I kind of go along with the comments that this should not be parked
under a grandstand, especially when occupied. If this thing is moved,
I would look into some form of self-contained protection, such as a
dry chemical. But the purpose would only be to keep the combustible
construction from igniting the fireworks. Why don't they get a
container and put it on a trailer? At least that is all metal and
would eliminate the wood construction.

Subject: Explosives
I have a customer who stores a quantity of less than 2 # of Class
1.4G explosives. These explosives are comparable to fireworks. The
1.4G is stored in a metal cabinet, not rated. The storage unit is 8
foot wide x 8 foot high x 12 foot long. The construction is wood
frame, plywood floor, wood panel interior, and metal outside. If
this sounds like a job trailer, your are right. The trailer is
parked under a grandstand. the steel/wood grandstand is protected
with a dry system, under the grandstands. Other contents are
ordinary combustibles, wood, paper, cardboard.
Upon occasion, the trailer is moved to other locations for
shows. Then the trailer is parked under the grandstand. unless the
trailer is put in the exact same spot, connection to the sprinkler
system will be difficult. Can the flex head work for this
application? As the 1.4G is in a cabinet, I would feel better with
a sprinkler head in the cabinet, with a head or heads protecting the trailer.
Any suggestions?

Oops, I was not clear enough on the "these explosives are comparable
to fireworks" I did not mean the arial rockets. I meant the kind
you get from the tents for the kids to fire off for the Fourth of
July. Maybe I should have said "pyrotechnics", as these are like
you might see at a rock concert. But keep the comments coming. When
I told the FM I would post on the Sprinkler Board, he was relieved
to have the input from the Board.
