Introduction
This document calls for the use of substances and procedures that may be injurious to health and/or the
environment if adequate precautions are not taken. It refers only to technical suitability: it does not
absolve the user from their legal obligations at any stage.
It is recommended that manufacturers develop an environmental management policy. For guidance, see
the EN ISO 14000 series [1], [2] and [3].
Protection of the environment is a key political issue in Europe and elsewhere. For TC 286 this is covered
in CEN/TS 16765 [4] LPG equipment and accessories - Environmental considerations for CEN/TC 286
standards, and this Technical Specification should be read in conjunction with this standard. The
Technical Specification 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 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.
