Breath and Alcohol Testing

Comprehensive alcohol testing solutions for workplace safety and DOT compliance

Breath and Alcohol Testing Explained

At Sky Drug Testing, we provide comprehensive breath and alcohol testing services to help you maintain safety standards and comply with DOT regulations. Alcohol testing is a critical component of any comprehensive drug and alcohol testing program, ensuring that safety-sensitive employees are not under the influence while performing their duties.

Breath alcohol testing is conducted using evidential breath testing devices (EBTs) that provide immediate, accurate results. This type of testing is required for DOT-regulated employees and is also commonly used in workplace safety programs to detect recent alcohol consumption.

Under FMCSA and DOT regulations, alcohol testing must be conducted by trained Breath Alcohol Technicians (BATs) using approved evidential breath testing devices. All procedures are found in the Department of Transportation's (DOT) rule, 49 CFR Part 40.

What is Breath Alcohol Testing?

Breath alcohol testing measures the concentration of alcohol in a person's breath, which correlates to their blood alcohol concentration (BAC). This non-invasive method provides immediate results and is the preferred method for workplace alcohol testing due to its accuracy, convenience, and immediate availability of results.

The test must be conducted using DOT-approved evidential breath testing devices by certified Breath Alcohol Technicians to ensure accurate and legally defensible results.

Breath Alcohol Testing Requirements

  • Certified BAT: Testing must be conducted by a trained and certified Breath Alcohol Technician (BAT).
  • Approved EBT Device: Must use DOT-approved evidential breath testing devices that meet federal standards.
  • Immediate Testing: Alcohol testing should occur as soon as possible after reasonable suspicion or other triggering events.
  • Proper Documentation: All test results must be properly documented and maintained for audit purposes.
  • Chain of Custody: Strict chain of custody procedures must be followed to ensure test integrity.

Testing Scenarios

Breath alcohol testing is required in the following situations:

  • Pre-employment testing
  • Random testing
  • Post-accident testing
  • Reasonable suspicion testing
  • Return-to-duty testing

Frequently Asked Questions All FAQs

Breath alcohol testing measures the concentration of alcohol in a person's breath using evidential breath testing devices. It's required for DOT-regulated employees in pre-employment, random, post-accident, reasonable suspicion, return-to-duty, and follow-up testing scenarios.

Only trained and certified Breath Alcohol Technicians (BATs) can conduct breath alcohol testing. These technicians must be properly trained and certified to use evidential breath testing devices and follow DOT procedures.

DOT-approved evidential breath testing devices (EBTs) are used for breath alcohol testing. These devices must meet federal standards and be properly calibrated and maintained to ensure accurate results.

The legal limit for alcohol in DOT testing is 0.04 blood alcohol concentration (BAC). Any result at or above this level is considered a positive test and requires immediate removal from safety-sensitive duties.

DOT-approved evidential breath testing devices are highly accurate when properly calibrated and operated by certified technicians. These devices provide immediate, reliable results that are legally defensible in court proceedings.

If an employee tests positive for alcohol (0.04 BAC or higher), they must be immediately removed from safety-sensitive duties and cannot return until completing the return-to-duty process, including evaluation by a Substance Abuse Professional (SAP).

Refusing a breath alcohol test is treated the same as a positive test result. Employees who refuse testing must be immediately removed from safety-sensitive duties and cannot return until completing the return-to-duty process.

Breath alcohol testing devices must be calibrated according to manufacturer specifications and DOT requirements. This typically includes daily calibration checks and periodic maintenance by qualified technicians to ensure accuracy.

All breath alcohol tests must be properly documented, including test results, device calibration records, technician certification, and chain of custody documentation. These records must be maintained for audit purposes and DOT compliance.

Breath alcohol testing can be conducted at various locations, but the testing environment must be appropriate and the device must be properly calibrated. Mobile testing services are available for convenience while maintaining all required procedures and documentation.
