Loading and Firing of Shells
(1)
Shells must be carried from the storage area to the discharge site only by their bodies, never by their fuses.(2)
Shells must be checked for proper fit in their mortars prior to the display.(3)
When being loaded into the mortars, shells must be held by their fuses or lowering cord if provided and carefully lowered into the mortar. At no time may the person loading the shells place any part of their body over the mouth of the mortar.(4)
The person loading shells must be reasonably certain the shells are properly seated in the bottom of the mortars.(5)
Shells must not, under any circumstances, be forced into a mortar too small to accept them. Shells that do not fit properly into the mortars must not be fired.(6)
The safety cap protecting the fuse must not be removed until immediately before the shell is to be fired.(7)
Shells may be ignited by lighting the tip of the fuse with a fusee, torch, portfire, or similar device. The operator must never place any part of their body over the mortar at any time. As soon as the fuse is ignited, the operator must turn away from or retreat from the mortar area.(8)
The first shell fired must be observed carefully by the operator to determine that its trajectory is such that the shell functions over the fall-out area and that any dangerous debris or unexploded shells will land in the fall-out area. The operator must determine whether or not to begin the display and must monitor the display continuously to determine if the display continues to meet all requirements for the continuance of the display.(9)
The display must be interrupted and the mortars must be re-angled or repositioned as necessary for safety any time during a display. In the case of a barge, the display must be interrupted and the barge must be repositioned as necessary for safety any time during display.(10)
In the event of a shell failing to ignite in the mortar, the mortar must be marked in some manner to indicate the presence of an unfired shell, and the mortar may not be reloaded or reused so long as the misfired shell remains. Immediately following the display but no sooner than 15 minutes after the attempted firing, if the shell still has not fired, the mortar must be cautiously flooded with water and let stand for a minimum of five minutes before it is cautiously emptied of the shell. The operator must be knowledgeable in the proper disposal methods.(11)
It is the responsibility of the person igniting the aerial shells to detect when a shell does not fire from a mortar. That person must warn others in the area and immediately cause the mortar to be marked to indicate the presence of an unfired aerial shell.(12)
Manual re-ignition of chain fused aerial shells may only be attempted at properly installed ignition points.
