What!!!!

No hydronic!!!!

They did not account for all those rotting carcasses. You can turn loose one rat dog and he'll kill 100 in 30 minutes and you'll harvest the corpses for fertilizer or hog feed. They could use CO2 as a simple asphyxiant displacing the O2. The rat will not displace as CO enters because they cannot detect it. If they detect it getting harder to breathe, they may be motivated to move to fresh air where the dogs are waiting. Just monitor the ambient O2 below the knees to ensure the dogs get sufficient oxygen. Once the space is clear, you can ventilate and re-occupy quicker because even if you huff a little carbon dioxide, your lungs will clear it right away. You don't have to worry about the half-life as you do with CO and CO2 does not disrupt O2 binding with hemoglobin the way CO does. As long as O2 is present, it will be transported to the cells. A little short term hypercapnea only makes you breathe a little faster and deeper.

is it approved to use it like that? it seems way too fragile for that application.

I don't think copper tubing is rated for the pressure of the propane bottle, i think at least a first stage regulator needs to be before the copper tubing.

the store involved could not produce service records. That leaves them with no defense.

Those are freeze burns.

From what I read...he "jumped on the grenade" to save others...25 surgeries? Pay the man. Mad Dog

Kroger has had some negative publicity lately, much of it revolving around its attempt to merge with Albertsons, closing a bunch of stores, and some "interesting" pricing practices. I can't help but wonder if this was the result of a chain-wide practice of deferring maintenance.

With regard to getting people away from the leak, I would have done the same thing. That was a life-threatening situation.

You would have to go over extensive legal documents to get the 100% full story. IMO if you own a building that is open to the public, or if you invite someone into your building/home and your negligence leads to their injury/death, you should almost always be held accountable. I don't think there is enough info here to say the tech should have known he would get hit with r22, so not sure how he would have known to be wearing gloves. Odds are good if the tech hadn't sacrificed his hands it could have been someone elses face in there.
