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