Hello,
I have a blank memory moment & hope someone would be kind enough to help:
the Work at Height Regs mentioned a minimum 950mm height for existing edge protection, new edge protection are 1100mm minimum. Where/which documentation is 1100mm mentioned in?
Thank you
Bernie

WAH 2005 still applies. So, working on a roof or scaffold the 950mm height still applies.
The 1100mm is the Building Regulations Part K
https://www.gov.uk/gover...181/BR_PDF_AD_K_2013.pdf
I'm not an expert, but I suppose when you BUILD something permanent the edge protection e.g. banisters, landings etc the minimum height is now 1100mm
Are you saying WAH providers are now making temporary edge protection devices at 1100mm?

"Are you saying WAH providers are now making temporary edge protection devices at 1100mm?":
Not saying that at all, just in the middle of writing reply to a customer regarding why their system they want for working on flat roof is not safe.
I knew about the 950mm but came across 1100mm height & was wondering where that came from...
Thank you very much for taking the time to answer it helps a lot.

I never understood when the WAH Regs came in and the size went from 910 - 950 they didn't standardise on 1100 for consistency (Building regs obviously not going to change......) Maybe they thought the 'jump' was too big?
Why is it 'safe' for the guy building a balcony to have one size, but the end user needs it higher? Odd.
I covered the full range in my patent application, just in case it changes in the future......

I believe that the minimum height of edge protection handrail changed do to the average height of the population getting taller therefore the center of gravity of the average person is higher. Not sure why the difference in the temporary handrail height and a a fixed handrail are different though.

With the building regs, if there was a change it is not retrospective, so the landing rail in my 1985 house does not need to change.
If the WAH guidelines on barrier and guard rails were to change then would there be a requirement to discard old edge protection devices ?
Businesses would find such a requirement unreasonable, as it would also affect height of guard rails on MEWPs etc?

System scaffolds manufactured prior to the introduction of WAH Regs '05 were still allowed to be used with the old 910mm top rail height. I don't think there was a time limit on their use, but all new equipment had to comply with the then current standard.
I have to say I never measured any to check if much was still in use!
Tube and fit, of course, was not an issue
