Explosives and firework items shall undergo hazard classification prior to any transport. The hazard category denotes the wideness and art of the hazard caused by the explosive or firework item in case of accident. The hazard classification of explosives or items containing explosives shall be carried out from the viewpoint of transportation, i.e. considering the intended transport packages of the products.
As for unpacked firework items, there is the alternative to assign the hazard classification on the basis of product type, pyrotechnical substance content and item dimensions.
The determined hazard category is also used to define the safety measures required, such as the necessary safety distances during manufacture and in storage.
