NOTE 1 Attachments mounted on the load carrier or on fork arms which are removable by the user are not considered to be a part of the truck.
This European Standard specifies supplementary technical requirements for the prevention of the ignition of an explosive atmosphere of flammable gases, vapours, mists or dusts by industrial trucks of equipment group II and equipment category 2G, 3G, 2D or 3D.
NOTE 2 The relationship between an equipment category (hereafter referred to as category) and the corresponding zone (area classification) is shown in informative Annex B.
This European Standard does not include:
- trucks of equipment group I;

Varnost vozil za talni transport - Obratovanje v potencialno eksplozivnih atmosferah - Uporaba v območju vnetljivega plina, pare, megle in prahu
Ta evropski standard velja za industrijska vozila z lastnim pogonom ter ročno in napol ročno gnana vozila (v nadaljevanju pogosto imenovana »vozila«) za uporabo v potencialno eksplozivnih atmosferah, vključno z njihovimi napravami za delo z bremenom in odstranljivimi priključki.
Vilice, nakladalne platforme ali integrirani priključki se obravnavajo kot deli vozila. Priključki, nameščeni na nosilec bremena ali na vilice, ki jih lahko odstrani uporabnik, se ne obravnavajo kot del vozila
Ta evropski standard obravnava le preprečevanje vžiga eksplozivne atmosfere s strani industrijskih vozil in opisuje dodatne zahteve za vozila skupine opreme II in kategorije opreme 2G, 3G, 2D in 3D.
Razmerje med kategorijami opreme in ustreznimi območji je prikazano v dodatku B.
Ta standard ne pokriva vozil za kategorijo 1 in vozil, namenjenih za uporabo v eksplozivnih atmosferah s hibridnimi mešanicami.
Vsa vozila, namenjena za uporabo v potencialno eksplozivnih atmosferah v obsegu tega evropskega standarda, morajo ustrezati zahtevam, podanim v tem evropskem standardu. Kjer lahko pride do dodatnih nevarnosti, bo izvedena ocena nevarnosti vžiga po standardu EN 13463-1:2009, pri čemer bodo upoštevane te posebne okoliščine in dodatne zahteve v standardu EN 13463-1:2009 ter po potrebi spremenjene v določenih delih standarda EN 13463 za druge vrste zaščite.
Ta evropski standard pokriva tehnične zahteve, potrebne za izogibanje ali zmanjšanje večjih nevarnosti, opredeljenih v dodatku A, do katerih lahko pride med običajnim delovanjem, vzdrževanjem ali predvidljivo nepravilno uporabo (skladno s podatki, ki jih zagotovi proizvajalec) industrijskih vozil.
Ta evropski standard ne velja za vozila, namenjena za uporabo v nevarnih atmosferah z ogljikovim disulfidom (CS2), ogljikovim monoksidom (CO) in/ali etilenoksidom (C2H4O) zaradi posebnih lastnosti teh plinov.
Vozila z oznako IIB + H2 in/ali C2H2 (vodik in/ali acetilen) so primerna tudi za atmosfero IIA ali IIB.
Ta evropski standard velja za atmosfere z razponom temperature v prostoru med -20 in +40 °C, tj. vozila, izdelana v skladu s tem evropskim standardom, bodo ustrezala poljubnim servisnim pogojem znotraj tega razpona, razen če ni določeno drugače.
OPOMBA Razpon temperature prostora (od -20 do +40 °C) je skladen s standardom EN 3691-1.

Introduction
This standard is a type-C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are
covered, are indicated in the scope of this standard.
When provisions of this type C standard are different from those which are stated in type A or B standards,
the provisions of this type C standard take precedence over the provisions of the other standards for
machines that have been designed and built in accordance with the provisions of this type C standard.
This standard (EN 1755:2015) covers safety requirements and their verification for industrial trucks as
defined in ISO 5053-1 that are not covered exhaustively by:
— EN 1459;
— EN 1526;
— EN 1757-3;
— EN ISO 3691-1;
— EN ISO 3691-5;
— EN ISO 3691-6;
NOTE The above-mentioned standards are listed in the Bibliography or in Clause 2.
Assessment of hazards
The industrial truck needs to be designed in such a way that it is fit for its purpose or function and can be
adjusted and maintained without putting persons at risk when used under the conditions foreseen (e.g.
explosive atmospheres) by the manufacturer.
In order to properly design an industrial truck and to cover all specific safety requirements, the
manufacturer will have to identify the hazards that apply to the industrial truck and carry out a risk
assessment. The manufacturer will then need to design and construct the industrial truck taking this
assessment into account.
The aim of this procedure is to eliminate the risk of accidents throughout the foreseeable lifetime of the
machinery, including the phases of assembling and dismantling where risks of accidents could also arise
from foreseeable abnormal situations.
In selecting the most appropriate methods, the manufacturer will need to apply the following principles, in
the order given here:
— eliminate or reduce risks as far as possible by design (inherently safe machinery design and
construction);
— take the necessary protective measures in relation to risks that cannot be eliminated by design;
— inform users of any shortcoming of the protective measures adopted;
— indicate whether any particular training is required;
— specify any need to provide personal protection equipment;
— refer to the appropriate user's document for proper operating instructions.
Industrial trucks need to be designed to prevent foreseeable misuse wherever possible, if such would
engender risk. In other cases, the instructions will need to draw the user's attention to ways shown by
experience in which the machinery ought not to be used.
This standard (EN 1755:2015) does not repeat all the technical rules which are state-of-the art and which
are applicable to the material used to construct the industrial truck. Reference will also need to be made to
EN ISO 12100.
