Screening Test Technicians and Breath Alcohol Technicians

Screening test technicians (STTs) and breath alcohol technicians (BATs) are professionals trained to conduct alcohol screening tests and confirmation tests, respectively, and transmit the results to the employer in a timely and confidential manner. Alcohol screening tests can be either a breath or saliva test, with the STT documenting the test result on an Alcohol Test Form (ATF). Alcohol confirmation tests (i.e., the second test given to an employee whose screening test result is 0.02 or above) are conducted by collecting and analyzing breath specimens using an approved evidential breath testing device and documenting the test result on a DOT ATF. Regulations concerning STTs, BATs, and the alcohol test collection process are found in 49 CFR Part 40 Subparts J-M.
