An 80,000 square foot San Jose warehouse was rocked by explosions Thursday, sending a massive fireball into the early morning sky, authorities said.
Firefighters were able to gain the upper hand on the dramatic five-alarm blaze after about three hours, a fire captain said.
The fire was reported at a building in the area of East Julian and North 28th streets at 5:37 a.m.
San Jose fire Capt. Cleo Doss said the first crews arrived at 5:43 a.m. He described the warehouse as a roughly 125,000-square-foot building that houses multiple companies.
The fire was contained shortly before 8:30 a.m. but there were still hot spots burning. There were about 100 firefighters at the scene, Doss said.
No injuries have been reported.
The site of the blaze is near U.S. Highway 101, where traffic slowed to a crawl as motorists gaped at the giant plume of black smoke created by the fire.
Although the highway remains open, the off-ramps to Julian Street are closed and the California Highway Patrol is advising motorists to use state Highway 87 as an alternate route.
“Anybody who’s driving by the fire who is getting through on 101 should keep their windows rolled up and not allow any outside air to come into the vehicle,” CHP Officer Ron Simmons said.
Doss said it does not appear that smoke from the fire is creating a danger to the public.
“We have no reason to believe that there’s any hazmat associated with this particular incident,” Doss said.
He said, though, that residents with respiratory problems may want to stay indoors.
Roughly 4,045 PG&E customers are without power Thursday morning because the fire department asked PG&E to shut down gas and electrical lines in the area of the blaze, PG&E spokesman J.D. Guidi said.
Guidi said he did know how many homes are without gas service. He said the fire is not believed to be PG&E-related.
Fire crews from Sunnyvale, Santa Clara and Mountain View assisted San Jose in battling the blaze.
