"I heard explosions. The warehouse is on fire," neighbor Patrick Petrillo said.
It was Petrillo's middle-of-the-night unnerving wake-up call.
"What did it look like?" I asked him.
"It was 200 feet in the air. Higher than those poles, and I knew it was done," he said.
The fire erupted in the 4800 block of Kernsville Road, in North Whitehall Township.
"Have you ever seen a fire like this?" I asked Fire Marshal Don Jacobs.
"No. Not this intense," he said.
He says two trucking companies, Doctor Diesel and OCS, and a cleaning company used the space.
"All the diesel fuel for those, they have all the hydraulic fluids that are going to be associated with the hydraulic lift, all that stuff, and all that stuff is at some temperature combustible," he explained.
