What does "non-electric initiation" refer to in explosives management?

"Non-electric initiation" refers to the process of detonating explosives without the use of electric devices. This approach utilizes alternative means for initiating a detonation, such as shock tubes or fuses, which do not rely on electrical circuits.

In explosive safety management, non-electric methods are favored in certain scenarios because they reduce the risk of unintended detonations caused by stray electrical currents or static electricity. Such processes enhance safety, particularly in environments where electrical interference might pose a significant hazard.

The other methods mentioned in the answer choices involve either direct electrical means or manual systems that may still incorporate electrical components, making them unsuitable under the definition of "non-electric initiation."
