W85-W99: Exposure to electric current, radiation and extreme ambient air temperature and pressure

The conditions grouped under "Exposure to electric current, radiation and extreme ambient air temperature and pressure" generally involve injuries caused by either direct or indirect exposure to these sources. An individual may receive an electric shock if they come into contact with an electrically energized object or they may experience harmful radiation if exposed to ultraviolet radiation from the sun or from other sources like X-ray machines or during radiation therapy. The impact may range from mild discomfort to severe conditions such as burns or internal damage. Conditions related to extreme temperature and pressure variations typically occur due to exposure to excessive cold or heat such as hypothermia or heat stroke, or sudden pressure changes that can result in injuries known as barotraumas. Symptoms can be varied but often involve skin lesions, changes in consciousness, pain, and internal organ dysfunction, depending on severity and type of exposure. These situations commonly demand immediate medical attention for minimization of injury and prevention of life-threatening complications.
