San Jose firefighters investigating after recycling facility partially collapses

SAN JOSE, Calif. (KGO) -- San Jose firefighters are investigating after a recycling facility roof partially collapsed on Friday.

Authorities say firefighters were first called to the 200 block of Leo Avenue just after 3 p.m.

Video from SKY7 shows a roof caved in at a construction materials recycling facility warehouse south of Happy Hollow Park & Zoo.

Firefighters say all employees are accounted for and drones were used to determine that nobody was trapped under the debris. There are no reports of injuries, and the scene was deemed "under control."

The fire department says a front loader operating inside the building hit a support beam. The beam collapsed and that brought down the entire roof.

"We had some of the tresses come down in the middle that is basically holding up the walls up," said Battalion Chief Brett Maas with San Jose Fire Department.

"It go in, seconds in, goes fast. All the building down. It didn't take five minutes. It took seconds. The entire building down on the floor," said customer and eyewitness Armando Alvarez.

Alvarez says he was moments from entering facility.

"It's crazy that these things happen. I'm very lucky. It's my lucky day," said Alvarez. "I turned my back. All the noise -- it was shaking the floor, it was shaking the floor."

Officials say the building has been red-tagged.

"The main structure -the support of this building are those I-beams holding it up. At this point, with the wind and things like that, those walls are free-floating. There's nothing holding them up. We could have a secondary collapse," said Maas.
