Lead styphnate is a poor initiating explosive which when dry is very sensitive to friction and impact, to electrostatic discharge, and to flame. Its main use is as an additive to lead azide to improve flame sensitiveness (see p. 101). When pressed to a density of 2-6 g ml-1 it has a velocity of detonation of4900 m s l.

Electrostatic discharge Static or electrostatic discharge may be sufficient to initiate detonation in a number of explosives under some circumstances. As a result, the handling of explosives and pyrotechnics, most of the time, is unsafe and requires electrical grounding of working tables and operators. 

Diamino-2,2, 4,4 6,6 -hexanitrodiphenyl (DIPAM) [Structure (2.30)] is extremely insensitive to electrostatic discharge, requiring more than 32 kj for initiation. In addition, it has good thermal stability (m.p. ca. 304 °C) and has been used to achieve stage separation in space rockets and for seismic experiments on the moon in a manner similar to HNS [74]. 

The explosive was exhaustively characterized for thermal behavior, impact sensitivity and electrostatic discharge sensitivity etc. Based on this data, CP has been described as much less sensitive to accidental initiation than primary explosives such as LA but at the same time, initiation grows rapidly to detonation when properly confined. Its performance evaluation in a test detonator or hardware indicates that CP can replace primary explosives in many hot wire detonator applications especially if safety considerations are of prime importance [239].

A special type of an electrostatic discharge test is one which seeks to determine dust explo-sibility (Ref 18, pp 2—13). This author has never seen any data which proves this test to be of any particular value in establishing a threshold initiation level of certain pyrot powders such as flash compns and their ingredients such as metallic Zr powder...
