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. Clause 7Specific requirements applicable to guard-railsstates that guard-rails shall be installed when the height of the possible fall exceeds mm, if the gap between the platform and machine structure exceeds mm or if the protection provided by the structure is not equivalent to a guard-rail.
Clause 8Verification of safety requirementsgives a choice of testing or calculation. Who is this standard for? However, the same subclause states that the minimum height of the guard-rail shall be mm, so it appears ios the former may be a typographical error and the height of the handrail should be greater than or equal to mm.
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. A 141222-2 point to note is that ISO Part izo is in preparation, which will deal with permanent means of access on mobile 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.
Furthermore, three-point contact needs to be maintained except for very brief periods eg starting a screwheavy 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. 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 io.
Clause 4Selection and design of ladder systems, provides some of the information required by the 1422-2, but more is contained in Clause 5.

For the purposes of BS EN ISOpermanent means of access are working platforms, walkways, stairs, stepladders, guard rails and fixed ladders. Permanent means of access to machinery. Annex B lists the significant technical changes between ISO 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.
You may find similar items within these categories by selecting from the choices below:. 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.
Your basket is empty. 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. 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.
For example, rather than require an access point so that lubrication points can be reached, lubrication points should be made accessible from ground level or a lubrication circuit and pump could be installed.
However, great care should be taken with ribbed ramps, bearing in mind that subclause 4. If guard-rails are being installed alongside platforms or walkways, Part 3 will have to be used in conjunction with Part 2 as well.

It specifies minimum requirements that also apply when the same means of access is required as the part of the building or civil construction e.
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.
Nevertheless, it would be prudent to verify isp safety requirements either by calculation or testing.

Clause 4 of Part 1 lists the most significant hazards to consider when determining the type and location of the means of access. Working platforms and walkways Status: Procter Machine Guarding offers free Machine Guarding Compliance Surveys of standalone machinery and assemblies of machines, old or new, and can also assess permanent means of access.
