European foreword
This document (prEN 14841:2022) has been prepared by Technical Committee CEN/TC 286 “Liquefied
petroleum gas equipment and accessories”, the secretariat of which is held by NSAI.
This document is currently submitted to the CEN Enquiry.This document will supersede EN 14841:2013.
In comparison with the previous edition, the following technical modifications have been made:
— Removal of the Annex A on the Environmental checklist, addition of a reference to CEN/TS 16765;
— A new Annex A was added giving recommendations on the personal protection equipment;
— Updating of the Introduction;— Additionally to the discharge of LPG, also requirements for the filling of LPG were added;
— The standard was harmonized in both the filling and the discharge sections with EN 13776;
— A new clause on Integrate shut down systems was added.This document will be submitted for reference in
— the RID and/or
— the technical annexes of the ADR [4]
NOTE These regulations take precedence over any clause of this standard. It is emphasized that RID/ADR are
being revised regularly at intervals of two years which can lead to temporary non-compliances with the clauses of
this standard.---------------------- Page: 5 ----------------------

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 might be
beneficial to refer to the leaflet “measurement uncertainty leaflet” SP INFO 2000 27 [3].

4 General operation
Handling operations such as:
— accepting rail tankers upon arrival;
— filling and/or discharge of LPG; and
— preparation and returning rail tanker
shall be carried out under the supervision of a competent person (e.g. operator of the site) and shall be
in accordance with the site procedures.5 Procedures
5.1 General
Site procedures in written form including emergency procedures shall be available, understood and
followed by all persons involved in each operation. This shall be achieved by training and supervision.
The responsibilities of the persons involved shall be clearly defined.The procedures shall include a check of the rail tanker that is to be carried out before it is accepted. This

— an identification check of LPG quality and grade.
In case of transfer to/from another tanker, the procedures shall also include the check of that other
tanker.Where deficiencies are found they shall be recorded and reported to the appropriate body (e.g. rail tanker
loader) and the rail tanker operator. A rail tanker shall not be filled and/or discharged until any necessary
remedial work has been completed.Copies of checklists and deficiency reports shall be retained.
Personnel carrying out LPG transfer operations shall wear personal protection equipment according to
applicable regulations. Recommendations are given in Annex A. Filling and/or discharging shall be done
under the constant supervision of a competent person.The filling and discharge areas shall be inspected for fire hazards prior to beginning operations. Suitable
fire protection shall be readily available.NOTE Responsibilities for fire protection are subject to national regulations.
5.2 Filling
5.2.1 Preparation for filling
5.2.1.1 The rail tanker to be filled shall be moved to the filling area and positioned in accordance with
the site procedures.5.2.1.2 The filling operative shall ensure that any device provided to check the loaded quantity (e.g.
by weight) is operational.5.2.1.3 Parking brakes and railway wheel chock or other equivalent means shall be applied to
prevent unintended movement of any tanker involved during filling. The site, where the rail tank
