<p>A shock tube initiator comprises a plastics tubing having an unobstructed axial bore, said tubing having throughout its length an inner surface upon which unconsolidated reactive materials are provided as a loosely adherent dusting of shock-dislodgeable particles at a core loading sufficiently low to avoid rupture of the tubing in use, wherein said reactive materials comprise fuel particles selected from the group consisting of metals, quasi-metals and non-metallic fuels, and, as oxidant, at least about 20% (by weight) of ammonium perchlorate, preferably up to about 99% (by weight) ammonium perchlorate. <IMAGE></p> |
