Nebraska Administrative Code › Topic - STATE PATROL › Title 272 - NEBRASKA STATE PATROL › Chapter 9 - STORAGE OF EXPLOSIVES › Section 272-9-007 - Construction of Type 1 Storage Facilities

Current through June 17, 2024
A type 1 storage facility shall be a permanent structure: a
				  building, an igloo or Army-type structure, a tunnel, or a dugout. It shall be
				  bullet-resistant, fire-resistant, weather-resistant, theft-resistant., and well
				  ventilated.
007.01 Buildings
All building type storage facilities shall be constructed of
				  masonry, wood, metal, or a combination of these materials and shall have no
				  openings except for entrances and ventilation. Ground around such storage
				  facilities shall slope away for drainage.
007.01A Masonry Wall Construction. Masonry
				wall construction shall consist of brick, concrete, tile, cement block, or
				cinder block and shall be not less than 6 inches in thickness. Hollow masonry
				units used in construction shall have all hollow spaces filled with well-tamped
				coarse dry sand or weak concrete (a mixture of one part cement and eight parts
				of sand with enough water to dampen the mixture while tamping in place).
				Interior walls shall be covered with a non-sparking material.
007.01B Fabricated Metal Wall Construction.
				Metal wall construction shall consist of sectional sheets of steel or aluminum
				not less than number 14 gauge, securely fastened to a metal framework. Such
				metal wall construction shall be either lined inside with brick, solid cement
				blocks, hardwood not less than 4 inches in thickness, or shall have at least a
				6-inch sand fill between interior and exterior walls. Interior walls shall be
				constructed of, or covered with, a non-sparking material.
007.01C Wood Frame Wall Construction. The
				exterior of outer wood walls shall be covered with iron or aluminum not less
				than number 26 gauge. An inner wall of non-sparking material shall be
				constructed so as to provide a space of not less than 6 inches between the
				outer and inner walls, which space shall be filled with coarse dry sand or weak
				concrete.
007.01D Floors. Floors
				shall be constructed of a non-sparking material and shall be strong enough to
				bear the weight of the maximum quantity to be stored.
007.01E Foundations. Foundations shall be
				constructed of brick, concrete, cement block, stone or wood posts. If piers or
				posts are used, in lieu of a continuous foundation, the space under the
				buildings shall be enclosed with metal.
007.01F Roof. Except for buildings with
				fabricated metal roofs, the outer roof shall be covered with no less than
				number 26-gauge iron or aluminum fastened to 7/8 inch sheathing or 26 gauge
				aluminum, fastened to seven-eighths inch (.875") sheathing. Poured concrete
				roofs may be used on facilities on a case by case basis and must be of equal or
				greater strength and bullet resistance as other approved roffs.
007.01G Bullet-Resistant Ceilings or Roofs.
				Where it is possible for a bullet to be fired directly through the roof and
				into the storage facility at such an angle that the bullet would strike a point
				below the top of inner walls, storage facilities shall be protected by one of
				the following methods:
007.01G1 A sand-tray
				shall be located at the tops of inner walls covering the entire ceiling area,
				except that necessary for ventilation, lined with a layer of building paper,
				and filled with not less than 4 inches of course dry sand.
007.01G2 A fabricated metal roof shall be
				constructed of 3/16-inch plate steel lined with 4 inches of hardwood. (For each
				additional 1/16-inch of plate steel, the hardwood lining may be decreased 1
				inch.)
007.01H Doors.
				All doors shall be constructed of 1/4 inch plate steel and lined with 2 inches
				of hardwood. Hinges and hasps shall be attached to the doors by welding,
				riveting or bolting (nuts on inside of door). They shall be installed in such a
				manner that the hinges and hasps cannot be removed when the doors are closed
				and locked.
007.01I Locks. Each
				door shall be equipped with two mortise locks; or with two padlocks fastened in
				separate hasps and staples; or with a combination of mortise lock and padlock;
				or with a mortise lock that requires two keys to open; or a three-point lock.
				Locks shall be five-tumbler or five-blade. All padlocks shall be protected with
				1/4 inch steel caps constructed so as to prevent sawing or lever action on the
				locks or hasps. Semitrailer, tank trucks, and other mobile storage facilities
				locked with one steel case hardened five-tumbler padlock, having at least
				3/8-inch shackle diameter are determined to meet the necessary requirements of
				this section provided that hinges and hasps are securely fastened to the
				storage facility and that all locking hardware is secured rigidly and directly
				to the door frame. Accordingly, only one such Padlock will be required for each
				door or opening for semitrailer, tank trucks, and other mobile facilities; and
				such padlocks need not be protected by steel caps.
007.01J Ventilation. Except at doorways, a 2
				inch air space shall be left around ceilings and the perimeter of floors.
				Foundation ventilators shall be not less than 4 by 6 inches. Vents in the
				foundation, roof or gables shall be screened and offset. A side wall and door
				Ventilator that are screened and bullet-resistant can be substituted for
				foundation ventilators.
007.01K
				Exposed Metal. No sparking metal construction shall be exposed below the top of
				walls in the interior of storage facilities, and all nails therein shall be
				blind-nailed or countersunk.
