Non-DOT Breath Alcohol — Introduction
Non-DOT breath alcohol testing is the workplace alcohol-testing method used outside the DOT-regulated transportation sector — post-incident, reasonable suspicion, pre-employment, return-to-work. Same EBT technology as DOT BAT, different rule set. This module covers operation, procedure, documentation, and how to keep results defensible.
What This Module Covers
- The non-DOT alcohol testing program
- EBT operation, calibration, and QC
- Screening and confirmation procedures
- The 15-minute observation period
- Refusals, invalid tests, mouth alcohol
- Documentation that holds up in a dispute
Who This Is For
HR generalists, safety managers, clinic staff, and existing DOT BATs who also perform non-DOT testing. The technique is the same — only the rule book changes.
DOT BAT vs. Non-DOT Alcohol Testing
| Element | DOT BAT (Part 40) | Non-DOT |
|---|---|---|
| Regulation | 49 CFR Part 40 | None (employer policy) |
| Tester qualification | §40.213 (7 mocks) | Voluntary / device IFU |
| Form | Federal ATF | Non-DOT (varies) |
| Device | NHTSA CPL only | NHTSA CPL strongly preferred |
| Screening threshold | 0.02 (defined) | Per employer policy |
| Violation threshold | 0.04 | Per employer policy |
| Confirmation interval | 15–30 min | Recommended same |
| Mouth alcohol protections | 15-min wait required | Recommended same |
Regulatory Context
Non-DOT alcohol testing has no federal Part 40 equivalent. The framework is employer policy + state law + OSHA general-duty considerations. Most defensible programs voluntarily follow DOT BAT procedure.
The Legal Framework
- Employer written policy — sets thresholds, consequences, RS triggers
- State workplace drug-free programs — many states give insurance discounts for compliant programs (FL, GA, OH, others)
- OSHA — post-incident testing must not deter injury reporting (2016 rule clarification)
- State employment law — some states limit RS testing or require specific evidence of impairment
OSHA Post-Incident Testing Note
OSHA's 2016 anti-retaliation rule made clear that blanket post-incident drug/alcohol testing can be unlawful if it would deter employees from reporting injuries. Programs that test only when there's a reasonable possibility drug/alcohol use contributed to the incident are safer.
State Marijuana Laws
Several states (NY, NJ, CT, CA, WA, others) restrict adverse employment action for off-duty marijuana use. Alcohol is separate — but a non-DOT program testing for both should review state law for the drug side.
The Tester
The non-DOT alcohol tester is anyone trained on the EBT being used. There's no federal "BAT" credential for non-DOT — but documented training on the specific device is essential for defensibility.
What a Non-DOT Tester Does
- Verifies donor identity
- Conducts the 15-minute observation
- Operates the EBT per IFU
- Reads and records the result
- Conducts confirmation test when triggered
- Completes the non-DOT alcohol testing form
- Notifies the DER on policy-violation results
Training Recommendation
- Vendor / manufacturer training on the specific EBT model
- 5+ supervised mock tests (mix of negative, positive, refusal)
- Annual refresher
- Document everything — training, calibration, every test
The Testing Site
The non-DOT alcohol testing site has the same privacy + observation requirements as DOT. The 15-minute deprivation period in particular needs an environment you can supervise.
Site Requirements
- 1Privacy — test cannot be overseen or overheard by others
- 2Stable temperature (EBTs are temperature-sensitive)
- 3Power for the EBT
- 4Clean work surface for EBT + form
- 5No food, drink, mints, gum, vape within reach of donor
Security During Test
- Donor continuously observed during 15-minute wait
- EBT and supplies under tester's physical control
- Result printed / recorded immediately
- Form visible to donor at signing
The EBT & Supplies
The EBT (Evidential Breath Testing device) is the centerpiece. NHTSA-Conforming Products List devices are preferred even for non-DOT use because of their evidentiary defensibility.
The EBT
- aNHTSA CPL — strongly preferred for evidentiary defensibility
- bFuel cell technology beats semiconductor for accuracy and specificity
- cCalibration current per manufacturer interval
- dQAP records on file
Supplies
- EBT — calibrated, in service
- Disposable mouthpieces — fresh sealed mouthpiece for every blow
- Non-DOT alcohol testing form
- Device IFU — printed at site
Calibration
Verify per manufacturer schedule (typically monthly or by event count). Log every calibration. An EBT used outside calibration interval = legally indefensible result.
The Non-DOT Alcohol Testing Form
Non-DOT alcohol testing forms vary by employer. Most mirror the DOT ATF — donor info, screening result, optional confirmation, signatures.
