AMENDATORY SECTION(Amending WSR 05-12-033, filed 5/24/05, effective 6/24/05)

WAC 212-17-295   Public display -- General.   ((This section shall apply to the construction, handling, and use of Division 1.3G display or Division 1.4G consumer fireworks intended solely for public display. It shall also apply to the general conduct and operation of the display.)) The intent of this chapter shall be to provide requirements for clearances upon which the authority having jurisdiction shall base its approval of an outdoor fireworks display site. Where added safety precautions have been taken, or particularly favorable conditions exist, the authority having jurisdiction shall be permitted to decrease the required separation distances as it deems appropriate, upon demonstration that the hazard has been reduced or the risk has been properly protected. Where unusual or safety-threatening conditions exist, the authority having jurisdiction shall be permitted to increase the required separation distances as it deems necessary.

[Statutory Authority: Chapters 43.43 and 70.77 RCW. 05-12-033, § 212-17-295, filed 5/24/05, effective 6/24/05. Statutory Authority: RCW 70.77.250 and chapter 48.48 RCW. 82-22-068 (Order FM 82-10), § 212-17-295, filed 11/2/82.]


AMENDATORY SECTION(Amending WSR 05-12-033, filed 5/24/05, effective 6/24/05)

WAC 212-17-310   Public display -- Storage of shells.   (((1) As soon as the fireworks have been delivered to the display site, they shall not be left unattended and shall be kept dry.

     (2) All shells shall be inspected upon delivery to the display site by the display operators. Any shells having tears, leaks, broken fuses, or showing signs of having been wet shall be set aside and shall not be fired. After the display, any such shells shall either be returned to the supplier or be destroyed according to the supplier's instructions.


Exception: Minor repairs to fuses shall be allowed. Also, for electrically ignited displays, attachment of electric matches and other similar tasks shall be permitted.

     (3) All shells shall be separated according to diameter and stored in tightly covered containers of metal, wood, or plastic or in fiber drums or corrugated cartons meeting United States Department of Transportation specifications for transportation of fireworks. A flame-resistant tarpaulin shall be permitted to be used as a covering over the containers, if additional protection is desired.

     (4) The shell storage area shall be located at a minimum distance of not less than 25 feet (7.6 m) from the discharge site.

     (5) During the display, shells shall be stored upwind from the discharge site. If the wind should shift during the display, the shell storage area should be relocated so as to again be upwind from the discharge site.)) A ready box shall be a portable, weather-resistant container that protects contents from burning debris with a self-closing cover or equivalent means of closure required.

     (1) After delivery and prior to the display, all shells shall be separated according to size and their designation as salutes.

     (2) Any display fireworks that will be temporarily stored at the display site during the fireworks display shall be stored in ready boxes separated according to size and their designation as salutes. Tarpaulins shall not be considered as ready boxes.

Exception: For electrically ignited displays, or displays where all shells are loaded into mortars prior to the show, there is no requirement for separation of shells according to size, for their designation as salutes, or for the use of ready boxes.

     (3) During the performance of an outdoor fireworks display, ready boxes shall be located at a distance not less than twenty-five feet upwind from the mortar placements. If the wind shifts during a display, the ready boxes shall be located again to be upwind from the discharge site.

Exception No. 1: Where permitted by the authority having jurisdiction, alternate measures shall be taken.
Exception No. 2: Where there are no shells requiring storage during a display, such as for an electrically ignited display, no ready boxes shall be required.

AMENDATORY SECTION(Amending Order 90-02, filed 4/19/90, effective 5/20/90)

WAC 212-17-315   Public display -- Installation of mortars.   (((1) Mortars shall be inspected for dents, bent ends, and cracked or broken plugs prior to ground placement. Mortars found to be defective in any way shall not be used. Any scale on the inside surface of the mortars shall be removed.

     (2) Mortars shall be positioned so that the shells are carried away from spectators and into a clear area acceptable to the authority having jurisdiction.

     (3) Mortars shall be either buried securely into the ground to a depth of 2/3 to 3/4 of their length or fastened securely in mortar boxes or drums. In soft ground, heavy timber (e.g. 4-inch thick) or rock slabs shall be placed beneath the mortars to prevent their sinking or being driven into the ground during firing.


Exception: Boxed finales and finale racks.

     (4) In damp ground, a weather-resistant bag shall be placed under the bottom of the mortar prior to placement in the ground to protect the mortar against moisture.

     (5) Weather-resistant bags shall be placed over the open end of the mortar in damp weather to keep moisture from accumulating on the inside surface of the mortar.

