The potential risk of an electric air hand dryer contributing to airborne infection in a hospital was investigated using a strain of Serratia marcescens and a strain of coagulase-negative, streptomycin-resistant Staphylococcus. Dispersal of marker bacteria by the air dryer was demonstrated within a radius of about 3 feet from the dryer and to the investigator's laboratory coat. When paper towels were used for hand drying, no dispersal of marker bacteria was demonstrated. It is suggested that air hand dryers are unsuitable for use in critical patient care areas as they may contribute to cross infection either via airborne dissemination or via contaminated personnel.
使用粘质沙雷氏菌菌株和一株凝固酶阴性、耐链霉素的葡萄球菌，研究了电动空气干手机在医院中导致空气传播感染的潜在风险。空气干手机能使指示菌在距干手机约3英尺半径范围内以及研究者的实验室工作服上扩散。当使用纸巾擦手时，未发现指示菌扩散。有人认为，空气干手机不适用于重症患者护理区域，因为它们可能通过空气传播或受污染的人员导致交叉感染。
