(a) Section 842(j) of the Act and
§ 555.29 of this part require that the
storage of explosive materials by any
person must be in accordance with the
regulations in this part. Further, section 846 of this Act authorizes regulations to prevent the recurrence of accidental explosions in which explosive

explosive materials in a manner contrary to State or local law.
(b) The Director may authorize alternate construction for explosives storage magazines when it is shown that
the alternate magazine construction is
substantially equivalent to the standards of safety and security contained in
this subpart. Any alternate explosive
magazine construction approved by the
Director prior to August 9, 1982, will
continue as approved unless notified in
writing by the Director. Any person intending to use alternate magazine construction shall submit a letter application to the Director, Industry Operations for transmittal to the Director,
specifically describing the proposed
magazine. Explosive materials may not
be stored in alternate magazines before
the applicant has been notified that
the application has been approved.
(c) A licensee or permittee who intends to make changes in his magazines, or who intends to construct or
acquire additional magazines, shall
comply with § 555.63.
(d) The regulations set forth in

materials shall notify the authority
having jurisdiction for fire safety in
the locality in which the explosive materials are being stored of the type,

day on which storage of the explosive
materials commenced and in writing
within 48 hours from the time such
storage commenced.

three classes of explosive materials.
These classes, together with the description of explosive materials comprising each class, are as follows:
(a) High explosives. Explosive materials which can be caused to detonate
by means of a blasting cap when
unconfined, (for example, dynamite,
flash powders, and bulk salutes).
(b) Low explosives. Explosive materials which can be caused to deflagrate
when confined (for example, black powder, safety fuses, igniters, igniter
cords, fuse lighters, and ‘‘display fireworks’’ classified as UN0333, UN0334, or
UN0335 by the U.S. Department of
Transportation regulations at 49 CFR
172.101, except for bulk salutes).
(c) Blasting agents. (For example, ammonium nitrate-fuel oil and certain
water-gels (see also § 555.11).
