A large fire at the Delta Air Lines-owned oil refinery in Trainer, Philadelphia, has resulted in injuries to four employees, according to local media.
On June 25, 2026, the Delta Air Lines subsidiary, Monroe Energy, confirmed that the fire began in a process unit pump room at around 11:30.
Emergency crews were deployed to the incident scene and local residents were told avoid the area until further notice.
Delaware County officials later advised that the blaze was extinguished by firefighters at 13:30 and that a shelter-in-place order was lifted at 15:00.
In an initial statement, Monroe Energy declared that, as a result of the fire, one employee had sustained non-life-threatening injuries and had been transported offsite for medical treatment.

According to NBC10 Philadelphia, officials from Monroe Energy later advised the news station that four employees had suffered non-life-threatening injuries. One of the four injured had already returned home.
“When the fire began, Monroe immediately deployed air monitoring in the surrounding community in coordination with the Delaware County Local Emergency Planning Committee,” Monroe Energy said in a statement. “While smoke was visible, air monitoring results showed that there were no risks to human health.”
The company stated that the health and safety of the local community are “paramount” and that it is “continuing to work closely with local emergency response officials”.
“While we do not know the exact cause of the fire at this time, the incident will be fully investigated,” Monroe Energy said.
Strategic importance of Delta’s oil refinery
In April 2026, Delta announced its March 2026 quarter financial results, against the backdrop of the war in Iran and the subsequent surge in oil prices.
Addressing the conflict in the Middle East, Delta claimed that it was “best positioned to navigate this environment,” in part due to the benefit of its oil refinery.
At the time, Dan Janki, Delta’s COO said: “The refinery is expected to provide a $300 million benefit to the June quarter at current prices.”
During the height of the fuel crisis, Delta was praised for its strategic decision to purchase the refinery in 2012.
The crude oil processing capacity at the refinery is about 185,000 barrels per day and accounts for around 75% of Delta’s total jet fuel demand, according to OPIS.
