Tank leaking toxic chemicals in OC will spill or explode: Officials

GARDEN GROVE, Calif. (KABC) -- Emergency crews are sending an urgent warning that a chemical leak coming from a large storage tank at a Garden Grove aerospace facility could cause a spill or explosion.

Authorities are calling the toxic chemical leak in Garden Grove a "crisis situation," triggering evacuation orders for roughly 40,000 Orange County residents and school closures.

AIR7 video from overhead on Friday shows unmanned fire hoses and an automatic sprinkler system spraying water on the overheated tank, which is facing a potential catastrophic failure.

The tank at GKN Aerospace is carrying a highly toxic and flammable chemical used to make plastics. Now, fire crews say the tank is going to fail in one of two ways: either with a spill of thousands of gallons of toxic chemicals or an explosion. Authorities just don't know when or how it will end.

"There are literally two options left remaining," Orange County Fire Authority (OCFA) Division Chief Craig Covey said. "One, the tank fails and spills a total of about 6,000 to 7,000 gallons of very bad chemicals into the parking lot in that area, or two, the tank goes into a thermal runaway and blows up, affecting the tanks that are around them that have fuel or the chemicals in them as well."

Covey stressed that "there is no active gas leak, no plume in the area," but he warned residents to heed the evacuation warnings and remain out of the area due to the possible spill or explosion. Officials said air quality was being actively monitored in the area, and all readings were still within healthy limits.

No injuries have been reported as of Friday afternoon.

It was unclear what initially caused the material in the tank to overheat.

Evacuees face uncertainty amid chemical tank crisis: 'We all want to go home'

More than 40,000 people are under evacuation orders as a result of the chemical tank crisis in Garden Grove.

The line of evacuated residents stretched out the door at the shelter set up at Freedom Hall in Fountain Valley.

More than 40,000 people are under evacuation orders as a result of the chemical tank crisis in Garden Grove.

Neighbors joined forces as they searched for hotel rooms after the sudden called to evacuate their Orange County homes due to the danger.

"Got a knock on the door, and I was told we were supposed to leave so I did what I was told," said Jason Reid, who went to one of the shelters.

Neighborhoods across Garden Grove, Stanton and Anaheim suddenly became ghost towns.

After rushing out in the morning, some residents like Diego Espinoza and his mother were allowed to return briefly to grab medication and other vital supplies.

"I feel like the situation has escalated very quickly," Espinoza said. "It was pretty harsh to get out of the house very quickly. We forgot a lot of stuff. That's why we came back here."

While most have heeded the warnings, some are staying behind.

Several shelters have been set up for residents and their pets, with everyone worried about how long they may be out and what could happen to their neighborhoods.

"I think that's the worst part - just waiting and not knowing what's going to happen because we all want to go home," said Jacqueline Reigos, who also had to evacuate.

Fire official says crews making progress cooling tank

Craig Covey with the Orange County Fire Authority provided an update Friday evening, saying his team has made progress in cooling the tank.

"The focus that we have been telling our team is to think outside the box... In the last four to five hours, they've come up with some tremendous ideas that we're going to start taking action on as soon as possibly tonight," Covey said.

He added that their efforts have resulted in cooling the tank, with the temperature down to around 61 degrees, with "50 (degrees) being its happy place."

"Those efforts are succeeding, and it's giving us opportunity to reconsider engaging in close proximity to implement some of the concepts that were outside the box... and we can go in there and mitigate this thing," Covey said.

"It is not OK with me just to sit back and watch this thing blow up or fail. That is not acceptable to me," he added.

Crews will be working overnight, and the next update will be provided Saturday morning.
