RESUMO
The explosive act Canada has jurisdiction over explosives storage and manufacturing sites (except storage at mines) in Canada. The siting of storage and manufacturing facilities takes into consideration a number of factors, with one the most important being Quantity - Distance (Q-D). The Q-D principles adopted by Canada are based on those published by the North Atlantic Treaty Organization (NATO) which were derived from various sources of data such as accidents and trials. Eplosives are classified, usually by testing or analogy, into Hazard Divisions (HD). Q-D tables are based on hazards division and assume that an explosion will occur sometime during the life on the site. Other storage or manufacturing sites or places external to the potential donor site must be taken into consideration when determining how much explosive may be present (quantity) or how far away the site must be (distance) (AU)
