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. Stairways, stepladders and guard-rails Withdrawn. The Amber document status indicator indicates that some caution is needed when using this document – it is either: Stairs, stepladders and guard-rails ISO The four parts are, in full:.

In other words, when designing and specifying means of access, consideration should 14122- given to preventing unauthorised access. To maintain its compliance with the standard, Kee Safety has modified the design of its Kee Gate range of safety gates.

Procter Machine Guarding offers free Machine Guarding Compliance Surveys of standalone machinery 14122–3 assemblies of machines, old or new, and can also assess permanent means of access. Clause 5Specific requirements of ladder systemsprovides extensive information relating to ladder design, including the profiles and dimensions of rungs round rungs are not permitted.

Free to use BIM project management tool provides step-by-step help to define, manage and validate responsibility for information development and delivery at each stage of the asset life cycle in level 2 BIM projects. If the designer chooses to verify the safety requirements by calculation, the information relating to the test methods must be taken into account so that the two verification methods are comparable.


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

There is no option in the Annex for verifying the safety requirements by calculation. The four parts are all B-Type standards, meaning they deal with specific aspects of machinery safety and can be applied to a wide range of categories of machinery. Document Status Indicators The Green document status indicator indicates that the document is: 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.

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. 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.

This part of BS EN ISO gives requirements for non-powered stairs, stepladders and guard-rails which are a part of a stationary machine, and to the non-powered adjustable parts e. However, great care should be taken with ribbed ramps, bearing in mind that subclause 4.

Another point to note from the definitions is that handrails must be rigid, which excludes the use of ropes, chains or cables. Kee Safety has also added a mid rail, minimising the gap between the top of the gate and the b rail.

I accept the privacy policy. Clause 6, Verification of safety requirementsappears to contradict subclause 5.

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 risk assessment will help. Their committees work with the manufacturing and service industries, government, businesses and isso to facilitate the production of British, European and International standards. It will be used by: Clause 5 lists the general requirements for gs and construction of means of access.

The clause goes on to provide details of how to test guard-rails and the steps of a stair.

However, see Em 6 below. Suitable for internal and external use, Kee Gate can be implemented on ladder and stair access points, as well as roof hatches, walkways, and roof tops. It states that a guardrail should be fitted when the height of a fall could exceed mm; the specified guardrail needs to meet a number of dimensional requirements and a self-closing gate should also be used.
