Detonators being fired simultaneously at the edges of the high explosives causes implosion that exerts pressure on the fissionable material, causing it to compress into a critical mass that results in nuclear explosion. In an event in which the high explosive, itself, is accidentally ignited, it will burn unevenly, and not provide the uniform circumferential pressure needed to cause the core of nuclear material to compress into a critical mass, even though it may be broken up and scattered.. Various safety features of a nuclear weapon. A battery which provides current, armed switch which controls the flow of current. Thermo fuses which ensure protection against fire. Various mechanical devices like safety pins and wires with seals also ensure safety of nuclear weapons and prevent untimely detonation.
