Height of wet risers

The point to remember here is that BSI don't write regulations. That's a Job for the Government.

There's some good stuff produced by BSI and there's some utter nonsense (bit like the regs maybe).

Approved Docs have statutory status BS's don't.

Of course, once you get into risk assessment etc it all gets a bit grey but the Determination on AFD in Hotels helps with that, a bit, ish.