     (6) Sand bags, dirt boxes, or other suitable protection shall be placed around the mortars to protect the operator from ground bursts. This requirement shall not apply to the down-range side of the discharge site.

     (7) Mortars shall be inspected before the first shells are loaded to be certain no water or debris has accumulated in the bottom of the mortar.

     (8) If steel mortars are placed in troughs or drums, the minimum distance from the mortar to the wall of the trough or drum shall be at least two times the diameter of the mortar.

     (9) If troughs and drums are used, they shall be filled with sand or soft dirt; in no case shall stones or other possibly dangerous debris be present.

     (10) If mortars which are generally considered not capable of generating dangerous flying debris are placed in troughs or drums, the minimum distance from the mortar to the wall of the trough or drum shall be at least equal to the diameter of the mortar. Commonly used mortars which are considered generally not capable of generating dangerous flying debris include paper and high density polyethylene mortars.

     (11) Whenever shells are to be chain fused, such as for barrages and finales, additional measures are required to prevent adjacent mortars from being repositioned in the event that a shell detonates in a mortar causing it to burst. For buried mortars, this shall be accomplished by placing the mortars with a minimum separation of four times their diameter. For mortars in racks this shall be accomplished by using mortar racks that have sufficient strength to successfully withstand such a failure.

     (12) When mortars are to be reloaded during a display, mortars of various sizes shall not be intermixed. Mortars of the same size shall be placed in groups and the groups must be separated from one another.

     To the extent practical, when mortars are to be reloaded during a display, groups of one size mortar should not be placed adjacent to mortars of only one inch different diameter. This will reduce the likelihood that shells will be loaded into oversized mortars. For example, an arrangement of mortar groups such as 5"-3"-6"-4" is greatly preferred over an arrangement such as 3"-4"-5"-6".

     (13) Mortars may be constructed of steel, paper or high-density polyethylene.

     (14) Steel mortars shall be deemed acceptable for use with all shells. Steel mortars shall be either seamed or seamless; however, seamed mortars must be placed such that the seam is facing either right or left as one faces the line of mortars. Steel mortars shall conform to the following:

MINIMUM MORTAR WALL THICKNESS (INCHES)

     The tensile strength of steel pipe shall be at least 40,000 psi.

     (15) Paper mortars shall only be used for discharge of single-break and double-break shells. A thirty second cooling period shall be allowed between firing and reloading of paper mortars. Paper mortars shall be constructed of convolute wound paper, except that spiral wound paper shall be permitted for 3-inch diameter mortars only. Paper mortars shall conform to the following:

     (18) A cleaning tool shall be provided for cleaning debris out of the mortars between firings.


Exception: When mortars are not to be reloaded during a display, there is no requirement for a cleaning tool.))

     (1) Prior to placement, mortars shall be inspected carefully for defects, such as dents, bent ends, damaged interiors, and damaged plugs. Defective mortars shall not be used.

     (2) Mortars shall be positioned and spaced so that shells are propelled away from spectators, over the fallout area, and to afford maximum protection to the shooter and loader. Under no circumstances shall mortars be angled toward the spectator viewing area.

     (3) Where mortars are to be reloaded during a display, mortars of various sizes shall not be intermixed. Mortars of the same size shall be placed in groups, and the groups shall be separated from one another.

     (4) Mortars of any type six inches in diameter or less shall be permitted to be reloaded and fired up to seven times during a performance.

Exception: There shall be no limit to the number of times a steel mortar six inches or less is permitted to be reloaded.

     (5) Mortars shall be positioned to afford protection to the spectators and display personnel.

     (6) Mortars shall be inspected before the first shells are loaded to ensure that no water or debris has accumulated in the bottom of the mortar.

     (7) Mortars shall be of sufficient strength and durability to fire the aerial shells and be used safely.

     (8) Paper, HDPE, and fiberglass mortars are among the types of mortar that shall be permitted to be used.

     (9) Cast iron, stove pipe, corrugated culvert, clay, bamboo, and wood shall not be used to make mortars.

     (10) Metal mortars shall be either seamed or seamless; however, seamed mortars shall be placed so that all seams face either right or left when viewing the line of mortars.

     (11) Steel mortars used to fire single break salute shells shall be buried according to WAC 212-17-321.

     (12) Mortars shall be of sufficient length to cause aerial shells to be propelled to safe heights.

     (13) The dimension of the inside diameter of the mortar shall be conspicuously painted or otherwise marked on the top of the mortar.

Exception: Designation of the inside diameter shall not be required for outdoor fireworks displays fired under the direct control of a professional fireworks display company.
