PHILADELPHIA — A devastating blast at a nursing home near Philadelphia resulted in at least two fatalities. The explosion caused part of the structure to collapse, unleashed roaring flames, and left several individuals trapped inside, according to officials.

In a press briefing held hours after the incident, Pennsylvania Governor Josh Shapiro confirmed that the explosion had claimed at least two lives.

The catastrophic event occurred at the Bristol Health & Rehab Center in Bristol Township while a utility crew was on-site investigating a reported gas leak. The exact cause of the explosion remained undetermined hours later, as did the full scope of the casualties.

As the situation unfolded, emergency responders, accompanied by fire trucks, ambulances, and earthmoving machinery, hurried to the nursing home to provide aid and control the situation.

Bucks County emergency management officials said they received the report of an explosion at approximately 2:17 p.m. and said a portion of the building was reported to have collapsed. Ruth Miller, a Pennsylvania Emergency Management Agency spokesperson, said her agency had been informed that people were trapped inside.

Willie Tye, who lives about a block away, said he was sitting at home watching a basketball game on TV when he heard a “loud kaboom.”

“I thought an airplane or something came and fell on my house,” Tye said.

He got up to go look and saw “fire everywhere” and people escaping the building. The explosion looked like it happened in the kitchen area of the nursing home, he said. Tye said some of the people who live or work there didn’t make it out.

“Just got to keep praying for them,” Tye said.

The cause of the explosion was unclear.

The local gas utility, PECO, said its crews had responded to reports of a gas odor at the nursing home shortly after 2 p.m.

“While crews were on site, an explosion occurred at the facility. PECO crews shut off natural gas and electric service to the facility to ensure the safety of first responders and local residents,” the utility said in a statement.

Nils Hagen-Frederiksen, press secretary at the Pennsylvania Public Utility Commission, said investigators from the safety division were headed to the scene.

Hagen-Frederiksen said first responders and emergency management officials were describing it as a gas explosion, but that won’t be confirmed until his agency can examine the scene up close.

Musuline Watson, who said she was a certified nursing assistant the facility, told WPVI-TV/ABC 6 that, over the weekend, she and others there smelled gas, but “there was no heat in the room, so we didn’t take it to be anything.”

The 174-bed nursing home is about 20 miles (32 kilometers) northeast of Philadelphia. Its owner, Saber Healthcare Group, said it was working with local emergency authorities. The facility had been known until recently as Silver Lake Healthcare Center.

The latest state inspection report for the facility was in October and the Pennsylvania Department of Health found that it was not in compliance with several state regulations.

The inspection report said the facility failed to provide an accurate set of floor plans and to properly maintain several stairways, including storing multiple paint buckets and a bed frame under landings.

It also said the facility failed to maintain portable fire extinguishers on one of the three levels and failed to provide the required “smoke barrier partitions,” which are designed to contain smoke on two floors. It also said it didn’t properly store oxygen cylinders on two of three floors.

According to Medicare.gov, the facility underwent a standard fire safety inspection in September 2024, during which no citations were issued. But Medicare’s overall rating of the facility is listed as “much below average,” with poor ratings for health inspections in particular.