Form Components
Most non-DOT alcohol forms mirror the DOT ATF:
- Donor name, SSN/ID, DOB
- Employer name + DER contact
- Reason for test
- Donor affirmation + signature
- Screening result: device serial, calibration date, time, result
- Confirmation result (if triggered): same fields
- Tester signature + printed name
- Donor signature on result acknowledgment
Copy Distribution
| Copy | Goes To |
|---|---|
| 1 | Site / file (retain per policy) |
| 2 | Employer / DER |
| 3 | Donor |
Employer Information
For non-DOT alcohol testing, the employer or program provides donor info, reason for test, and routing. Confirm everything BEFORE the donor walks in.
Required from Employer
- Donor name + ID
- Employer name + DER contact
- Reason for test (post-incident, RS, pre-employment, RTW)
- Screening + violation thresholds (employer-set; common: 0.02 / 0.04)
- Notification protocol for policy-violation results
Donor ID & the 15-Minute Wait
Donor identity verification is standard photo ID. The 15-minute observation period is the most important procedural element — no mouth alcohol contamination.
Acceptable ID
Government photo ID, employer photo badge, or in-person ID by employer representative.
⏱️ The 15-Minute Wait
Critical for mouth alcohol elimination. During the 15-minute observation:
- ! No eating or drinking
- ! No smoking or vaping
- ! No regurgitation or belching into the mouth
- ! No mints, gum, dental product, mouthwash
Why It Matters
Recent oral alcohol (mouthwash, recent drink) can drive a screening reading above policy threshold. The 15-minute wait clears mouth alcohol so the reading reflects breath alcohol from the bloodstream — what you actually want to measure.
Screening & Confirmation
The non-DOT alcohol test follows the same two-step pattern as DOT: screening (always), then confirmation (if screening ≥ a threshold). The threshold value is set by employer policy — many use 0.02 or 0.04 like DOT.
Screening Procedure
Greet & Verify ID
Explain procedure.
Donor Reads + Signs Affirmation
15-Minute Wait
Under observation. Nothing in mouth. Nothing consumed.
Power Up EBT
Self-test. Verify ready.
Open Fresh Mouthpiece
In donor view.
Donor Blows
One continuous breath until device signals stop.
Record Result
Show donor the reading.
Decide Next Step
Below screening threshold → done. At or above → confirmation.
Confirmation Procedure
Wait 15–30 Minutes
Continue observation.
Air Blank or Different EBT
Per device IFU.
Fresh Mouthpiece
New sealed mouthpiece in donor view.
Confirmation Blow
Record Result
This is the test of record. The screening reading is preliminary.
Donor Signs Result
Notify DER
Per policy — immediately for at-or-above-violation results.
When Things Go Sideways
Same disruptors as DOT BAT: mouth alcohol, refusal, invalid test, insufficient breath. Response driven by employer policy.
Mouth Alcohol
If the screening reading is high but the confirmation reading is markedly lower, mouth alcohol is the explanation. The confirmation governs. Document both.
Refusal Triggers
- ! Refuses to take the test
- ! Refuses to provide adequate breath sample (no medical reason)
- ! Leaves before complete
- ! Refuses to sign result acknowledgment
- ! Engages in conduct that obstructs the test
Insufficient Breath
Coach Technique
Encourage continuous, full exhalation.
Retry
Document attempts.
If Unable
Stop, document, notify DER. Employer arranges medical evaluation if needed.
Invalid Test
- ! Device error during the blow
- ! Air blank failure
- Discard, document, repeat from screening
- Two invalids in a row → device out of service, alternate device
Training & Documentation
Non-DOT alcohol testers don't have a federal qualification standard — but EBT calibration, documented training, and QC logs are essential.

Best Practices
Most non-DOT alcohol testing problems come from the same place as DOT BAT: rushing the 15-minute wait, missing calibration, mishandling mouth alcohol. Build a checklist.
Top 10 Non-DOT Alcohol Testing Mistakes
- 1Skipping the 15-minute wait (donor "looks fine")
- 2Reusing a mouthpiece
- 3Recording the screening result as the test of record
- 4Missing EBT calibration
- 5Letting donor handle the mouthpiece out of view
- 6No air blank between screening and confirmation
- 7Not notifying the DER on policy-violation result
- 8Treating "I can't blow" as automatic refusal without protocol
- 9Filling in confirmation when screening was below threshold
- 10No documentation of an invalid test
Best Practices Checklist
- Calibrate + verify before each shift
- Eyes on donor through 15-minute wait
- Fresh mouthpiece every blow, in donor view
- Air blank for confirmation
- Confirmation governs over screening
- DER notified for policy-violation results
- When in doubt, follow DOT BAT procedure — sets the defensibility ceiling high
