HPTA High Pressure Safety Code - Pressure Test Barricades

[rkinga2]

I'm trying to find a copy of the HPTA High Pressure Safety Code, put out by the High Pressure Technology Association in the UK in the 70's. Any hints or clues? I have a nice description of it in the 1975 High Pressure Engineering conference proceedings from IME, but am running into a brick wall trying to find it.
It apparently has a nice discussion of providing barricades for protection of operators during accidents w/ high-pressure equipment. Does anyone know of other references on this subject? I'm looking at a barrier to go around a pressure test room (not very high pressure, but enough to make folks nervous). Thanks

I really have nothing constructive to add, but you mentioned pressure test, and that always makes me nervous.

A county or two would make a great barrier.
