Blast zones identified as Garden Grove chemical tank inches toward explosion
California Post ^ | 5/23/26 | Ross O'Keefe

Posted on 05/23/2026 4:42:20 PM PDT by Libloather

Fire officials have released a clear and haunting view of what damage could look like if the toxic Garden Grove tank explodes, with its temperature increasing with each passing hour.

OCFA Division Chief Nick Freeman said Friday that blast zones would be divided into severe, moderate, and light blast zones in a radius around the tank.

The most severe blast zone will cause “severe structural damage and significant harm,” while the moderate zone will see structural damage and some harm. The lightest zone will see just some structural damage.

In addition, an oblong circle above the tank is divided into three zones representing further hazards caused by the chemicals: a red, orange, and yellow zone.

The red zone is the most lethal, representing a flammable area that could see fire or flash fires. Orange is still threatening and could cause injury to anyone who inhales the chemicals. The yellow area represents spots where residents could smell the vapors, but they would not be dangerous.

Dr. Regina Chinsio-Kwong was also at the news conference and said anyone smelling the chemicals will get notes of a strong fruity odor. But she said smelling the odor doesn’t mean you will have symptoms.

“We actually do know that when you smell it, you don’t typically have symptoms, and when you actually measure the levels in the air, it doesn’t mean it’s dangerous,” she said. She also urged people to evacuate and said a precautionary mask is unnecessary outside the evacuation zone.

She previously said the chemical involved, methyl methacrylate, can cause “significant irritation in the lungs, the nasal passages,” along with nausea and dizziness. Heavy doses of the substance could “cause severe respiratory distress and hospitalization.”

I understand the terminology for the “odor” but doesn’t explain the “notes.” Just strange - not important...

They are keeping water on the tank.. but it’s insulated, and the energy inside is increasing faster than the heat can transfer out through the walls.

I’d bet they’re looking for some kind of super-cooled liquid, but the would be a longshot, and they’re running out of time

I thought that fire regulations are set up so that if you are storing something that requires more than "water from a hose" there was supposed to be notification to the fire department and a plan for protection in the event of an emergency.

Does this mean that California needs more regulations?

The fragrance of orange blossoms on the way to Disneyland from San Diego was pleasant. A bygone memory now.

I assure you, they had an emergency plan that has been reviewed by multiple government agencies. This is a rare event that could only happen because of multiple system failures. The accident report will be interesting.

Something screwed up …. Bigly

An emergency plan for chemicals that does not address possible explosive release of the chemicals and how to mitigate outcomes is not much of a plan. It's possible that there is a plan but the authorities can't find it right now, but more likely the whole thing just got blown off. Or there is DEI involved at some point, or just government incompetence.

But, as you mentioned, the after report should be interesting. Depending on who writes it, and who approves before release. Could end up looking like the dem autopsy on the 2024 election.

Commonly used term in medical and chemical subjects. Means exactly what it says.
Diabetics who burn fats for energy, produce ketones, acetone being the most produced , and their breath has a sweet , fruity odor, or a nail polish remover odor...it could signify development of diabetic ketoacidosis, meaning get over to the ER ASAP.

From the wiki page on the incident.

Representative Derek Tran of California’s 45th congressional district, which includes Garden Grove, said on May 22 that he had spoken wRepresentative Derek Tran of California’s 45th congressional district, which includes Garden Grove, said on May 22 that he had spoken with GKN Aerospace leadership and “urged the company to take full responsibility”.

This is a very Asian view of industrial accidents. Every accident must have a culprit to be held responsible. Some are do to bad management, but not all. Derek Tran is assuming this a a function of bad management.

There was a silo expolosion in Searsport Maine a week ago. The fire did not start with the silo, but in a nearby building. The cause of that fire and its effect were two separate things. I have no idea what caused the orginal fire, but once going it was not a management decision that caused it to spread to the silo. It was the nature of fire.

They are still following the plan: The “when all else fails” portion involves, evacuation of people from the endangered area. That’s what they’re doing. Buildings can be replaced... people can’t.

To get to this point, at least two layers of protection have already failed. This isn’t SUPPOSED to be happening. Sadly, it occasionally does, but it’s very rare.

It is shocking to me, being from Texas, to see so many people living so closely to MMA storage tanks. yikes!

As I recollect, a faulty valve is hindering safety efforts.

A picture of the problem (not merely of the tank) might enable some to suggest a solution.

“’notes.’ Just strange”

I suspect you are not a wine lover or perfume maker.
