The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 14122 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 14122-1 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee TC 199, Safety of machinery, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). Throughout the text of this standard, read “.this European Standard.“ to mean “.this International Standard.“. ISO 14122 consists of the following parts, under the general title Safety of machinery Permanent means of access to machinery: Part 1: Choice of fixed means of access between two levels Part 2: Working platforms and walkways Part 3: Stairs, stepladders and guard-rails Part 4: Fixed ladders Annex A of this part of ISO 14122 is for information only.

This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. -,-,- ISO 14122-1:2001(E) vi© ISO 2001 All rights reserved Introduction EN ISO 14122 consists of the following parts, under the general title “Safety of machinery - Permanent means of access to machinery“ : Part 1 :Choice of a fixed means of access between two levels Part 2 :Working platforms and walkways Part 3 :Stairs, stepladders and guard-rails Part 4 :Fixed ladders. This part of EN ISO 14122 is a type B standard as stated in EN 1070. This document is to be read in conjunction with clause 1.6.2 “Access to operating position and servicing points“ and 1.5.15 “Risk of slipping, tripping or falling“ of the essential safety requirements expressed in annex A of EN 292-2:1991/A1:1995. See also 6.2.4 “Provision for safe access to machinery“ of EN 292-2:1991. For the significant hazards covered by this part of EN ISO 14122, see clause 4. The provisions of this document may be supplemented or modified by a type C standard. NOTE 1For machines which are covered by the scope of a type C standard and which have been designed and built according to the provisions of that standard, the provisions of that type C standard take precedence over the provisions of this type B standard. “ NOTE 2The use of materials other than metals (wood composite materials, so-called “advanced“ materials, etc.) does not alter the application of thispart of EN ISO 14122.

It gives advice about the correct choice of access means when the necessary access to the machine is not possible directly from the ground level or from a floor. This part of EN ISO 14122 applies to all machinery (stationary and mobile) where fixed means of access are necessary. This part of EN ISO 14122 applies to means of access which are a part of a machine. This part of EN ISO 14122 may also apply to means of access to that part of the building (e.g. working platforms, walkways, ladders) where the machine is installed, providing the main function of that part of the building is to provide a means of access to the machine. NOTEThis part of EN ISO 14122 may be used also for means of access which are outside the scope of this part of EN ISO 14122. In those cases the possible relevant national or other regulations should be taken into account. This part of EN ISO 14122 applies also to access means specific to the machine which are not permanently fixed to the machine and which may be removed or moved to the side for some operations of the machine (e.g. changing tools in a large press). This part of EN ISO 14122 does not apply to lifts, to moveable elevating platforms or other devices specially designed to lift persons between two levels 2Normative 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.

Other hazards generated by the machinery, e.g. caused by the functioning of the machinery (moving parts of the machine, movement of the machine itself (mobile machines), radiation, hot surface, noise, steam, hot liquids) or caused by its environment (harmful airborne substances) are not covered by this part of EN ISO 14122 but the designer of the machine should consider them, e.g. by preventing the access. NOTEEN 1050 gives principles for risk assessment. This part of EN ISO 14122 is primarily aimed at the prevention of persons falling and of excessive physical efforts. 5Requirements for the selection of the fixed means of access 5.1General There shall be a safe and convenient means of access to all the zones and points of the machine where the need for access can be foreseen during the phases of the “life“ of the machinery (see 3.11 of EN 292-1:1991). -,-,- ISO 14122-1:2001(E) 4© ISO 2001 All rights reserved 5.2Preferred means of access The preferred means of access to the machinery shall be in the following order : a)access directly from the ground level or from a floor, (for more details see 5.3.1.1 and EN ISO 14122-2) ; b)lifts, ramps or stairs, (for more details see 5.4) ; c)stepladders or ladders, (for more details see 5.5). 5.3Selection of the means of access 5.3.1Basic solutions 5.3.1.1Whenever possible, access to control devices and other parts of the machine is preferred from either a ground level or a floor. This is particularly important where frequent access is required. 5.3.1.2If level access according to 5.3.1.1 is not possible or practicable, a lift or suitable ramp with an angle of pitch less than 10 ° (see 5.4.b) or stairs with an angle of pitch from a minimum of 30 ° to maximum of 38 ° (see 5.4.c) shall normally be selected as a safe and suitable basic solution for the necessary access. 5.3.2Conditions for the selection of stepladder or ladder 5.3.2.1In the design of access to machinery, stepladders and ladders shall be avoided as far as practicable due to the higher risk of falling and because of the higher physical efforts when using these access means. 5.3.2.2If access means according to 5.3.1 are not possible, selection of a stepladder or ladder may be considered. The final decision shall be made on the basis of the risk assessment, including ergonomic aspects. If the level of risk (see EN 1050) is considered to be too high, the basic construction of the means of access to the machine shall be changed to allow accessways with a reduced risk to be used (see 5.3.1 and annex A). 5.3.2.3The following list presents some examples of the cases when a stepladder or ladder may be selected. These are only examples - the final selection shall always be done case by case on the basis of risk assessment. In most cases more than one of the conditions in the following list shall be fulfilled to make the selection of a stepladder or ladder possible. a)Short vertical distance. b)The means of access is foreseen to be used infrequently. NOTEWhen estimating the frequency of the use, the whole life of the machinery is considered. If the means of access is to be used frequently, e.g. during the assembly or installation of the machine or during periodical major maintenance tasks, a stepladder or ladder is not an adequate solution. c)The user will not be carrying any large tools or any other equipment when using the means of access.
