Risk Matrix #152: What the Watson Grinding Explosion Teaches Us About Process Safety
“This is not an incident primarily about a hose being left on at night. It’s bigger than that.”
A hose disconnected overnight. Employees arrived the next morning, smelled gas, communicated their concerns to management, and were never evacuated. The building exploded.
In this episode Dr. Logan F. Martin and James Junkin walk through and discuss the Watson Grinding explosion in Houston, Texas, the Chemical Safety Board investigation, and the Harris County jury verdict that awarded $61.5 million against the defendants, including 30% against contractor 3M through its ownership of DECCOM, which inspected and serviced the gas detection system that was not functioning properly.
KEY TAKEAWAYS
- The CSB report is Exhibit A in the courtroom. When the Chemical Safety Board investigates a catastrophic incident, their findings do not stay in the safety world. They become the foundation of civil litigation. Every mechanical integrity gap, every management of change failure, and every unanswered email becomes evidence of what the organization knew and when.
- Contractor liability does not stop at the fence line. 3M’s subsidiary DECCOM was responsible for inspecting and servicing the gas detection system that failed. Thirty percent of a $61.5 million verdict went against the contractor. The contract did not protect them. What they knew, what they inspected, and what they documented did.
- When safety failures leave the fence line, the community becomes a plaintiff. Watson Grinding’s explosion killed workers, injured community members, and destroyed homes and businesses. Civil liability in process safety incidents extends far beyond OSHA jurisdiction. The jury is not limited to what OSHA can fine.
