A refinery explosion and fire were reported Friday, May 8, 2026, at PBF Energy’s Chalmette refinery in Louisiana, near New Orleans. According to Reuters, two sources familiar with plant operations said a heater on a reformer at the refinery exploded, setting off a large fire. The explosion reportedly happened in a 17,500-barrel-per-day reformer unit at the 190,000-barrel-per-day refinery.
Early reports stated that no injuries were reported and that everyone working in the affected area was safe and accounted for. Chalmette Refining also reported that fence-line monitoring showed no off-site impact.
The explosion occurred at approximately 12:51 p.m. CDT. Video posted online reportedly showed flames and thick black smoke rising from the refinery after the blast. St. Bernard Parish officials said the fire had been contained by about 2:30 p.m. CDT.
The Associated Press reported that residents near the Chalmette Refining facility heard an explosion around 1 p.m. and that the St. Bernard Fire Department worked with refinery personnel to bring the fire under control. AP also reported that emergency response teams remained on site and that officials said no toxic chemicals had affected air quality.
Local news outlets reported that fire crews remained inside the refinery Friday afternoon, cooling tanks with water after the explosion and fire. Witnesses reported feeling the blast nearby, including ringing ears and ceiling tiles falling near St. Bernard Highway.

What is a Refinery Reformer?
A reformer is an important refinery unit used in the gasoline production process. Reformers convert refining by-products into octane-boosting components used in premium and mid-grade gasoline.
The U.S. Energy Information Administration explains that reforming uses heat, moderate pressure, and catalysts to turn naphtha into high-octane gasoline components. Because reformer units involve heat, pressure, fuel streams, and complex refinery equipment, explosions or fires in these units can raise serious safety and maintenance questions.
At this time, officials have not reported a final cause of the explosion. Chalmette Refining has said that the cause of the incident will be investigated.
Chalmette Refinery Explosion Cause Remains Under Investigation
The cause of the incident is unclear at this time. However, refinery accidents are often due to equipment failure, maintenance issues, operator error, and contractor activities. In major refinery incidents, investigators may review:
- Equipment inspection and maintenance records
- Heater, piping, valve, and pressure-control systems
- Alarm history and control-room data
- Hot work or contractor activity in the area
- Process safety procedures
- Emergency response timing
- Air monitoring and community impact reports
- Whether prior warnings or abnormal conditions were documented
Why Refinery Explosions Are So Dangerous
Refinery explosions can be extremely dangerous because workers may be exposed to fire, blast pressure, toxic smoke, chemical releases, falling debris, and secondary explosions. Even when no injuries are immediately reported, refinery incidents can create serious risks for nearby workers, contractors, first responders, and surrounding communities.
The Chalmette refinery is a major industrial facility. AP reported that the refinery processes about 189,000 barrels of crude oil per day, produces specialty chemicals, and has about 500 employees and 200 contractors.
