The response regulations of electrostatic discharge (ESD) conditions for firing device materials of an electric explosive device (EED) and its damages under an electrostatic environment were studied. The ESD process for discharge models under different high static voltage conditions was simulated and analyzed by the ESD models from Institute of Electrical and Electronic Engineers (IEEE) standard and Sandia laboratory standard. Energy values produced by discharge were determined and compared and analyzed with those of physical form transformation property of firing materials in a typical EED. The damage situation of ESD to a typical EED was predicted. Results show that peak discharge current increases with increasing the initial electrostatic voltage, while the other parameters of current waveform unchanges. For a typical firing device consisting of Ni-Cr bridge wire with a diameter of 40 μm and lead styphnat, the temperature in bridge wire can reach the melting point of tin solder, decomposition and ignition points of explosive at the initial voltage of 20 kV, making bridge wire fuse at 40 kV in IEEE standard. ESD model; while in Sandia laboratory standard ESD model, the temperature in bridge wire can reach the melting point of tin solder at 20 kV, decomposition and ignition points of explosive at 25 kV and melting point of bridge wire at 50 kV.
