20、andard does not purport to address all of the health and safety risks, if any, associated with its use. It is the responsibility of the user to establish appropriate health and safety practices and to ensure compliance with any national legislative and regulatory obligations. Users should perform th
21、eir own full risk assessment to address all of the health and safety risks, as required by national legislation. Training and competency requirements for personnel involved in the activities are not included in the scope of this standard but are planned to be addressed in a second part to this Europ
22、ean Standard. This European Standard specifies the requirements for working areas and the procedures for the installation of LPG systems on vehicles and for the repairing and maintenance of vehicles equipped with LPG systems. This European Standard should be used for aspects not covered by the manua
23、ls provided by the manufacturers of LPG vehicles and/or retrofit systems. Protection of the environment is a key political issue in Europe and elsewhere, for CEN/TC 286 this is covered in CEN/TS 16765 2 LPG equipment and accessories - Environmental considerations for CEN/TC 286 standards, and this T
24、echnical Specification should be read in conjunction with this standard. It is recommended that users develop an environmental management policy. For guidance see EN ISO 140213, EN ISO 14024 4 and EN ISO 14025 5. It has been assumed in the drafting of this European Standard that execution of its pro
25、visions is entrusted to appropriately qualified and experienced people. DIN EN 16652-1:2016-09EN 16652-1:2016 (E) 5 1 Scope This European Standard sets out the requirements for automotive LPG working areas and procedures, aimed at reducing the risk of fire and explosion of LPG when the following typ
26、es of work or activity are carried out: a) equipping vehicles with an LPG system to use LPG for propulsion purposes; b) maintenance, servicing and repairs to the LPG system; c) any other LPG vehicle maintenance, servicing or repairs not involving the LPG system. The operations described in items a)
27、and b) above are undertaken in dedicated LPG working areas, whereas item c) is undertaken in general service working areas. This Standard does not address how to equip a vehicle with an LPG retrofit system or how to repair or maintain an LPG vehicle. NOTE Such provisions are normally provided in the
28、 instruction manuals issued by the relevant manufacturers. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 liquefied petroleum gas LPG low pressure liquefied gas composed of one or more light hydrocarbon

39、applies to automotive working areas and servicing workshops which may be required to do work on any vehicle equipped with an LPG system but not on the LPG system itself (e.g. service station and lubrication bays, premises specializing in engine tuning, suspension, tyres or brakes and body repairs).
40、The presence of a vehicle equipped with a normally operating LPG system within the workshop shall not require any special extension of the normal ventilation, working space, and access to open space outside. 4.2 Dedicated LPG working areas 4.2.1 General 4.2.1.1 The requirements of this subclause app
41、ly to working areas where the equipping of vehicles with LPG systems, or the repairing and the maintenance of LPG systems are carried out. The atmosphere within the working area shall be maintained within occupational exposure limits during and after the operations are completed. 4.2.1.2 Subclauses
42、4.2.1.3 to 4.2.1.8 apply when: the components of the LPG system involved in any of the following operations contain gas at a pressure above atmospheric pressure; or the components of the LPG system involved in any of the following operations contain gas at a pressure less than or equal to atmospheri
43、c pressure and are not isolated from other parts of the system; or an increased hazard, as defined in 5.1.1, exists. 4.2.1.3 Where the equipping of vehicles to operate on LPG, or the repairing and the maintenance of LPG system are carried out, a working area shall be identified through a risk assess
44、ment. The risk assessment will include hazardous zone classification in accordance with ATEX requirements and any necessary ventilation requirements. DIN EN 16652-1:2016-09EN 16652-1:2016 (E) 8 NOTE For ATEX requirements see the relevant EU Directives (e.g. Directive 1999/92/EC 7 and 2014/34/EU 9) a
45、nd their transposition in national legislation. 4.2.1.4 If the working area does not encompass the entire workshop, it is advisable to clearly mark the designated working area(s) on the workshop floor. 4.2.1.5 In the working area, appropriate signage addressing the risks shall be displayed in accord
46、ance with national rules. 4.2.1.6 The floor level of the working area shall not constitute a depression in relation to the surrounding ground contours and levels unless appropriate extraction arrangements and gas detection systems are in place. 4.2.1.7 The working area shall not include or provide a
47、ccess to lower areas such as depressions, sumps, basements, unventilated pits, descending stairs, ramps or openings into drainage systems unless effectively sealed to prevent the ingress of LPG liquid or vapour. 4.2.1.8 The working area shall not be above any work space other than a properly ventila
