Post-Accident Testing Definition 

PHMSA regulations in Part 199 require pipeline operators and operators of Liquefied Natural Gas (LNG) facilities to conduct post- accident drug and alcohol tests of covered employees. Within the mandated timelines after a reportable pipeline accident or incident, operators must drug and alcohol test each covered employee whose:

  • Performance either contributed to the accident, or 
  • Cannot be completely discounted as a contributing factor to the accident or incident. 

Because the covered employees are so vast, employers need to determine IF the employee contributed to the accident. It’s important the determination is made promptly to meet the timelines for testing required by the regulations.
