EN 12111:2002+A1:2009 (E) 5 Introduction This document is a type C-standard as stated in EN 1070. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indi-cated in the scope of this document.
Due to the wide range of geological and environmental conditions in which these types of machines are likely to be employed, it is not possible always to give precise technical requirements in this standard.
The particular conditions of use and places of use of the machinery (e.g. ground and local safety conditions, haz-ardous gas concentration (see 5.5.3)) are the subjects of negotiation between the manufacturers and the user/purchaser. NOTE “Manufacturer” should be understood within the European Union as intended in the Machinery Directive. When provisions of this type C standard are different from those which are stated in type A or B standards, the pro-visions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.

6 1 Scope 1.1
Description of the machine This European Standard specifies all significant hazards, hazardous situations and events relevant to road headers, continuous miners and impact rippers, when they are used as intended and under the conditions foreseen by the manufacturer (see clause 4). This standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. This European Standard is applicable to road headers, continuous miners and impact rippers used in tunnelling and underground mining. Certain associated matters are not included in the scope of this standard:  the supply of electricity up to the machine;  the provision of a cab or similar accommodation for an operator;  ancillary tools and equipment used for, at or on the machine;  equipment for use in potentially explosive atmospheres;  any method for monitoring gases in the atmosphere of the tunnel or other workplace;  the method of calculation of the design of any part described or the verification of this;  loading and transport equipment which is not an integral part of the machine;  electromagnetic compatibility;  pressure vessels. NOTE 1 Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmos-pheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC. NOTE 2
prEN 1710 “Equipment and components intended for use in potentially explosive atmospheres in mines” is currently under preparation in CEN/TC 305. 1.2 This standard deals with all significant hazards, hazardous situations and events relevant to road headers, continuous miners and impact rippers, when they are used as intended and under the conditions foreseen by the manufacturer (see clause 4). This standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. 1.3 This document is not applicable to machines which are manufactured before the date of publication of this document by CEN. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
