1) Shooter must STOP (or be stopped) immediately due to the seriousness of the SAFETY issue involved.
This would NOT constitute "RO impeding/interference" in handling a shooter's equipment failure;
therefore there would be NO GROUNDS for a restart/reshoot.
Precedent exists regarding the handling of a suspected "squib" during stage engagement.
2) If the shooter is able to remedy the issue SAFELY, s/he may continue the stage after resolution.
An RO should be allowed
