Our breath alcohol testing provides the DOT and employers the information they need about alcohol abuse within their organization.
Breath Alchohol Testing
Department of Transportation regulations only permit breath or saliva alcohol testing. The Department of Transportation has several reasons why they prefer breath alcohol versus blood.
- Non-Invasive procedure
- Simple participation from the subject
- Immediate results
- Relatively inexpensive
- Portability of equipment allows flexibility in where to perform procedure
- Reduces lost time for employers
Henry's Law is the scientific principle upon which breath alcohol testing is based. Henry's Law states
"At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid."
When a good deep lung sample is analyzed, the three digit alcohol concentration reading should not differ by more than -5% from a blood sample drawn at the same time. Thus making breath alcohol testing extremely accurate.
All National Highway Traffic Safety Administration (NHTSA) approved devices must be capable of detecting alcohol at levels of 0.020 or less and not register acetone to cause a false positive.
