Refinery Fire Kills Five in Oily Waters
18 Mar
Summary
- Five people died outside the Olmeca refinery in Tabasco.
- Oily waters around the refinery perimeter caught fire, causing the deaths.
- Heavy rains contributed to oily water overflowing and igniting.

A devastating fire outside the Pemex Olmeca refinery in Tabasco has resulted in the deaths of five people. The incident, which occurred on Tuesday, March 11, 2026, involved "oily waters" that had accumulated around the refinery's perimeter. These waters ignited, leading to the fatal blaze. Among the deceased was a Pemex worker.
Pemex attributed the accident partly to heavy rains, which caused oily water to overflow and pool outside the facility's fence. The Olmeca refinery, located in the Gulf port of Dos Bocas, is one of Mexico's largest. It began operations in 2024 but has experienced operational challenges and processing capacity issues.
