The provisions laid down in ADR do not apply to the carriage of:

(a)    Gases contained in the fuel tanks or cylinders of a vehicle performing a transport operation and destined for its propulsion or for the operation of any of its equipment used or intended for use during carriage (e.g. refrigerating equipment).

The gases may be carried in fixed fuel tanks or cylinders, directly connected to the vehicle’s engine and/or auxiliary equipment or transportable pressure receptacles, which comply with   the pertinent legal provisions.

The total capacity of the fuel tanks or cylinders for a transport unit, including those allowed in accordance with 1.1.3.3 (a), shall not exceed the amount of energy (MJ) or mass (kg) corresponding to 54 000 MJ energy-equivalent.

NOTE 1:       The value of 54 000 MJ energy-equivalent corresponds to the fuel limit of 1.1.3.3
(a)    (1500 litres). For the energy content of fuels see the following Table:

The total capacity shall not exceed:
-    1 080 kg for LNG and CNG;
-    2 250 litres for LPG;

NOTE 2:       A container fitted with equipment for use during carriage, secured on a vehicle,  is considered as an integral part of the vehicle and benefits from the same exemptions as regards the fuel necessary to operate the equipment.

(b)    (Deleted)

(c)    Gases of Groups A and O (according to 2.2.2.1), if the pressure of the gas in the receptacle or tank at a temperature of 20 °C does not exceed 200 kPa (2 bar) and if the gas is not a liquefied or a refrigerated liquefied gas. This includes every kind of receptacle or tank, e.g. also parts of machinery and apparatus;

NOTE:    This exemption does not apply to lamps. For lamps see 1.1.3.10.

(d)    Gases contained in the equipment used for the operation of the vehicle (e.g. fire extinguishers), including in spare parts (e.g. inflated pneumatic tyres); this exemption also applies to inflated pneumatic tyres carried as a load;

(e)    Gases contained in the special equipment of vehicles and necessary for the operation of this special equipment during transport (cooling systems, fish-tanks, heaters, etc.) as well as spare receptacles for such equipment or uncleaned empty exchange receptacles, transported in the same transport unit;

(f)    Gases contained in foodstuffs (except UN 1950), including carbonated beverages; and

(g)    Gases contained in balls intended for use in sports.

(h)    (Deleted)
 

Certain special provisions of Chapter 3.3 exempt partially or totally the carriage of specific dangerous goods from the requirements of ADR. The exemption applies when the special provision is referred to in Column (6) of Table A of Chapter 3.2 against the dangerous goods entry concerned.

Certain dangerous goods may be subject to exemptions provided that the conditions of Chapter 3.4 are met.

Certain dangerous goods may be subject to exemptions provided that the conditions of Chapter 3.5 are met.

1.1.3.6.1    For the purposes of this sub-section, dangerous goods are assigned to transport categories 0, 1, 2, 3,   or 4, as indicated in Column (15) of Table A of Chapter 3.2. Empty uncleaned packagings having contained substances assigned to transport category "0" are also assigned to transport category "0". Empty uncleaned packagings having contained substances assigned to a transport category other than "0" are assigned to transport category "4".

Where the quantity of dangerous goods carried on a transport unit does not exceed  the  values indicated in column (3) of the table in 1.1.3.6.3 for a given transport category (when the dangerous goods carried in the transport unit belong to the same category) or the value calculated in accordance with 1.1.3.6.4 (when the dangerous goods carried in the transport unit belong to different transport categories), they may be carried in packages in one transport unit without application of the following provisions:

-    Chapter 1.10 except for Class 1 explosives of UN Nos. 0029, 0030, 0059, 0065, 0073, 0104,
0237, 0255, 0267, 0288, 0289, 0290, 0360, 0361, 0364, 0365, 0366, 0439, 0440, 0441, 0455,
0456 and 0500 and except for Class 7 excepted packages of UN Nos. 2910 and 2911 if the activity level exceeds the A2 value;
-    Chapter 5.3;
-    Section 5.4.3;
-    Chapter 7.2, except for V5 and V8 of 7.2.4;
-    CV1 of 7.5.11;
-    Part 8 except for    8.1.2.1 (a),
8.1.4.2 to 8.1.4.5,
8.2.3,

S1(3) and (6), S2(1),
S4; S5,
S14 to S21 and S24 of Chapter 8.5;
-    Part 9.
 

In the above table, "maximum total quantity per transport unit" means:

• For articles, total mass in kilograms of the articles without their packagings (for articles of Class 1, net mass in kilograms of the explosive substance; for dangerous goods in machinery and equipment specified in this Annex, the total quantity of dangerous goods contained therein in kilograms or litres as appropriate);

• For solids, liquefied gases, refrigerated liquefied gases and dissolved gases, net mass in kilograms;

• For liquids, the total quantity of dangerous goods contained in litres;

• For compressed gases, adsorbed gases and chemicals under pressure, the water capacity of the receptacle in litres.

Where dangerous goods of different transport categories are carried in the same transport unit, the  sum of:

-    The quantity of substances and articles of transport category 1 multiplied by "50";

-    The quantity of substances and articles of transport category 1 referred to in Note a to the table in 1.1.3.6.3 multiplied by "20";

-    The quantity of substances and articles of transport category 2 multiplied by "3"; and

-    The quantity of substances and articles of transport category 3; shall not exceed a calculated value of "1 000".
 

 For the purposes of this sub-section, dangerous goods exempted in accordance with 1.1.3.1 (a), (b)  and (d) to (f), 1.1.3.2 to 1.1.3.5, 1.1.3.7, 1.1.3.9 and 1.1.3.10 shall not be taken into account.
