T51-T65: Toxic effects of substances chiefly nonmedicinal as to source

T59: Toxic effect of other gases, fumes and vapours

The conditions within the T59 group are associated with the harmful impact of inhaling various gases, fumes, and vapours not classified elsewhere. These harmful substances could be inhaled in several circumstances such as workplace exposure, household accidents, or intentional misuse. Exposure to these toxic substances can affect multiple organ systems, most commonly the respiratory system. Typical symptoms might include coughing, shortness of breath, chest pain, nausea, or dizziness. The progression of these conditions can vary significantly, with some individuals recovering fully after exposure ends, while others may have long-term health issues. In severe cases, high levels of exposure can lead to life-threatening conditions like chemical pneumonia or pulmonary edema. The intensity of symptoms can be influenced by the type and concentration of the substance, duration of exposure, and individual health factors.
