Analysis of Single Point Failure (SPF) modes in current fireworks firing systems yields an unacceptably high probability of failure resulting in an unplanned launch. The paper below summarizes the results of our research into the most common SPF sources and discusses solutions that can be implemented in firing systems to remove failure scenarios. In particular, a thorough redesign of the standard methodology for performing continuity testing can reduce the probability of inadvertent launch during testing.
