As a supervisor in safety-sensitive industries in Alaska — whether you’re based in Anchorage, Fairbanks, Juneau, or working in remote oilfield and trucking operations — it’s critical to understand what counts as a refusal to test under DOT regulations. A refusal to test is treated the same as a positive test result, which can lead to significant consequences for both the employee and the employer, including suspension, termination, or other regulatory penalties. Here’s a clear, employer guide to help supervisors identify what qualifies as a refusal to test.
What Qualifies as a Refusal to Test?
- Failure to show up for testing
If an employee fails to report to the designated testing location at the scheduled time, it’s considered a refusal. - Inability or failure to provide a sample
Employees must provide an adequate sample for testing. If they are unable or unwilling to do so, it counts as a refusal. - Tampering with the sample
Any attempt to alter, dilute, or substitute the sample is considered tampering and is treated as a refusal. - Refusal to sign the testing forms
Employees must sign the necessary forms to authorize the test. Refusing to sign these forms constitutes a refusal to test. - Leaving the testing site before completion
If an employee leaves the testing site before the test is complete, this is treated as a refusal. - Failure to cooperate with the testing process
Non-cooperation, such as not following instructions or being disruptive during the testing process, can also be classified as a refusal.
Supervisors must understand the implications of a refusal because it is treated as a positive test result under DOT regulations. They should be vigilant, document any incidents that may qualify as a refusal, and maintain clear communication with the company’s Medical Review Officer (MRO) to ensure compliance. Failure to follow refusal procedures can lead to regulatory violations that affect legal standing and workplace safety, so proactive supervisor training on refusal scenarios is essential.
