Which below does not constitute potentially disqualifying information (PDI)?

• A. Suicide attempt or threat
• B. Alcohol and/or drug-related incidents
• C. Use of alcohol in an individual that does not have a diagnosis of alcohol dependence
• D. Subsequent use of alcohol in an individual returned to duty with the diagnosis of alcohol dependence

Answer: (C)

PDI refers to information that signals a risk to safety, reliability, or medical fitness for duty. Among the examples, a suicide attempt or threat and alcohol- or drug-related incidents clearly indicate significant safety and health risks, and returning to duty with a diagnosed alcohol dependence followed by continued alcohol use shows a relapse and ongoing impairment. These are the kinds of indicators that can disqualify someone because they directly affect readiness and safety.

Using alcohol without a diagnosis of dependence does not automatically constitute disqualifying information. It may represent normal or controlled use without impairment, so it does not by itself indicate a disqualifying risk.
