272 Neb. Admin. Code, ch. 9, § 003
For purpose of these regulations, there shall be five types of storage facilities. These types, together with the classes of explosive materials which shall be stored therein, are as follows:
Permanent storage facilities for the storage of high explosives which can be caused to detonate by means of a blasting cap when unconfined, (for example dynamite, flash powders, and bulk salutes). Other classes may also be stored therein.
Portable indoor and outdoor storage facilities for the storage of high explosives which can be caused to detonate by means of a blasting cap when unconfined, (for example dynamite, flash powders, and bulk salutes). Other classes may also be stored therein.
Portable outdoor facilities for the temporary storage of high explosives which can be caused to detonate by means of a blasting cap when unconfined, (for example dynamite, flash powders, and bulk salutes), while attended (for example, a "day-box"). Other classes may also be stored therein.
Facilities for the storage of low explosive materials which can be caused to deflagrate when confined, (for example, black powder, safety fuse, igniters, ignitor cords, fuse lighters, and "special fireworks" as defined as Class B explosives by US Department of Transportation regulations in 49 CFR Part 173, except bulk salutes). Blasting agents (ammonium nitrate-fuel oil) may also be stored in a type 4 storage facility. Detonators that will not mass detonate may also be stored in a type 4 storage facility. No high explosives may be stored in a type 4 storage facility.
Facilities for the storage of blasting agents. No high explosives may be stored in a type 5 storage facility.
