Fatal entry into Open-Top Frac Tank (PRCS & H2S)

At 8:00 a.m. on June 26, 2022, two (2) employees emptied and cleaned an open-topped frack tank (Tank #4) at an oil and gas services site. There were no eyewitnesses, and the employees were working at a remote site alone, so few details are known about what occurred.

At the time of the investigation, hydrogen sulfide (H2S) gas was detected at levels between 3 parts per million (ppm) and 5 ppm, which is non-lethal. The two employees died. But, it is not possible to estimate what the H2S levels might have been when the employees were killed. The tank contained approximately 2 feet of water/oil.
