Dangerous cargoes include substances, materials, production, waste products, which may cause damage to the environment due to their nature and specificity. This damage may occur in case of any negative factor in the process of transportation, handling or storage. They may cause explosion, fire or damage to vehicles, equipment, buildings and structures, as well as death, injury, poisoning, burns or disease in humans, animals and birds. An emergency card may be issued for such cargoes on a carrier’s demand. The card contains forwarding freight characteristics (safety class) and rules of conduct in emergency conditions.
