Hi please can someone advise?

We need a rope access company to abseil down our building to investigate a leak. They want to utilise the flagpole and supporting brackets which is on the roof as a primary anchor. Should this be tested prior to them doing this?

But I'd also go with the default of telling them they can't. Most abseilers are not structural engineers but, my gosh, they seem to think that technical roping abilities grant them such powers.

Anchor points need to be unquestionably reliable (structural steel etc.) if you aren't going to test them. Brackets etc. that are bolted into a substrate of any kind for a totally different purpose will not fit the bill.

So, even though there will be secondary anchor, each anchor needs to be able to independently meet the required standards - and not just to hold a single 80kg abseiler - but also to withstand the dynamic load of a fall and then support at least two people during potential rescue.

So yes, test away assuming you/they can find the kit to do so. Bearing in mind that this will apply a lateral load to the flagpole and brackets which, if they're not strong enough, might damage the fixings etc.

Might be cheaper to install eyebolts, investigate other potential anchors in the vicinity, and/or look at deadweights on appropriate roof surface (although also fraught with potential pitfalls!)
