ROAD TRAFFIC (CONSTRUCTION AND MAINTENANCE OF VEHICLES) REGULATIONS - REGULATION 60

Fuel tanks, carburettors, etc. on buses and light buses

(1) No fuel tank shall, in any single-decked bus, half-decked bus or lower
deck of a double-decked bus, be placed under any part of any gangway or under
any part of any passage leading to an emergency exit (not being a
secondary emergency exit) if that part of the gangway or passage is within 600
millimetres of any entrance or exit.

(2) No fuel tank shall, in any light bus, be placed immediately under any
entrance or exit or within 300 millimetres of any entrance or exit and no
filling point for a fuel tank shall be situated at the rear of the vehicle.

(3) No part of any fuel tank or apparatus for the supply of fuel shall, in any
bus or light bus, be placed in the compartments or other spaces provided for
the accommodation of the driver or passengers.

(4) All fuel tanks and all apparatus supplying fuel to the engine shall, in
every bus and light bus, be so placed or shielded that no fuel overflowing or
leaking therefrom can fall or accumulate upon any woodwork forming part of the
vehicle or upon any other part of the vehicle or fitting thereto such that it
might readily be ignited or can fall into any receptacle where it might
accumulate.

(5) The filling points for all fuel tanks shall, in every bus and light bus,
be accessible only from the outside of the vehicle and filler caps shall be so
designed and constructed that they cannot be dislodged by accidental operation
and any vent hole shall be protected from danger of penetration by fire and
shall be so designed as to prevent fuel from being splashed over.

(6) A device shall be provided in every bus and light bus by means of which
the supply of fuel to any carburettor or, in the case of a fuel injection
pump, to the injection nozzles, can be readily cut off and the following
requirements shall be complied with in respect thereof-

   (a)  the means of operation shall at all times be readily accessible from
        outside the vehicle and, except in the case of a vehicle fitted with
        an engine having a fuel injection system, shall be readily visible
        from the outside of the vehicle; and

   (b)  in a case where the device is so visible, the "off" (停止操作)
        position of the means of operation thereof shall be clearly marked
        also on the outside of the vehicle, and in a case where the said
        device is not so visible, its position shall be clearly marked on the
        outside of the vehicle and the means of operation shall also be
        clearly indicated.
