Group 1 Medical locations - can an EBB be used to serve more than a single room?

Simon Bourke

Under BS 7671 is it appropriate to treat multiple single patient locations as one medical local location with a shared EBB?

For example[le where there are a number of rooms with similar clinical procedures, adjacent to each other, can an EBB share a number of rooms to avoid having an EBB  in each room, see image below?

    Taking a step back - supplementary bonding work best with a small group of closely connected items - as long as two items are out-of-reach of each other, there's little to be gained by having them within the same bonding zone - whereas the larger the zone and the more external influences there are pulling up or down at the extremities, the worse the overall effect. Where BS 7671 set limits, they need to be able to include the worst case situations (say a large ward or barn like casualty clearing station) but that's not to say that better results could, and arguably should, be achieved in less difficult situations. Engineering judgement rather than just minimal BS 7671 compliance.

    Also, in a situation like the building  plans in the original post above, you'd probably not want a mix of sockets or fixed kit in the same room that was split over more than one bonding point - leading you to one big zone, which might really be sub-zones with the EBBs very solidly inter-connected, or zones with a hard stop at walls floor and ceiling so you cannot find a person with one foot in each of 2 unconnected zones as it were.

    Again, the standards may not be explicit, but that does not mean the overarching aims cannot be achieved with some informed design choices.
