Legal Definitions - alcoholometer

An alcoholometer is a device used to measure the concentration of alcohol. In legal and practical contexts, especially when assessing individuals, this term most commonly refers to a breath alcohol testing device, widely known as a breathalyzer. These devices analyze a person's breath to estimate their blood alcohol content (BAC), which is a critical factor in determining impairment, particularly in situations involving driving, operating machinery, or other regulated activities.

• Example 1: Law Enforcement Traffic Stop
  A police officer pulls over a driver who is exhibiting erratic driving behavior. Suspecting the driver might be impaired, the officer asks them to perform a series of field sobriety tests. Following these tests, the officer uses a portable alcoholometer (breathalyzer) at the roadside. The device quickly analyzes the driver's breath sample, providing an immediate reading of their estimated blood alcohol content. This reading helps the officer determine if there is probable cause to arrest the driver for driving under the influence (DUI).

• Example 2: Workplace Safety Compliance
  A manufacturing plant has a strict policy against alcohol consumption during work hours, especially for employees operating heavy industrial equipment. After a minor safety incident involving a forklift, the plant's safety officer requires the operator to undergo an immediate alcohol test. The officer uses a certified alcoholometer to measure the operator's breath alcohol concentration. The device's reading helps the company determine if alcohol impairment played a role in the incident, ensuring compliance with safety regulations and company policy.

• Example 3: Commercial Pilot Pre-Flight Check
  Federal aviation regulations mandate that commercial pilots must not operate an aircraft with any detectable alcohol in their system. Before a scheduled flight, a pilot is randomly selected for an alcohol screening. An authorized technician administers an alcoholometer test, requiring the pilot to blow into the device. The instrument precisely measures the breath alcohol level, confirming that the pilot is free of alcohol and legally cleared to operate the aircraft, thereby ensuring passenger safety and regulatory adherence.
