For-cause
(3) For-cause. For-cause drug and alcohol tests must be conducted onsite in response to an individual's observed behavior or physical condition indicating possible substance abuse, as defined in 26.5. A for-cause drug test, alcohol test, or both, must be conducted onsite after receiving credible information either that an individual is engaging in substance abuse or in response to a portal area screening test result under paragraph (j) of this section. (4) Post-event. A post-event test for drugs and alcohol must be conducted (i) As soon as practical after an event involving a human error that was committed by an individual specified in 26.4, where the human error may have caused or contributed to the event. This test must be conducted onsite unless the individual requires offsite medical care. The licensee or other entity must test the individual(s) who committed or directed the error and need not test individuals who were affected by the event and whose actions likely did not cause or contribute to the event. The licensee or other entity must describe in its procedures what constitutes a human error. (ii) Within 4 hours of an event unless immediate medical intervention precludes the conduct of the test on the individual(s) who caused or contributed to the accident(s), if the event results in (A) An illness or personal injury to any individual which results in death, days away from work, restricted work, transfer to another job, medical treatment beyond first aid, loss of consciousness, or other significant illness or injury, as diagnosed by a licensee- or other entity-designated physician or other licensed health care professional, even if the illness or injury does not result in death, days away from work, restricted work or job transfer, medical treatment beyond first aid, or loss of consciousness; or (B) Damage to any safety- or security-related structures, systems, and components; and (5) Follow-up. An individual subject to this part who has violated the FFD policy for substance use or abuse, or the sale, use, or possession of illegal drugs must be subject to a follow-up series of tests for drugs, alcohol, or both to verify an individual's continued abstinence from substance abuse.
