In a method for preventing the occurrence of an explosive state in a gas mixture, especially of solvents in air, in an essentially confined space, virtually complete oxidation of at least part of the gas mixture taking place, either the temperature difference DELTA T between the temperatures of the gas mixture before and after the oxidation is determined, and if the temperature difference DELTA T is greater than a maximal permissible temperature increase DELTA Tmax, safety measures are taken, or the temperature T1 of the gas mixture before the oxidation and the temperature T2 of the gas mixture after the oxidation are measured, and the measured temperatures T1 and T2 are compared with a minimum temperature Tmin before oxidation of the gas mixture and a maximum temperature Tmax after oxidation of the gas mixture, the difference between Tmax and Tmin being less than, or equal to, the maximal permissible temperature increase DELTA Tmax, and if the measured temperatures T1 and T2 are outside the interval determined by the maximum and minimum temperatures Tmax and Tmin, safety measures are taken. In addition, the use of this method in drying webs printed with ink, and an appliance for this purpose are described.
