Arrangement for blocking the operation by an operator of a vehicle or a machine

摘要

The invention is directed to an arrangement for blocking the operation by an intoxicated operator of a machine or a motor vehicle. The arrangement has a measuring apparatus which determines the blood alcohol content of the operator and an evaluation unit connected to the machine or motor vehicle. The evaluation unit receives measurement data supplied by the measurement apparatus and enables the machine or motor vehicle when the measurement data satisfies at least one predetermined condition. The arrangement is improved in that the sobriety of the operator is recognized before the starting operation of the machine or motor vehicle without it being necessary to supply a breath sample. The measuring apparatus includes a gas sensor which is a sensor for measuring the blood alcohol content via permeation through the skin of the operator. The measuring apparatus is configured so that it can be worn by the operator preferably on the leg or arm.
