5\. 5\------------------------------------------------------------------------\1\ Net weight is the weight of all pyrotechnic compositions, and
explosive materials and fuse only.\2\ The distances in this column apply only with natural or artificial
barricades. If such barricades are not used, the distances must be
doubled.\3\ While consumer fireworks or articles pyrotechnic in a finished state
are not subject to regulation, explosive materials used to manufacture
or assemble such fireworks or articles are subject to regulation.
Thus, fireworks process buildings where consumer fireworks or articles
pyrotechnic are being processed shall meet these requirements.\4\ A maximum of 500 pounds of in-process pyrotechnic compositions,
either loose or in partially-assembled fireworks, is permitted in any
fireworks process building. Finished display fireworks may not be
stored in a fireworks process building.\5\ A maximum of 10 pounds of flash powder, either in loose form or in
assembled units, is permitted in any fireworks process building.
Quantities in excess of 10 pounds must be kept in an approved
magazine. [T.D. ATF-293, 55 FR 3723, Feb. 5, 1990, as amended by T.D. ATF-400, 63 FR 45004, Aug. 24, 1998]
