@mcbreeezy Most likely what they meant was that you need your extractor in a c1d1 area with all auxiliary chillers, heaters, etc. piped in from outside. Within the extractor you will bring the solvent amount in the extract to a level where it doesn’t give off any Lower Explosive Level(LEL) reading, once it’s at zero you can transfer it into a pryex. When the pyrex is at 0% LEL, you can move it into a post processing area, to remove the last bits of solvent in a vacuum oven. This is how Denver County does it, no pours what so ever.

your vacuum oven does not belong in the extraction booth. neither do your chillers or heaters. if your booth builder doesn’t understand that, you probably need a new one (booth builder, possibly booth if they’re that clueless).
some jurisdictions will get twisted on the vacuum pump. if it’s outside the booth, and your operator does something dumb like sucking on your receiver while it’s full of solvent, where does that solvent go, and what happens next?!? If it’s inside the booth, it needs to be rated for it.
All penetrations need to be signed off on by the engineer who certifies the booth. so put down that drill…

yeah im right there with you. im still seeking clarity from the city about all of this but i keep hearing from the fire marshal that they want the vac oven and pump inside the room. i have repeatedly told them this makes no sense. working with them everyday to get eveyone on the same page. oklahoma city is new to this and really over doing it

thank you for that info. you cant pour in the c1d1 area? i thought that was the point lol
Yeah Denver can be extreme, one of the fews that have shut down multiple labs for capping jars. I think being one of the first legal states, they regulated to the max to avoid any negative incidents. Yeah they tell you that you gotta scrape it out, because if it has enough solvent to pout it then it’s got too much solvent still in it. They make you take a LEL reading before taking out of the vessel and before taking it out of the c1d1 area.

Let us know how it all ends up, I am from OKC so I’m curious of the lab regulations especially how fast the industry took off.

They do make explosion proof ovens. They cost as much as you would expect.

So expensive they didn’t want to list the price

Could be placed in a c1d1 unit with chiller/heater plumbed in

I actually want one now, just because.
That’s going to be really hard to pitch and get put on the budget…

Like most lab equipment manufacturers, i think they kind of just think why bother posting a price. If someone is really serious they will inquire.

Go all the way with an explosion proof chiller and heater. Pretty soon you can extract out in the open on Saturn and not have to worry about blowing yourself up. Next stop, explosion proof bongs.
