On the Britarch List two listers made the following comments regarding my enquiry:
Mark:
>The mystery appears to be - how can a 2m high unsupported and non-battered
>section face be considered safe for working beneath nowadays?
Rob:
>It can't. 1m is the guidance from the H&S executive I believe.
Rob and Mark are almost right. Working to IFA standards, which I am, it is
of course 1.2m.
May response was:
I hope you will note that the eastern side of the trench has been stepped
back to 1m. The northern side of the trench was shored with acro whilst work
was in process. This has now been removed to allow stepping back to 1m on
the northern side of the trench. The photographs were taken between the two
processes.
I hope this allows clarification.
Kindest regards,
Trevor
