Yep..I have never used "Dry Ice"...What I want to do is use the dry ice in 80 quart coolers to keep my block ice from melting.. I'm not sure of what hazards can happen..I know the ice is around 100 below zero..I think my biggest concern is what ever gas is released and building pressure in the ice chests..SO..Is this a bad idea?..If any of you have done it what precautions do you take?...Thanks

You would have to leave the lid cracked or it will blow the lid off. We have used water and dry ice in gator aid jugs to remove small stumps. Kinda of sketchy and sensitive stuff.

No build up of nitrogen (dry ice is frozen nitrogen) nope...it's frozen CO2 (oh, the Horror!) Ooops, my bad. I was thinking freeze branding and hygienic testing bees I guess. That uses liquid nitrogen.

My main customer uses dry ice to ship all over the US and overseas. He gets thousands of pounds of dry ice delivered a month. Dry ice, in large amounts is fairly dangerous. It can build up pressure and explode a tight container. He lost one freezer that was to tight. The damage was fairly minimal, but enough that he trashed it.
Since carbon dioxide is heavier than regular air, if used in something like a chest freezer, the fumes stay in the freezer and can suffocate you, if you lean inside to move things around while breathing.
Chest freezers, that are not locked, will "burp", where the lid goes up and lets the carbon dioxide fumes creating pressure, out.

Yep..Do you think that 10lbs of dry ice would keep ice froze for 10 days at 80 during the day and 60 at night?..I know this a loaded question with a lot of variables..that would be losing a pound a day..I would be leaving the lid unlocked for the off gassing of CO2..what do you think?
Still using a 80 quart cooler..

A pound a day evaporates out of a cooler..........we used it to collect mosquitoes..........so be prepared for a few followers to come your way. And it is great for a tick trap.

Yep..I'm just gonna roll with it..whatever I get is OK on this run..when I loose all the ice it will be canned goods and freeze dried meals..
I have one more little question..I don't think you put the dry ice on top of regular ice right? or do you..If I wrap the dry ice is something will that help keep the dry ice?..

My customer gets the dry ice in paper bags, with sheets of paper between the thin, layered dry ice, so you can select how much you want. He ships frozen meat in a cardboard box, with styrofoam sheeting on the top, bottom and sides, with insulated side panels, inside the styrofoam, that look like they are made of padded space blankets. The frozen meat goes in a heavy duty, garbage bag, in the center and the dry ice is placed on top of the meat. The bag is folded over, but not tied. The meat will stay cold that way for up to 5 days.
Since cold air falls, it makes sense to put the dry ice on top, but it probably does not matter much in a small, insulated container.

It's not as dangerous as long as your somewhat knowledgeable. It's sold in the local grocery stores here. As mentioned, wrap the chunks in newspaper for handling. Minimize air getting to it so it does not evaporate too rapidly. I had a deer head to wide to put in my standup freezer. I took a regular 64 at igloo cooler stuck the head in it, layered the dry ice around it, then packed the pink house insulation around ice and head. Lasted at least a week until I took the head to the taxidermist and froze it solid. We use dry ice in bulk at work to help fit bearings and sleeves on shafts. As long as you don't see the fog oozing out of your cooler it will last a good while. I wouldn't crumble it and put it in plastic bottles though.
