Dangerous Goods by Road
Electrical equipment
The electrical installation shall meet the relevant requirements of 9.2.2.1, 9.2.2.2 9.2.2.3, 9.2.2.4,
9.2.2.5, 9.2.2.6, 9.2.2.7, 9.2.2.8 and 9.2.2.9.2.
The electrical installation in the load compartment shall be dust-protected at least IP 54 according to
IEC 60529 or equivalent. In the case of carriage of items and articles of compatibility group J,
protection to at least IP 65 according to IEC 60529 or equivalent shall be provided.
No wiring shall be positioned inside the load compartment. Electrical equipment accessible from the
inside of the load compartment shall be sufficiently protected from mechanical impact from the inside.
ADDITIONAL REQUIREMENTS CONCERNING THE CONSTRUCTION OF THE BODIES OF COMPLETE OR COMPLETED VEHICLES INTENDED FOR THE CARRIAGE OF DANGEROUS GOODS IN PACKAGES (OTHER THAN EX/II AND EX/III VEHICLES)
Combustion heaters shall meet the following requirements:
(a) The switch may be installed outside the driver's cab;
(b) The device may be switched off from outside the load compartment; and
(c) It is not necessary to prove that the heat exchanger is resistant to the reduced afterrunning
cycle.
If the vehicle is intended for the carriage of dangerous goods for which a label conforming to models
Nos. 1, 1.4, 1.5, 1.6, 3, 4.1, 4.3, 5.1 or 5.2 is prescribed, no fuel tanks, power sources, combustion air
or heating air intakes as well as exhaust tube outlets required for the operation of the combustion
heater shall be installed in the load compartment. It shall be ensured that the heating air outlet cannot
be blocked by cargo. The temperature to which packages are heated shall not exceed 50º C. Heating
devices installed inside the load compartments shall be designed so as to prevent the ignition of an
explosive atmosphere under operating conditions.
Additional requirements concerning the construction of the bodies of vehicles intended for the
carriage of given dangerous goods or specific packagings may be included in Part 7, Chapter 7.2 in
accordance with the indications in Column (16) of Table A of Chapter 3.2, for a given substance.
ADDITIONAL REQUIREMENTS CONCERNING THE CONSTRUCTION OF THE BODIES OF COMPLETE OR COMPLETED VEHICLES INTENDED FOR THE CARRIAGE OF DANGEROUS SOLIDS IN BULK
Combustion heaters shall meet the following requirements:
(a) The switch may be installed outside the driver's cab;
(b) The device may be switched off from outside the load compartment; and
(c) It is not necessary to prove that the heat exchanger is resistant to the reduced afterrunning
cycle.
If the vehicle is intended for the carriage of dangerous goods for which a label conforming to models
Nos. 4.1, 4.3 or 5.1 is prescribed, no fuel tanks, power sources, combustion air or heating air intakes
as well as exhaust tube outlets required for the operation of the combustion heater shall be installed in
the load compartment. It shall be ensured that the heating air outlet cannot be blocked by cargo. The
temperature to which the load is heated shall not exceed 50 ºC. Heating devices installed inside the
load compartments shall be designed so as to prevent the ignition of an explosive atmosphere under
operating conditions.
The bodies of vehicles intended for the carriage of dangerous solids in bulk shall meet the
requirements of Chapter 6.11 and 7.3, as appropriate, including those of 7.3.2 or 7.3.3 which may be
applicable in accordance with the indications in columns (10) or (17) respectively of Table A of
Chapter 3.2 for a given substance.
ADDITIONAL REQUIREMENTS CONCERNING COMPLETE OR COMPLETED VEHICLES INTENDED FOR THE CARRIAGE OF TEMPERATURE CONTROLLED SUBSTANCES
Insulated, refrigerated and mechanically-refrigerated vehicles intended for the carriage of temperature
controlled substances shall conform to the following conditions:
(a) the vehicle shall be such and so equipped as regards its insulation and means of refrigeration,
that the control temperature prescribed in 2.2.41.1.17 and 2.2.52.1.16 and in 2.2.41.4 and
2.2.52.4 for the substance to be carried is not exceeded. The overall heat transfer coefficient
shall be not more than 0.4 W/m2K;
(b) the vehicle shall be so equipped that vapours from the substances or the coolant carried cannot
penetrate into the driver's cab;
(c) a suitable device shall be provided enabling the temperature prevailing in the loading space to
be determined at any time from the cab;
(d) the loading space shall be provided with vents or ventilating valves if there is any risk of a
dangerous excess pressure arising therein. Care shall be taken where necessary to ensure that
refrigeration is not impaired by the vents or ventilating valves;
(e) the refrigerant shall not be flammable; and
(f) the refrigerating appliance of a mechanically refrigerated vehicle shall be capable of operating
independently of the engine used to propel the vehicle.
Suitable methods (see V8(3)) to prevent the control temperature from being exceeded are listed in
Chapter 7.2 (R1 to R5). Depending on the method used, additional provisions concerning the
construction of vehicle bodies may be included in Chapter 7.2.
