We got to speak with a firefighter today and ask direct questions about the garden grove chemical leak at the evacuation center at John F Kennedy High School. I asked him if the evacuation radius is based on JUST that tank (and maybe the two next to it) exploding — or if it’s —

@Hazeludw It’s too expensive to leave 💔💔💔 I’m gonna get hungry and then have to buy food. The combo is $16. Later I have to go to the bathroom so now I gotta buy something somewhere for them to let me use the bathroom. Then I run out of gas and now I gotta buy gas—

[grace @graavvvi]

@DurhamAlli34717 I just wish we were able to ask questions you know? Because there’s no way to know why they didn’t try something like that without an explanation

[grace @graavvvi]

I’m confused on why they didn’t think to make a controlled vent for the garden grove chemical incident KNOWING that pressure was the driving factor for an explosion…. Could they not have used a water saw since that basically eliminates risk of sparks ??? Idk man it was weird

[grace @graavvvi]

@DurhamAlli34717 And the Germany example I gave was extremely similar. The only difference is the crack would have leaked flammable vapor. Yet air still would have escaped first due to its lighter density as we saw from the crack that formed naturally. Less pressure = less heat = less vapor

[grace @graavvvi]

@DurhamAlli34717 From what I’ve learned, it absolutely could have worked. There has been several similar situations in the past — and disaster analysts afterwards came to the conclusion a water saw would have worked. But they were scared to try anything new at the risk of liability

[grace @graavvvi]

From what I’ve looked into it’s been done in a similar scenario in Germany, but the idea may have been dismissed because the fire department is quite literally trained to not try anything new & against protocol. Yet their current protocol (spraying water) typically doesn’t work

@LynchDakot6483 @OCFireAuthority Hahahah yea 😭

[grace @graavvvi]

@ErikaMaldoy7fh @OCFireAuthority Yea I understand it’s probably because the temps dropped reasonably enough to believe there’s no polymerization occurring — but they need to SAYYY THAT THEN. And say what the temps cooled down to… instead of hoping we blindly accept it 😭

[Erika Maldonado @ErikaMaldoy7fh]

@OCFireAuthority So… what exactly changed? Because going from ‘possible explosion’ to ‘nothing to see here’ with zero explanation is wild.

@Neat6126 Least obvious rage bait

[grace @graavvvi]

It’s insane how much they prioritize hating homeless people over ANYTHING else, even in crisis 😭

[CAStateParksOC @CAStateParksOC]

For evacuees of the chemical spill emergency in #GardenGrove, please do not go to state beaches to stay overnight. State beach parking lots are not approved evacuation centers and do not have the facilities or resources to accommodate overnight guests.

@mattizzo @OCFireAuthority Sorry for the confusion hahaha in the orig video, she had said the evacuation zone was based on BOTH an explosion or a spill scenario. So I was confused why the border shrunk when only one is off the table. But they were just going off the maximum reach which would be the BLEVE

[grace @graavvvi]

@mattizzo @OCFireAuthority I did more digging, the old evac zone was based on how far vapor could travel in the BLEVE scenario. It was not accounting for subsequent explosions/chemical reactions. The new one is the same— based on the vapor from a gas explosion with THAT amount of product— no other factors

[grace @graavvvi]

However, the old evac zone was still NOT accounting for a domino effect/subsequent explosions. And this one is not either. However, it is much less likely there would be a domino effect. They are using a water wall to stop interaction with other buildings and materials

[grace @graavvvi]

Update:
• the old evac zone was a MAXIMUM, based on how far the vapor COULD have spread if BLEVE occurred
• smaller explosion = the vapor won’t be able to travel as far. And if it spills— the surface area of the vapor can be minimized by collecting the liquid

[grace @graavvvi]

@cryptokiq @OCFireAuthority Like everyone was upset the zone was SO big so they posted a vid explaining why. And that was their reasoning. I guess we’re not allowed to ask questions though about life threatening chemical spills my bad gang 🙂‍↔️

[grace @graavvvi]

@Izzy_Kiradihunt Of course!! 🫶 although it seems it’s not much of a concern anymore since they confirmed it is dropping in temperature :) still good to know all the details

[grace @graavvvi]

@magnifico_lr Thank you haha 🙏 I’m happy the info has been helpful for people
