Introduction
This document calls for the use of substances and procedures that can be injurious to health if adequate
precautions are not taken. It refers only to technical suitability and does not absolve the user from legal
obligations relating to health and safety at any stage.
The frequencies of the different types of pressure vessel inspection are given by the relevant international
regulations concerning the transport of dangerous goods.
Protection of the environment is a key political issue in Europe and elsewhere. For CEN/TC 286 this is
covered in CEN/TS 16765 [1], and this Technical Specification should be read in conjunction with this
document. CEN/TS 16765 provides guidance on the environmental aspects to be considered regarding
equipment and accessories produced for the LPG industry and the following is addressed:
a) design;
b) manufacture;
c) packaging;
d) use and operation; and
e) disposal.
It is recommended that companies using this document develop an environmental management policy.
For guidance, see EN ISO 14001 [2].
It has been assumed in the drafting of this document that the execution of its provisions is entrusted to
appropriately qualified and experienced people.
All pressures are gauge pressures unless otherwise stated.
NOTE This document requires measurement of material properties, dimensions and pressures. All such
measurements are subject to a degree of uncertainty due to tolerances in measuring equipment, etc. It can be
beneficial to refer to the leaflet “Measurement uncertainty leaflet” SP INFO 2000 27 [4].

5.1 Preparation for filling
5.1.1 The vehicle shall be driven to the filling area and positioned in accordance with the site procedure.
5.1.2 Any device intended to or provided to check the loaded quantity shall be operational and in the
correct position.
5.1.3 All road tanker electrical equipment not required for the filling process shall be switched off. Any
other sources of ignition shall be removed/de-activated. All electrical equipment required for the filling
process shall be suitable for the hazardous zone according to ATEX.
NOTE Refer to Directive 2014/34/EU [7] and EN IEC 60079-10-1:2021 [3].
5.1.4 The handbrake shall be applied and, where required, the wheel chock put in place. Anti-drive-
away system interlock/installation barriers shall be engaged.
5.1.5 The electrostatic potential of the road tanker and the discharging pressure vessel shall then be
equalised before the LPG hoses or loading arms are connected.
5.1.6 All road tanker valves shall be checked to ensure that they are in the closed position.
5.1.7 Blanking caps or blind flanges shall be removed from the liquid and vapour connections (where
fitted and when used) to be used.
5.1.8 Ensure that the site is safe for filling LPG and adequate ullage capacity is available. Specific
requirements for this shall be part of the site procedures, if applicable.
5.1.9 Hoses and loading arms shall be checked for kinks, wear or obvious damage. Fill-couplings, seals
and necessary attachments shall be examined to ensure compatibility and that no dirt or any other
foreign matter is present before connection.
5.1.10 Connections shall be properly made before starting to fill. Hoses/loading arms shall not be fully
extended in making the connections. A check shall be made for any sign of leakage before filling
commences. Any leakage shall be rectified before proceeding.
5.1.11 Precautions shall be taken to ensure that the grade of LPG to be filled is correctly identified and
that the road tanker is suitable for the intended load and that it is correctly labelled (see ADR,
4.3.3.2.5 [5]).
