Hi guys,
As we all no doubt know, lanyards should be connected to a suitable and tested eyebolt (or similar) when using lanyards and harnesses. I am familiar with the requirements of BS 7883:2005 (Code of practice for the design, selection, installation, use and maintenance of anchor devices conforming to BS EN 795), but I have a problem on site.
The problem is that we are working on a multi-storey development, and are about to enter a riser area that has exposed openings that drop a substantial distance. There are 22 such areas at present, but these will all change as the job progresses - so getting eyebolts inserted and tested will just not be practicable to do.
I am of the opinion that structural steels (which are available for use and in close proximity) are more than adequate for the task. I am in the process of compiling a risk assessment and specific method statement for this task (as well as an extract plan), and wondered if anyone had any previous experience of doing this (or not doing it, as the case may be!)?
I have read the usual documentation on the subject (HSE publications, WAHSA documents) and, surprise-surprise, no-one seems to make any mention of it.
Any advice welcome.

Your proposal is no different IMHO than that routinely applied by scaffold erectors, who clip on to the temporary structure as required?

What you propose is perfectly legal and common practice provided the "things" being connected to are of suitable strength - which in current standards is something that will withstand a 12kN dynamic impact without allowing the person to fall (12kN is 1200kg), and we're talking about a split-second force not a static weight so we don't care about SWLs or safety factors - if the steel can physically keep the person off the ground even if it bends or tears, it's safe to use.
There's absolutely no need to install certified anchorages if you can find a structural element that's suitable - 99% of people who use fall arrest lanyards will never see an EN795 eyebolt in their lives!
If you're having problems finding anchor points close to where you're working, then remember lanyards are not the only option (and actually tend to be the worst). In something confined and vertical like a riser I'd be looking at a temporary vertical lifeline, based on a rope and a fall arrest device such as a Rocker/StickRun/ASAP, which can be tied to a single strong point at the top of the shaft and allows complete freedom of movement and hands-free protection. Using an extended system such as a rope, wire or retractable block makes your requirements for rescue planning easier too, as nobody has to climb into the riser to unclip a casualty.
