Annex B informative illustrates the main dimensions of a fixed ladder equipped with a safety cage. Toeboards should have a 14122-33 height of mm and their distance from the walking surface must not exceed 10 mm. Take the smart route to manage medical device compliance. The four parts are, in full:. Stairs, stepladders and guard-rails Status: However, the 141223 of the standard specifically excludes powered means of access lifts, escalators or other devices designed to move persons between levels.
The standard also states that the gate should 14122- be locked, but held in closed position, and should be designed to open easily and closed with a firm 14122–3, preventing users pushing against the gate and potentially falling through the opening.
Machine manufacturers small, medium and large enterprises Health and safety bodies regulators, accident prevention organizations, market surveillance, etc.
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.
We would like to thank you all for your continued support and wish you all a Merry Christmas and a Happy New year! Clause 5 lists the general requirements for design and construction of means of access. Our KeeLine fall protection solution provides fall arrest where guardrails are not suitable.
Clause 6Specific requirements applicable to step laddersprovides similar details to those in Clause 5. Our site requires cookies to function, click here for more information Ok, thank you.
With Christmas just around the corner, make sure to decorate with caution.
Available with standard ‘U’ bolts for fixing to uprights of 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. A final point to note is that ISO Part 5 is in preparation, which will deal with permanent means of access on mobile machinery. The previous editions cease to provide a presumption of conformity to the Machinery Directive on 31 December You may experience issues viewing this site in Internet Explorer 9, 10 or Kee Safety has also added a mid rail, minimising the gap between the top of the gate and the bottom rail.
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. Free Ergonomics Guidance European Commission publication Guidance on the application of the essential health and safety requirements on ergonomics.
The rules for the construction of permanent edge protection systems listed below are derived primarily from EN ISO ENMinimum Gaps to Avoid Crushing Explaining the requirements of the standard for minimum gaps to prevent crushing. Sign up to our newsletter for regular email updates on the latest Guarding news and products. As with guards, when considering means of access the first approach should be to design-out the risks.
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. Clause 8Verification of safety requirementsgives a choice of testing or calculation. In other words, when designing and specifying means of access, consideration should be given to preventing unauthorised access.
The four are all B-Type standards, meaning they deal with specific aspects of machinery safety and can be applied to a wide bx of categories of machinery. For testing stepladders, the reader is referred to ENLadders. The clause goes on to provide details of how to test guard-rails and the steps of a stair. Furthermore, a permanent means of access can prove to be very cost-effective compared with the cost of erecting scaffolding on multiple occasions.
It may seem strange that permanent means of access to machinery are related to machine guarding but, in fact, they are.

Clause 8Verification of safety requirementsgives a choice of testing or calculation. However, the same subclause states that the minimum height of the guard-rail shall be mm, so it appears that the former may be a typographical error and the height of the handrail should be greater than or equal to mm.
The UNI EN Standard also 41122-3 that the parapets should be resistant to harmful environmental agents corrosive atmosphere, humidity, cold, etc. 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.

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. The previous editions cease to provide a presumption of conformity to the Machinery Directive on 31 December As well as providing requirements for guard-rails on platforms, stairs and stepladders, Clause 7 also gives details for toe plates, self-closing gates and mezzanine gates.
Where there are hazards 144122-3 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. For many years, chains, bars and sliding link tubes have been the method of protection for safe access. With a heavy duty PVC base weighing 25kg, our Kee Mark system is protected even during severe weather conditions.
As with guards, when considering means of access the first approach should be to design-out the 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.
