This part of BS EN ISO gives requirements for ios working platforms and walkways which are a part of a stationary machine, and to the non-powered adjustable parts e.
Furthermore, a permanent means of access can prove to be very cost-effective compared with the cost of erecting scaffolding on multiple occasions. Clause 5Specific requirements applicable to stairsprovides further information for designing stairs.

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 iwo. 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.
Clause 4 of Part 1 lists the most significant hazards to consider when determining the type and location of the means of access. 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.
Nevertheless, it would be prudent to verify the safety requirements either by calculation or testing. However, great care should be taken with ribbed ramps, bearing in mind that subclause 4. It will be used by: The clause goes on to provide details of how to test guard-rails and the steps of a stair. 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.
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. Clause 6Specific requirements applicable to step laddersprovides similar details to those in Clause 5. Another point to note from the definitions is that handrails must be rigid, which excludes the use of ropes, chains or cables.
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. 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.

The four parts are, in full:. This is Part 2 in a series of four international standards which define general requirements for safe access to machinery. 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.

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.

The previous editions cease to provide a presumption of conformity to the Machinery Directive on 31 December Annex C lists the significant technical changes between ISO 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.
Conveyor Guarding Explaining the hazards associated with conveyors, regulations and standards, and how to safeguard conveyors without adversely affecting productivity. Clause 6, Verification of safety requirementsappears to contradict subclause 5. Annex A gives examples of changes that can be made to the machine or system to make better access possible.
