Subpart L—Alcohol Screening Tests

§ 40.243 What is the procedure for an alcohol screening test using an EBT or non-evidential breath ASD?
 
As the BAT or STT, you must take the following steps:
 
(a) Select, or allow the employee to select, an individually wrapped or sealed mouthpiece from the testing materials.
 
(b) Open the individually wrapped or sealed mouthpiece in view of the employee and insert it into the device in accordance with the manufacturer's instructions.
 
(c) Instruct the employee to blow steadily and forcefully into the mouthpiece for at least six seconds or until the device indicates that an adequate amount of breath has been obtained.
 
(d) Show the employee the displayed test result.
 
(e) If the device is one that prints the test number, testing device name and serial number, time, and result directly onto the ATF, you must check to ensure that the information has been printed correctly onto the ATF.
 
(f) If the device is one that prints the test number, testing device name and serial number, time and result, but on a separate printout rather than directly onto the ATF, you must affix the printout of the information to the designated space on the ATF with tamper-evident tape or use a self-adhesive label that is tamper-evident.
 
(g) If the device is one that does not print the test number, testing device name and serial number, time, and result, or it is a device not being used with a printer, you must record this information in Step 3 of the ATF.
