Abstract

An apparatus and method are disclosed for detecting the presence of a substance, such as an alcohol, on the hand of an operator of the apparatus. The apparatus may, for example, be a door handle. The apparatus comprises a fuel cell arranged to consume said substance in order to generate a signal indicative of the presence of that substance. If the substance is a bactericide, the system and method can be used to determine whether or not an operator's hand has been cleaned in a prescribed manner.
