CSB investigation points to lack of training, robust safety rules in H2S deaths
The U.S. Chemical Safety Board (CSB) released a safety video in August on a fatal hydrogen sulfide (H2S) release that occurred in Odessa, Texas, in 2019. The accident occurred at a waterflood station, a type of oil and gas processing facility that treats wastewater, known as produced water. It killed a pump operator who was working at the facility in the evening, along with his wife who came looking for him when he did not return home. The deadly gas had escaped through a leaking pump.
H2S is a gas that is immediately dangerous to life and health and the CSB says the lessons from this incident apply to a multitude of other oil and gas processing facilities throughout the country. Oil and gas facilities are urged to understand the findings from the CSB’s investigation and to implement appropriate safeguards and training.
The CSB identified six safety issues that led to the fatal incident:
- The pump operator was not wearing his personal H2S monitor at the time of the incident.
- The company did not have written lockout/tagout procedures, but relied instead on verbal procedures without formalized training.
- Ventilation inside the pumphouse was inadequate, allowing the fatal buildup of H2S gas.
- The company lacked a comprehensive safety management program.
- The facility’s sensors and monitoring system were not functioning properly on the night of the incident.
- The company had deficient site security. The ineffective site security allowed the employee’s wife to enter the facility.
