Some leeway is provided for designers, as shown by this example from subclause 5. Note that subclause 6. As with guards, when considering means of access the first approach should be to design-out the risks. Annex A ido, Requirements for the design of anti-climb devices, is normative and should, therefore, be complied with often an Annex to a standard is informative only.

Clause 6Specific requirements applicable to step laddersprovides similar details to those in Clause 5. For testing stepladders, the reader is referred to ENLadders. An additional note draws attention to other possible hazards, and the reader is also reminded of ISO relating to risk assessments.

As well as providing requirements for guard-rails on platforms, stairs and stepladders, Clause 7 also gives details for toe plates, self-closing gates and mezzanine gates. Safety-related parts of control systems General principles for design. In other words, when designing and specifying means of access, consideration should be given to preventing unauthorised access. Annex B informative illustrates the main dimensions of a fixed ladder equipped with a safety cage.

A final point to note is that ISO Part 5 is in preparation, which will deal with permanent means of access on mobile machinery. However, see Clause 6 below.

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. Annex A gives examples of changes that can be made to the machine or system to make better access possible.

If guard-rails are being installed alongside platforms or walkways, Part 141222-3 will have to be used in conjunction with Part 2 as well. Clause 5Specific requirements of ladder systemsprovides extensive information relating to ladder design, including the profiles and dimensions of rungs round rungs are not permitted. For a new machine that is being CE marked to the Machinery Directiveworking to the standard gives a presumption of conformity to the relevant EHSRs; without the standard, it is necessary to demonstrate that the EHSRs have been fulfilled by some other means.
