T59: Toxic effect of other gases, fumes and vapours

T59.1: Toxic effect: Sulfur dioxide

Sulfur dioxide is an irritant gas that is produced, among other things, when burning coal or oil.

Irritant gases can irritate the mucous membranes. If the mucous membranes in the eyes and nose become irritated, you can burn your eyes, have an increased flow of tears or a runny nose. If the mucous membranes in the respiratory airways are irritated, you can have shortness of breath and cough, for example. Water can accumulate in the lungs. The respiratory airways can also become inflamed. This may result in restricted breathing and the circulation failing. In some cases, there is also permanent damage to the lungs.
