FMCSA

Any accident involving a fatality requires testing.

Testing is also required in accidents in which one or more motor vehicles are towed from the scene or in which someone is treated medically away from the scene; and a citation is issued to the CMV driver.

PHMSA

An accident is one involving gas pipeline facilities or LNG facilities or involving hazardous liquid or carbon dioxide pipeline facilities.

FAA

Accident means an occurrence associated with the operation of an aircraft which takes place between the time any person boards the aircraft with  the intention of flight and all such persons have disembarked, and in which any person suffers death or serious injury, or in which the aircraft receives substantial damage. Testing must occur if employee’s performance either contributed to the accident or cannot be completely discounted as a contributing factor of the accident. The decision not to test an employee must be based on a determination, using the best information available at the time of the determination, that the employee’s performance could not have contributed to the accident./ Monetary damage is not a factor in determining what constitutes an “accident.”

FRA

FRA’s post-accident testing rule requires urine and blood specimen collection from surviving employees and also tissue from deceased employees (these collection procedures go well beyond the normal Part 40 procedures). For surviving employees, these specimens are collected at an independent medical facility. FRA regulation, 49 CFR Part 219 Subpart C, stipulates the level of events requiring testing and who has to be tested. The collected specimens are analyzed only at FRA’s contract laboratory. Post-accident testing provides FRA with accident investigation and usage data.

FTA

Any accident involving a fatality requires testing. Testing following a non-fatal accident is discretionary: If the employer can show the employee’s performance could not have contributed to the accident, no test is needed. Non-fatal accidents that may require testing must have disabling damage to any vehicle or immediate medical attention away from the scene to meet the testing threshold.

USCG

Definition of incident requiring testing: An SMI is defined in 46 CFR 4.03-2. In general, an SMI is: A discharge of 10,000 gallons or more of oil into the navigable waters of the United States, whether or not resulting from a marine casualty; a discharge of a reportable quantity of a hazardous substance into the navigable waters or into the environment of the United States, whether or not resulting from a marine casualty; or a marine casualty or accident required to be reported to the Coast Guard, involving a vessel in commercial service, and resulting in any of the following: One or more deaths; an injury to any person (including passengers) which requires professional medical treatment beyond first aid, and, in the case of a person employed on board a commercial vessel, which renders the person unable to perform routine vessel duties; damage to property in excess of $100,000; actual or constructive total loss of any inspected vessel; or actual or constructive total loss of any uninspected, self-propelled vessel of 100 gross tons or more.
