(a) If an employee is unable to provide sufficient breath to complete a test on a non-evidential breath testing device, the procedures of § 40.69 apply.

(b) If an employee is unable to provide sufficient saliva to complete a test on a saliva screening device (e.g., the employee does not provide sufficient saliva to activate the device), the STT, as provided in § 40.101 of this part, shall conduct a new test using a new device. If the employee refuses to complete the new test, the STT shall terminate testing and immediately inform the employer. This constitutes a refusal to test.

(c) If the new test is completed, but there is an insufficient amount of saliva to activate the device, STT shall immediately inform the employer, which shall immediately cause an alcohol test to be administered to the employee using an EBT.
