"Calcium hypochlorite, 70% available chlorine" is the commercial description of a substance used for purifying water supplies and, in particular, swimming pools. It is sometimes referred to in shipping documents as "bleaching powder". This is a misnomer and can be misleading because the hazardous properties of the two substances are quite different. It is of interest because it has been responsible for a number of fires and explosions in ships. During the last few years there have been some twelve major incidents in ships and many incidents on land about which there are little data. Describes the nature of the incidents, possible couses of fire such as spontaneous ignition by self-heating or contamination and should not be treated as a simple Oxidiying agent. Reviews current research programs interim recommendation and suggested future action with regard to modifying existing IMCO and national codes for carriage of this material.
