In addition, site conditions may permit the use of cooling devices such as cool water hose, ice packs, cool towels, etc. Victims caught in a fire have inhaled toxic smoke from furnishings and plastics that have released cyanide in the burning process. Following a nuclear detonation, some of the casualties with survivable injuries are possibly contaminated with radiological material. For each CBRN message type, there are three set identifiers - (M) mandatory, (C) conditional and (O). Remove inner clothing. In addition, use of ultraviolet light can increase the risk of skin cancer and eye damage; therefore, a qualified health professional should assess the benefits and risks associated with ultraviolet light prior to its use at a waste site.
