This photograph of two common types of detonators is published at the request of CIB chief, Det. -Supt. Calman so that parents and children will be able to identify these small but deadly explosives. on the left is an electric detonator, complete with wire attached, while alongside is an aluminium detonator for "crimping" on to fuse. Both are "lethal" and will explode if dropped or knocked. Many have found their way into the hands of children recently, and several boys have been maimed. July 25, 1955.
