How many sheathed explosives may be fired at once?

The correct answer is that no more than three sheathed explosives may be fired at once. This limit is rooted in safety regulations and best practices in the handling and use of explosives.

By restricting the number to three, the risk of an uncontrolled explosion or the potential for excessive shockwaves is minimized, which is crucial in preventing accidents and ensuring the safety of personnel and the surrounding environment. This regulation helps to control the blast effect and allows for better management of the sequence and timing of detonations.

Maintaining strict limits on the number of sheathed explosives fired simultaneously is an essential part of operational procedure in the field, ensuring that safety standards are upheld to protect the workers and the public.
