BS EN 13776:2013EN 13776:2013 (E) 4 Introduction This European Standard calls for the use of substances and procedures that may be injurious to health and/or the environmen
20、t 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. Protection of the environment is a key political issue in Europe and elsewhere around the world. Protection of the environment in this document is
21、 understood in a very broad sense. The phrase is used, for example, in relation to the total life-cycle aspects of a product on the environment, including expenditure of energy, and during all phases of its existence, from mining of raw materials, to fabrication, packaging, distribution, use, scrapp
22、ing, recycling of materials, etc. NOTE Annex B comprises an environmental checklist which highlights the clauses of this European Standard that address environmental aspects. Provisions have to be restricted to a general guidance. Limit values are specified in national laws. It is recommended that m
23、anufacturers develop an environmental management policy. For guidance see the EN ISO 14000 series 2, 3 and 4. It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. All pressures are gauge pre
24、ssures unless otherwise stated.

31、 be used. Personnel carrying out LPG transfer operations shall wear personal protection equipment according to applicable regulations. Filling and discharging shall be under the constant supervision of a competent person. 4.2 The filling and discharge areas shall be inspected for fire hazards prior
32、to beginning operations. Suitable fire protection shall be readily available. NOTE Responsibilities for fire protection are subject to national regulations 4.3 Written procedures and other appropriate information shall be made readily available, understood and followed by those undertaking filling a
33、nd discharging procedures. The training programme for driver certification shall be approved by the competent authority. Consideration shall be given to include specific instructions for the use of the road tankers LPG equipment and fixed LPG installation relevant to the operations in the training p
34、rogramme. 4.4 Written procedures shall be readily available, understood and followed. This shall be achieved by training and supervision. The responsibilities of all persons involved in the operation shall be clearly defined. For appropriate measures regarding training and written procedures and the
35、 corresponding responsibilities refer to national health and safety regulation. 5 Filling procedures 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 The filler shall ensure that any device provided to check
36、 the loaded quantity is 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. 5.1.4 The handbrake shall be applied and, where required, the wheel-sco
37、tch put in place. Anti-drive-away system interlock/installation barriers shall be engaged. 5.1.5 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 Annex A).
38、 NOTE In the ADR the terms “placarding” and “orange-coloured plate marking“ are used in place of “labelling”. Road tankers with pressure vessels which are not divided by partitions or surge plates into sections of not more than 7 500 litres capacity, shall be filled to not less than 80 % or not more
39、 than 20 % of their capacity. 5.1.6 Where fitted tanker loading control systems shall be connected. 5.2 Filling operations 5.2.1 The electrostatic potential of the road tanker and the fixed installation shall be equalised before the LPG hoses are connected. 5.2.2 All road tanker outlets and internal
40、 valves shall be checked to ensure that they are in the closed position. BS EN 13776:2013EN 13776:2013 (E) 7 5.2.3 The blanking cap shall be removed from the vapour return (where fitted and when used) and the liquid inlet connections. 5.2.4 The transfer couplings (hoses or loading arms) shall be con
41、nected without submitting them to any abnormal stresses. The road tanker, product terminal and vapour return valves, where applicable, shall be opened in the required sequence and manner in accordance with the written procedures. The connections between the transfer couplings and the road tanker sha
42、ll be checked for leakage. Further periodic leakage checks shall be carried out directly after the product transfer operation has begun. 5.3 Completion of filling 5.3.1 The road tanker, product terminal and vapour return valves, where applicable, shall be closed in the required sequence and manner i
43、n accordance with the written procedures ensuring that valves closest to the pressure vessel of the vehicle are closed first. 5.3.2 Any LPG between the transfer couplings shall be vented in a safe manner before fully disconnecting. 5.3.3 After disconnection of the filling line and any other connecti
44、ons to the road tanker (vapour return or tanker loading control) all road tanker valves shall be properly closed and the caps secured in place. 5.3.4 A final check shall be made to ensure that the road tanker is in a fit condition to be driven away. There shall be no sign of leakage. The connection
45、made to equalise the electrostatic potential shall be disconnected. 5.3.5 Anti-drive-away system interlock/installation barriers shall be disengaged. 5.3.6 The driver shall verify that the correct quantity and grade of LPG (as per dataplate of the pressure vessel, see Annex A) has been loaded and th
46、at the road tanker displays the appropriate hazard warning labels and the legal restrictions applicable are observed before leaving the site. 5.3.7 The driver shall verify completeness and correctness of the required documentation. 5.4 Precautions against overfilling 5.4.1 The gross vehicle mass (we
47、ight) shall not be exceeded when the mass of the road tankers fuel and the driver are taken into account. 5.4.2 Gauging devices shall be monitored continuously during the filling operation, to ensure that the road tanker is not overfilled. 5.4.3 If a road tanker is accidentally overfilled the excess
48、 LPG shall be removed in a controlled manner without delay, before departure of the road tanker. 5.4.4 When filling by mass, the tare of the vehicle shall be determined i.e. by weighing before every filling operation to ensure that the vehicle is not overfilled. 6 Discharging procedures 6.1 Preparat
