CORNING, Calif. -

A fire erupted at a mobile home in Corning early Thursday morning off Highway 99 West near Chase Avenue that burned toxic chemicals and destroyed several structures.

Firefighters said no one was inside the mobile home when it caught on fire, and they think there's something suspicious about how it started.

Around 4 a.m., dozens of firefighters rushed to a mobile home and several other structures engulfed in flames.

“Some of them were mobile containers used to store items on the property,” said Matt Chamblin, battalion chief for CAL FIRE, Tehama County. “Other ones were sheds and garage type structures.”

The mobile was destroyed as well as other items found on the property. Fire officials said the blaze was so hot it took them an hour to control it.

No one was found inside and the items and materials that were in the fire produced a toxic smoke.

“There was a collection of plastics and other types household wastes that were burning,” Chamblin said.

It took firefighters 5 to 10 minutes to arrive, and they needed water tenders as well. The delay caused the fire to burn an acre of dry vegetation around the area.

“Down in this area of Corning, we don't have fire hydrants,” Chamblin said.

CAL FIRE said the area was filled with junk and witnesses told them no one lives there. Firefighters did discover that a group of people have been working to clean up the area recently.

“Until ruled out by the evidence, arson cannot be ruled out,” Chamblin said.

No one was hurt in the blaze, and the cause of the fire is under investigation.
