A New York man was convicted in a Virginia court on Friday on charges of drunken driving. At the time of his arrest, police reported a blood-alcohol level of 0.15.
The man's defense attorney claimed his client used a hand sanitizer several times on the day he was arrested and that the ethanol in the hand sanitizer affected his blood-alcohol level that night.
Can hand sanitizer applied to the skin really affect a breath alcohol test?
Probably not. According to a study among Australian health care workers.
According to slate.com, twenty workers applied Avangard—a hand sanitizer with 70 percent ethanol (compared with Purell's 62 percent—30 times during one hour, mimicking the usage in intensive-care units.
One to two minutes after the final exposure, six of the workers did show a slight bump in breath-ethanol levels—between 0.001 percent and 0.0025 percent, about the same effect as one-tenth of a beer on an average-size male.
Ten to 13 minutes after the final application, however, all the health care workers' breath-ethanol levels had returned to zero. In Fossella's case, a period of several hours separated his Purell usage and his breathalyzer test: He claimed to have used the hand sanitizer during the afternoon of April 30 and wasn't pulled over until just after midnight.
