A subject-matter of the present invention is a safety igniter for a pyrotechnic munition component capable of being subjected to slow cook-off comprising a structure in the form of a casing and a solid pyrotechnic charge present in the structure. This safety igniter, which is composed solely of a block of solid pyrotechnic composition based on pentrite, is intended to bring about the combustion without detonation of the pyrotechnic charge when the munition component is subjected to slow cook-off.
