Definition - What does Screening Test Technician mean?
A screening test technician (STT) is a person who is qualified by the Department of Transportation (DOT) to administer the alcohol screening test to employees who fall under DOT regulations. The STT also instructs and assists them in the process. The STT explains the test methodology and answers any questions people may have regarding the test, and is authorized to use an approved screening device (ASD). The major distinction between a STT and a breath alcohol technician is that a STT is not trained on how to perform calibration of a breath alcohol device and is not certified to perform a confirmation alcohol test.
SureHire explains Screening Test Technician
A screening test technician (STT) uses an approved screening device (ASD) to conduct alcohol testing under DOT regulations. They also explain the testing procedures to the employees being tested and assist them when necessary. A STT is required under DOT Part 40 regulations and helps to ensure the process follows the regulations properly. However, STTs can conduct non-DOT alcohol screening testing as well, should an employer chose to use them. In this case it is vitally important the STTs do not use DOT or ATF forms for non-DOT and non-ATF testing.
The screening test technician must meet required qualifications and have passed certification testing. Training must comply with the Department of Transportation Model STT course. Anyone certified as a breath alcohol technician (BAT) may serve as an STT but a STT needs additional training before being allowed and certified to serve as a BAT.
A screening test technician is responsible for keeping the integrity of the entire alcohol testing process under DOT guidelines, and must ensure the privacy of those employees or applicants being tested while avoiding statements or behavior that might be considered inappropriate or offensive.
STTs can not conduct confirmation tests. STTs are only certified to conduct screening testing with an ASD, while BATs are further trained for use of an ASD or evidential breath testing device (EBT) and the confirmation testing. If a screening test conducted by an STT returns a positive result during DOT testing, a confirmatory test by a BAT must be completed no sooner that 15 minutes but within 30 minutes according to DOT guidelines.
