehicles equipped with air brake interlocks between brakes and power take-off units shall be fitted with a properly marked emergency brake release located at the front bumper of the vehicle to permit brake release and towing the vehicle in event of an emergency. Vehicles equipped with air brakes shall be fitted with a low pressure alarm buzzer audible under all conditions of operation, located in the driver's cab. Vehicles arranged for bottom loading shall have the brake's system interlocked with the bottom loading valve housing cover so the vehicle brakes are set and the vehicle could not be moved until the bottom loading hose lines are disconnected and the housing cover is latched close.

(g) Limitations. Tank vehicles operated on air terminal highways shall conform with all applicable portions of the State motor vehicle rules and regulations, provided that tank vehicles restricted to operation on terminal building aprons, hangar aprons, cargo building operating aprons, or special service roads not authorized for general public use, shall not exceed 102 inches maximum over-all width, and 35 feet maximum over-all length for a single unit or 50 feet maximum over-all length for a semi-trailer unit without special written permission of the airport operator.
