Fantastic and thanks for posting that. I loved it and I've forwarded it to many friends.
Why the H&S concerns, though? It makes clear in the video that there is a compromise between stopping to hook on and the "perceived" safety of being hooked on. The engineer had the harness and the hook readily available, he was allowed to use his personal judgement to decide when to use them. The UK version would probably have required 3 H&S managers to climb with them, and 2 more to carry the site safety reports.
