The SCRAM device is not infallible
The SCRAM device is a new machine that is used as a substitute for the interlock device in DWI cases in Houston and around the country. The SCRAM is much more intrusive than the interlock because it is worn at all times, and is taking alcohol readings every 30 minutes as you perspire. Also other people may see the device if it unintentionally exposed. There is a list of things that may trigger a false positive alcohol reading when using this device, like certain toiletries, perfumes and cleaning supplies. After a recent hearing in a Florida court you can also add Hairspray to the list of items that may cause a false positive when wearing the SCRAM device. Jeff Hawthorne, who is the co-founder of Alcohol Monitoring Systems Inc. and who invented the SCRAM (Secure Continuous Remote Alcohol Monitor) anklet, testified at the hearing. He said an alert could have been issued even if the defendant had not consumed alcohol. Furthermore, he stated that it is possible that hairspray could trigger an alert instead.
