Abstract

The present invention relates to a tricresyl phosphate-free oil which can be used as lubricant or hydraulic oil. The oil is distinguished by extremely low human toxicity. In particular, the oil is suitable as turbine oil, i.e. as lubricant oil in aircraft turbines, with which, in the case of a fume event, symptoms of the aerotoxic syndrome in aircraft passengers can be prevented. In addition, the present invention relates to the corresponding use of the turbine oil according to the invention for the prophylaxis of the aerotoxic syndrome in the case of a fume event. In addition, the invention describes a turbine which contains a corresponding turbine oil as lubricant. Furthermore, the method for operating a turbine is indicated.
