49 CFR 1546.411 - Continuing qualifications of screening personnel.
(a) Impairment. No individual may perform a screening function if he or she shows evidence of impairment, such as impairment due to illegal drugs, sleep deprivation, medication, or alcohol.
(b) Training not complete. An individual who has not completed the training required by § 1546.405 may be deployed during the on-the-job portion of training to perform security functions provided that the individual -
(1) Is closely supervised; and
(2) Does not make independent judgments as to whether individuals or property may enter a sterile area or aircraft without further inspection.
