An electrically primable igniter charge yield has a composition that yields a reduced proportion of toxic vapors after the deflagration. The composition of the charges contains, as the oxidizing agent, zinc peroxide and, as a component providing additional energy, initiating explosives of the kind which do not trigger a detonation in direct contact with press-molded elements of nitrocellulose propellant charge powders. Among these initiating exposives are the potassium salts of trinitrophenol or trinitroresorcinol. The components of the igniter charges are mixed with fibers of an electrically conductive material. Suitable conductive materials are carbon or metals, such as iron or copper, or metal alloys, such as brass, for example. The igniter charges furthermore contain a binder which is preferably a secondary explosive, such as, for example, nitrocellulose.
