TOXICOLOGICAL INFORMATIONInformation on toxicological effectsRisks at inhalation:Risks at contact:Propane/butane is a gas slightly narcotic and may in highly concentrated form irritatemucous membranes and cause suffocation. The suffocation effect is proportional to thedecrease of the partial pressure of the oxygen in the inhalation air obtained at a mixtureof propane/butane and air. When the oxygen content has decreased to three fourths orless of the normal content asphyxia occurs. The body interprets this as a lack of oxygenand reacts (at concentrations of 50 vol.-% propane/butane in air) with pronouncedsymptoms of suffocation in the form of difficulty to breath and hyperventilationsimultaneously with deteriorated reaction ability and impaired muscle co-ordination. Moreserious cases (at concentrations of 75 vol.-% propane/butane in air) may end inunconsciousness and death.Propane/butane in liquefied or gaseous form may cause serious frostbites on skin oreyes. If propane/butane in liquefied form gets into contact with objects of a highertemperature than the liquid itself it results in fierce boiling and splashing.Page 3 of 4 Print date: 16/11/2012
