Full Description BS EN ISO 14122-2:2016 gives requirements for non-powered working platforms and walkways which are a part of a stationary machine, and to the non-powered adjustable parts e. NOTE 1 "Fixed" means of access are those mounted in such a manner for example, by screws, nuts, welding that they can only be removed by the use of tools. This part of ISO 14122 specifies minimum requirements that also apply when the same means of access is required as the part of the building or civil construction e. NOTE 2 Where no local regulation or standards exist, this part of ISO 14122 can be used for means of access which are outside the scope of the standard. It is intended that this part of ISO 14122 be used with ISO 14122-1 to give the requirements for walking platforms and walkways. The ISO 14122 series as a whole is applicable to both stationary and mobile machinery where fixed means of access are necessary. It is not applicable to powered means of access such as lifts, escalators, or other devices specially designed to lift persons between two levels. This part of ISO 14122 is not applicable to machinery manufactured before the date of its publication. Cross References:.

The width of the walkway, when designated as an escape way shall meet the requirements of appropriate regulations. If there are isolated obstacles on a wall or under a ceiling that restrict the required width or height, guarding shall be provided. Moreover, safety measures, e. Warning signs should also be considered. Guard-rails are also required at places where there is a risk of sinking or collapsing e.

Appropriate facilities shall be provided for handling heavy objects without rolling or placing them on working platforms.

If this requirement is not possible to fulfil for some special reasons, slipping and other hazards caused by the liquid shall be prevented or minimized in some other suitable way. Therefore, permeable floorings such as gratings or cold formed planks are an advantage. In cases where the risk assessment concludes that hazards caused by objects or other materials falling or passing through the flooring are more significant than the slipping, falling, etc.

EN ISO 14122-2:2001 4. Whilst waiting for the European standards on enhanced slip resistance, see informative annex A.

The safe strength design of the walkways and working platforms shall be verified either by calculation or by tests.

What is a permanent means of access? A permanent means of access is fixed to the machine or an adjacent structure in such a way that it cannot be removed without the use of tools.

As well as applying to rigidly attached means of access, the standard also applies to non-powered adjustable or movable parts such as sliding or folding ladders. Furthermore, the standard applies to parts of the building or civil construction if the main function of these is to provide access to the machine.

For the purposes of BS EN ISO 14122, permanent means of access are working platforms, walkways, stairs, stepladders, guard rails and fixed ladders. However, the scope of the standard specifically excludes powered means of access lifts, escalators or other devices designed to move persons between levels.

BS EN ISO 14122 Part 1: Choice of fixed means and general requirements of access Part 1 contains useful definitions, such as those for fixed ladder, stepladder, stair and ramp essentially the differences relate to the angle of pitch, and ladders have rungs whereas stepladders and stairs have steps.

When most people refer to stepladders they probably mean a short ladder with folding legs that enable it to be free-standing. Clause 4 of Part 1 lists the most significant hazards to consider when determining the type and location of the means of access.

BS EN ISO 14122-2:2016

An additional note draws attention to other possible hazards, and the reader is also reminded of ISO 12100 relating to risk assessments. Where there are hazards not covered by the standard, such as moving parts of machinery, extreme temperatures or hazards caused by the environment, the standard says that these should be considered and addressed by, for example, preventing unauthorised access.

In other words, when designing and specifying means of access, consideration should be given to preventing unauthorised access.

One issue that is not addressed particularly well in the standard is the question of under what circumstances a permanent means of access is required, though an ISO 12100 risk assessment will help.

Furthermore, three-point contact needs to be maintained except for very brief periods eg starting a screw , heavy objects should not be carried, leaning ladders should be secured and, if stepladders are used and side loads are imposed, then the stepladder should be secured. In general, if it is anticipated that regular access will be required for machine operation, cleaning or maintenance, then a permanent means of access should be given due consideration see also Clause 5 below.

Furthermore, a permanent means of access can prove to be very cost-effective compared with the cost of erecting scaffolding on multiple occasions. Clause 5 lists the general requirements for design and construction of means of access. Note that subclause 6.

References are made to other subclauses that help in determining which type of access should be selected, but the point to note is that there must be good reasons for using any means of access other than those listed higher up the hierarchy. Following on from the above, subclause 6. Annex A gives examples of changes that can be made to the machine or system to make better access possible. However, it is almost inevitable that Part 3 will also be required, because this covers the guard-rails that are usually necessary with platforms and walkways.

Subclause 4. Interestingly, a pragmatic approach is adopted, with several exceptions allowed under particular circumstances.

However, great care should be taken with ribbed ramps, bearing in mind that subclause 4. Nevertheless, it would be prudent to verify the safety requirements either by calculation or testing. Annex A relates to methods for determining slip resistance and starts by stating that no international standard currently exists.

Annex B lists the significant technical changes between ISO 14122-2:2016 and the previous edition, which will be helpful to readers who have been working on the earlier edition.

If guard-rails are being installed alongside platforms or walkways, Part 3 will have to be used in conjunction with Part 2 as well.

Another point to note from the definitions is that handrails must be rigid, which excludes the use of ropes, chains or cables. Clause 4 presents the General requirements for stairs, stepladders and guard-rails, including the loadings to be used in strength and deflection calculations when designing these structures.

Safety of machinery — Permanent means of access to machinery —

Clause 5, Specific requirements applicable to stairs, provides further information for designing stairs. Some leeway is provided for designers, as shown by this example from subclause 5.

Clause 6, Specific requirements applicable to step ladders, provides similar details to those in Clause 5. Subclause 7. However, the same subclause states that the minimum height of the guard-rail shall be 1100 mm, so it appears that the former may be a typographical error and the height of the handrail should be greater than or equal to 1100 mm.
