Unusual Accidents Caused by ESD

For precise control and timing of a blast, people use electric detonators. Most of these contain a fine metal “bridgewire,” that heats to the required burning temperature when electric current passes through it. Users should be careful. Stray voltage can fire these detonators. Some designs are particularly susceptible to electrostatic-discharge (ESD). We will discuss some of the accidents we have encountered in our forensic work. We will recommend specific safe procedures for handling and firing these devices.
