stairs for plants and machines

[gil]

Hi.

so that the stairs, to access technical rooms or machinery, are not required to comply with the common rules for the stairs, summarized in: dm 14giu89 n°236, dlgs 9 April 2008 n°81, ntc 08.

in the new machinery directive (Directive 2006/42/ce of 17 May 2006, introdotta con dlgs 27 gennaio 2010, n. 17. I have not found precise prescriptions such as parapet size, step sizes, etc. I have linked the mentioned rules.
The directive also seems to prescribe the procedures for marking, but not how to make the product.

I am therefore asking for clarification on this matter. for a scale of access to technical rooms such as an electric power plant, a purification plant etc., in which only technical personnel will pass, what prescriptions should they comply? I believe that the uni en iso 14122/2012 has something to do with it but I have no way to see it, and on the site uni nothing comes out.

thanks for any suggestions

the en 14122-x are harmonized according to 2006/42/ce and therefore are means of access to the machinery and if you follow it you are serene.
I don't know the ntc well but I often designed accesses with 14122 but not connected to machines.
You can't see her if you don't have a subscription to the unit. It's normal!
