Breath Alcohol Testing

Breath alcohol testing devices measure how much alcohol is currently in the blood.  The legal limit for being considered impaired by alcohol while driving is .08.  However, the Department of Transportation guidelines mandates that a .04 positive alcohol test requires removal of an employee from driving or other safety-sensitive tasks.  A .02 result, under DOT regulations, can require removal from tasks for a certain period of time.


Mandatory alcohol and drug testing are required by the United States Department

of Transportation for some occupations and industries.  


This mandatory testing includes trucking, aviation, maritime, pipeline, railroad,

and transit employees in safety-sensitive occupations.   


Employers outside the mandate of DOT testing typically use alcohol testing under specific circumstances:

  • The employer may have a policy that tests when there is reasonable suspicion also known as probable-cause testing, and there are documented signs of possible alcohol or drug use by an employee.

  • Post-accident testing occurs when there is suspected alcohol or drug use that caused a property damage or personal injury accident in the workplace.

  • Random testing may be performed on an unannounced, unscheduled basis on employees who have been selected arbitrarily from a testing pool.

BODT breath alcohol technicians (BAT) only use Evidential Breath Testing (EBT) devices approved by the Department of Transportation.  


Our EBT devices provide the following capabilities:

  1. Printed triplicate result

  2. Assigns a unique number to each completed test

  3. Prints, on each copy of the result, the manufacturer's name for the device, its serial number, and the time of the test

  4. Distinguishes alcohol from acetone at the 0.02 alcohol concentration level

  5. Tests an air blank; and

  6. Performs an external calibration check
