What is the priming requirement of the SF Method?

The priming requirement of the SF Method is that it must be primed at both ends. This is crucial because the SF Method involves the use of two explosive charges that need to be detonated simultaneously for effective results. By priming at both ends, the method ensures that both charges are adequately initiated, leading to a more uniform and reliable explosion. This is particularly important in applications involving unexploded ordnance, where precision and control are essential for safety and effectiveness in neutralizing potential hazards. This priming approach helps to create a balanced detonation, reducing the risk of misfires or incomplete initiation that could occur if only one end were primed or if priming were not performed at all.
