The recommended method to remove a misfire is to drill another hole at least 24 inches away from the original misfire location. This approach adheres to safety protocols and minimizes risks associated with handling explosives. By drilling a new hole, personnel can safely assess and manage the misfired area without disturbing the original explosive that failed to detonate.

The correct distance of at least 24 inches is crucial to ensure a safe separation from the potential hazards of the misfired explosive. This distance helps in reducing the chance of accidental detonation and allows for a more controlled response to the situation.

Other methods, while they may seem straightforward, introduce significant safety risks. Waiting for the misfire to clear on its own can lead to dangerous situations, as it is impossible to predict when or if the explosive will detonate. Using a crowbar to extract a misfired charge directly poses an imminent danger to personnel in the vicinity. Detonating another charge nearby is also extremely hazardous, as it could easily trigger the misfire and result in severe consequences. Thus, drilling a new hole provides a safer and more effective way to address a misfire.
