DOT Breath Alcohol Testing in Florence

DOT Alcohol Testing Scenarios We Cover

Federal regulations under 49 CFR Part 40 require DOT-covered employers to conduct breath alcohol testing across six distinct situations. Fastest Labs of Florence administers all of them.

• Pre-employment: Required before a covered employee begins performing safety-sensitive functions
• Random selection: Drawn from a scientifically valid random pool at rates set annually by each DOT agency
• Post-accident: Must be completed within federally specified timeframes after a qualifying accident; delays can affect DOT compliance determinations
• Reasonable suspicion: Triggered when a trained supervisor observes specific signs of impairment
• Return-to-duty: Conducted after a substance abuse professional (SAP) evaluation before an employee resumes safety-sensitive duties
• Follow-up: Ongoing unannounced testing following a return-to-duty determination

Under 49 CFR Part 40, breath is the only DOT-permitted method for alcohol confirmation testing, and only saliva or breath are permitted for screening. Urine alcohol tests don’t qualify for DOT compliance. Our 24/7 availability means post-accident situations don’t have to leave you without a provider, regardless of when an incident occurs.

What to Expect During a DOT Breath Alcohol Test

The process is straightforward. A DOT breath alcohol test involves two steps: a screening test, and if the initial result is 0.02 BAC or above, a confirmation test using an evidential breath testing device. Our certified breath alcohol technicians follow DOT-required observation and documentation procedures throughout to preserve chain of custody. We use the Lifeloc Phoenix 6.0 with individually-wrapped mouth blow tubes and provide the three-part breath alcohol testing form on-site. Results are available as soon as 24-48 hours.

Under DOT rules, a BAC of 0.04 or above constitutes a violation for safety-sensitive employees and requires immediate removal from duty. A result between 0.02 and 0.039 triggers a temporary removal from safety-sensitive functions without constituting a formal violation. The employee receives a copy of results on-site; the DER receives their copy through standard reporting. Whether you’re an employer scheduling tests for your workforce or an individual reporting for a required test, we make the process clear from start to finish.
