This study was undertaken to determine if the application of alcohol-based hand sanitizers (ABHSs) to the hands of a breath test operator will affect the results obtained on evidential breath alcohol instruments (EBTs). This study obtained breath samples on three different EBTs immediately after application of either gel or foam ABHS to the operator's hands. A small, but significant, number of initial analyses (13 of 130, 10%) resulted in positive breath alcohol concentrations, while 41 samples (31.5%) resulted in a status code. These status codes were caused by ethanol vapors either in the room air or their inhalation by the subject, thereby causing a mouth alcohol effect. Replicate subject samples did not yield any consecutive positive numeric results. As ABHS application can cause a transitory mouth alcohol effect via inhalation of ABHS vapors, EBT operators should forego the use of ABHS in the 15 min preceding subject testing.
本研究旨在确定向呼气测试操作人员的手部涂抹酒精基洗手液（ABHSs）是否会影响在呼气酒精证据测试仪（EBTs）上获得的结果。本研究在操作人员手部涂抹凝胶或泡沫状ABHS后，立即在三种不同的EBT上采集呼气样本。少量但显著的初始分析（130次中有13次，10%）得出呼气酒精浓度为阳性，而41个样本（31.5%）得出状态码。这些状态码是由室内空气中的乙醇蒸气或受试者吸入乙醇蒸气引起的，从而导致口腔酒精效应。重复的受试者样本未产生任何连续的阳性数值结果。由于涂抹ABHS可通过吸入ABHS蒸气导致短暂的口腔酒精效应，EBT操作人员应在对受试者进行测试前15分钟内避免使用ABHS。
