     In addition to the definitions in chapter 70.77 RCW and this rule, the following definitions apply to this appendix:

     Barricade. A natural or artificial barrier that will effectively screen a magazine, building, railway, or highway from the effects of an explosion in a magazine or building containing explosives. It shall be of such height that a straight line from the top of any sidewall of a building or magazine containing explosives to the cave line of any magazine, or building, or to a point twelve feet above the center of a railway or highway, will pass through such natural or artificial barrier.

     Natural barricade. Natural features of the ground, such as hills, or timber of sufficient density that the surrounding exposures that require protection cannot be seen from the magazine or building containing explosives when the trees are bare of leaves.

     Artificial barricade. An artificial mound or revetted wall of earth of a minimum thickness of three feet.

     Breakaway construction. A general term which applies to the principle of purposely providing a weak wall so that the explosive effects can be directed and minimized. The term "weak wall" as used in this code refers to a weak wall, weak wall and roof, or weak roof.

     The term "weak wall" is used in a relative sense as compared to the construction of the entire building. The design strength of a "weak wall" will vary as to the building construction, as well as to the type and quantity of explosive or pyrotechnic materials in the building. The materials used for "weak wall" construction are usually light gauge metal, plywood, hardboard or equivalent lightweight material, and the material is purposely selected to minimize the danger from flying missiles. Method of attachment of the weak wall shall be such as to aid the relief of blast pressure and fireball.

     21. Storage buildings for Division 1.4G fireworks may be a building, igloo, box, trailer, semi-trailer or other mobile facility. They shall be constructed to resist fire from an outside source and to be weather-resistant and theft-resistant.

     22. Storage buildings for Division 1.4G fireworks shall be vented, or in the alternative, shall be constructed in such a manner that venting will occur by yielding of weaker parts of the structure under pressure generated by burning fireworks.

     23. All storage buildings shall be equipped with locking means for all openings.

     24. All doors shall open outward and all exits must be clearly marked. Aisles and exit doors shall be kept free of any obstructions.

     25. Only dust-ignition proof type electrical fixtures shall be used and wiring shall comply with Section 502-4(b) of the National Electrical Code. No wall receptacles are permitted. All light fixtures must have guards.

     26. An outside master electrical switch shall be provided at each storage building where electricity is used.


3. Storage building operations

     31. Storage.

     a. Storage buildings shall be in the charge of a competent person at all times who shall be at least 21 years of age, and who shall be held responsible for the enforcement of all safety precautions.

     b. Doors shall be kept locked, except during hours of operation.

     c. Safety rules covering the operations of storage buildings shall be posted.

     d. Containers shall be piled in a stable manner.

     e. Division 1.4G fireworks shall be stored in their original packaging and in unopened cases or cartons so as to take advantage of the insulation provided by such packaging; provided, however, unpackaged fireworks which have been returned by retailers may be temporarily retained in bins for repackaging.

     f. Tools used for opening containers of Division 1.4G fireworks shall be constructed of nonsparking material, except that metal slitters may be used for opening fiberboard containers.

     g. Storage buildings shall be regularly swept, kept clean, dry, free of grit, paper, empty used packages and rubbish. Brooms and other cleaning utensils shall not have any spark-producing metal parts. Sweepings shall be properly disposed of.

     h. When storage buildings need interior repairs, all fireworks shall be removed therefrom and the interior cleaned.

     i. In making exterior storage building repairs, when there is a possibility of causing sparks of fire, the fireworks shall be removed from the storage building.

     j. Fireworks removed from a storage building under repair shall either be placed in another storage building or placed a safe distance from the storage building, where they shall be properly guarded and protected until repairs have been completed. Upon completion of repairs, the fireworks shall be promptly returned to the storage building.

     32. Miscellaneous safety precautions

     a. Smoking, matches, open flames, spark-producing devices and firearms (except firearms carried by authorized guards) shall not be permitted inside of or within 25 feet of storage buildings.

     b. The land surrounding storage buildings shall be kept clear of brush, dried grass, leaves and similar combustibles for a distance of at least 25 feet, unless equivalent protection is provided.

     c. Smoking shall not be permitted in storage buildings or within 25 feet of the storage building. There shall be conspicuously posted signs with the words "FIREWORKS -- NO SMOKING" in letters not less than four inches high.

Note 1: This table does not apply to separation distances at fireworks manufacturing buildings, and magazines for storage of Division 1.4G fireworks and storage buildings for Division 1.4G fireworks. Those separation distances are given in Table 2.

Note 2: Net weight is the weight of all pyrotechnic and explosive composition and fuse only.

Note 3: See definitions of "passenger railways," "public highways" and "inhabited buildings."

Note 4: Division 1.3G fireworks processing buildings and Division 1.3G fireworks magazines, including buildings located on the property of a fireworks plant shall be separated from passenger railways, public highways, and inhabited buildings by a minimum distance of 200 feet except that the separation from hospitals, schools and bulk storages of flammable liquids or flammable gases shall be by a minimum distance of 500 feet.

Note 5: The separation distances shall apply to all Division 1.3G fireworks except salutes. The separation distances in Table 3 shall apply for salutes. When salutes and Division 1.3G fireworks are stored in the same magazine, the net weight of salute is applied to Table 3 and the net weight of Division 1.3G fireworks, including the net weight of salutes, is applied to Table 1. Whichever distance is the greater shall determine the separation distances of the magazine.

Note 6: All distances in Table 1 are to be applied with or without barricades or screen-type barricades.
