Clause 5Specific requirements of ladder systemsprovides extensive information relating to ladder design, including the profiles and dimensions of rungs round rungs are not permitted. Annex B iiso illustrates the main dimensions of a fixed ladder equipped with a safety cage.
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.

If an anti-climb device is fitted to a ladder, a written warning or audible signal is not adequate for access control. Working platforms and walkways Status: Safety-related parts of control systems General principles for design. Note that subclause 6. The four parts are all Isk standards, meaning 141122-2 deal with specific aspects of machinery safety and can be applied to a wide range of categories of machinery.
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. 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.
An additional note draws attention to other possible hazards, and the reader is also reminded of ISO relating to risk assessments.
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.

Readers who are concerned about what changes might occur in relation to standards once the UK leaves the European Union can rest assured that it is unlikely that there will be any change here because BS EN ISO is equivalent to the international standard and it iwo all but inconceivable that the UK would cease to use this.

It will be used by: Means of access, as with guarding, help to control access to machine-related hazards under different circumstances — such as operation, cleaning and maintenance — and should not themselves introduce significant new risks. 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.

As with guards, when considering means of access the first approach should be to design-out the risks. Machine manufacturers small, medium and large enterprises Health and safety bodies regulators, accident prevention organizations, market surveillance, etc. Another point to note from the definitions is that handrails must be rigid, which excludes the use of ropes, chains or cables. 14122-2, it would be prudent to verify the safety requirements either by calculation or testing.
Your basket is empty. The clause goes on to provide details of how to test guard-rails and the steps of a stair. 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.

Clause 4 of Part 1 lists the most 14212-2 hazards to consider when determining the type and location of the means of access.
For testing stepladders, the reader is referred to ENLadders. The four parts are, in full:. Annex ARequirements for the design of anti-climb devices, is normative and should, therefore, be complied with often an Annex to a standard is informative only. One issue that is not addressed particularly well in the standard is the iwo of under what circumstances a permanent means of access is required, though an ISO risk assessment will help.
This part of BS EN ISO gives requirements for non-powered working 1412-22 and walkways which are a part of a stationary machine, and to the non-powered adjustable parts e. Annex A relates to methods for determining slip resistance and starts by stating that no international standard currently exists.
