Any joins had to be copper riveted and soldered. It must have worked

Excellent! And it kept the elephants away too, right? ;-)

You find out it doesn't work then it's too late. I reckon this one
must have worked okay or you would have heard the bang 10 miles away.
Possibly have debris rained on you 10 miles away too. There was a lot
of stuff from the Nobel works in that store.

others have pointed out to follow well-researched design codes. 'Course,

We put this one in according to instructions from the chief engineer
based on regulations in mines and quarries legislation. I haven't the
faintest idea how to design one. At the same time we installed an
alarm system too. Until then the place only had a padlock on it. More
innocent days then.

do such a thing. At least, no-one in *my* view of this NG. Ah, the
peace of a small but perfectly-formed killfile ;-)

I have a large kill file but I inhabit a political group too. I mostly
lurk in this one.

Yes.
I think they were up in Scotland.

I believe so - memory augmented by Google suggests both Ayrshire and
Dumfries. Presumably they put the plants in areas of relatively low
population density ;-)

Always seemed a touch amusing to have the Nobel Peace Prize instituted
to assuage old Alfred's guilt at inventing TNT, while ICI (which I believe
bought up his business interests) kept the name going with the more
original association!

The Stevenston ICI site (Ayrshire) is concerned with explosives manufacture.
Dunno if that's
its sole output though.
This ICI explosives site is built on the coast with lots of sand dunes
surrounding it (the folklore being that with sand
surrounding it German bombs were less likely to explode when dropped onto
sand during World War two).
