The line being tied off to their little bobcat thingy and only using the other tree for a landing point is genius. No chance of the branch smacking into the tied line or knot and messing it up.

Oh I realised the real reason for tying off on their bobcat. Don't have to keep re-tying it as you work down the tree.

RandomBlue posted:That and spending $60k on a car is disgusting.  If you can get a car that you like, that doesn’t have giant maintence issues and has good safety features that’ll last a long time, there’s nothing wrong with spending 60k on a car. Yeah, it loses value quick but if you’re fine with that, go hog wild. Without people being willing to drop 60k on a car there never would have been enough demand for hybrids and EV’s to have models coming out in the 30k range. If you’re some 18 year old fresh out of boot camp spending 60k on a car with a sticker price of 30k, ok, that’s gross but that’s more on the dealer than the buyer.

There was a bunch of russian bloggers or instagram people or something who basically did that to themselves about a year ago. Were having some party and threw a bunch of dry ice in the pool for the cool fog and basically asphyxiated themselves. Bunch of people in the hospital, at least one dead iirc. It hit the news because one of the dead people as the husband half of some russian social media couple. edit: I think some people in the pool also got acid burns or some other kind of chemical burn from it? it was hosed up.

I mean, oxygen displacers aren’t really poisons if you want to get technical. Like, if you’re in a room that gets flooded with argon, the argon’s not what’s killing you. Technically. E: from the dry ice SDS:

Dry ice is CO2 though, so its not just an oxygen displacer? Also I dispute that claim by the manufacturer - I worked in a lab that had -70 degrees dry ice freezers, and I picked up a metal rack from a freezer wearing PPE gloves and held it against my chest to balance. Unfortunately, I had nipple piercing at the time, and it turns out even through a lab coat a metal piercing drops temperature pretty quickly...

It binds to red blood cells and prevents them from taking up oxygen or removing carbon dioxide from the body. It’s a poison.

Platystemon posted:It binds to red blood cells and prevents them from taking up oxygen or removing carbon dioxide from the body. That’s carbon monoxide. Dioxide does bind to hemoglobin in small amounts but it’s way less polar than monoxide so hemoglobin lets go of it much easier. Monoxide kills you because it binds really strongly to hemoglobin and other things can’t knock it off. You have to really, really skew the equilibrium towards O2 to treat that, hence the hyperbaric chambers for treatment. If dioxide bound that strongly to hemoglobin, you wouldn’t be exhaling it. CO2 is marked as a simple asphyxiant on the diamond with a 2 on the blue square, mostly for the frostbite and tachycardia risks on top of the asphyxiation hazard.

CO2 is definitely poisonous, too much of it will kill you even if there's still sufficient oxygen in the air. Sure, it's less poisonous than carbon monoxide, but that doesn't make it benign.

Jabor posted:CO2 is definitely poisonous, too much of it will kill you even if there's still sufficient oxygen in the air. It’s not 100 percent benign or anything, but it’s also the kind of thing where if there’s a leak, the symptoms set in and make you GTFO unless it’s a high enough concentration to asphyxiate you. If you look at the OSHA reports on CO2 leaks it’s basically split between “first aid/treated and released” and “super dead” usually with some additional fatalities from rescuers going in when they see someone drop. It’s not even something that’s in the standard 4-gas detector for confined spaces because it’s not something that’s really going to kill you on its own. It’s the low O2 alarm that’s gonna go off for that one. So, yeah. Slightly poisonous but not really acutely toxic. The human body is really good at compensating for excess CO2.

Ornamental Dingbat posted:Apparently an image from the Russian pool party Yeah when that originally happened we did the math with the amount of dry ice they reportedly had and determined that the CO2 concentration in the entire room, if the air were well-mixed, would be over 10% -- and 4% is considered immediately dangerous to life. Of course because CO2 is heavier than air and a pool is flat, it would be a gradient with maybe non-lethal air at the top of the room, but the concentration at the water's surface was probably close to 100%. Craptacular posted:It looks like the gear is being heat treated and and then quenched. Yep. Specifically, it looks like they are trying to harden the teeth so that they don't deform or wear down from interacting with the chain, while leaving the body of the gear somewhat softer so that it can handle the shock of the driveline without cracking.

The body is also really good at detecting concentrations of CO2, that panic reflex you get when you hold your breath long enough is triggered by high CO2 in the lungs instead of low O2. If it hasn't displaced so much atmospheric oxygen that you immediately pass out your lizard brain is gonna break limbs trying to get the gently caress out of there.

If it hasn't displaced so much atmospheric oxygen that you immediately pass out your lizard brain is gonna break limbs trying to get the gently caress out of there. Fun fact, that often doesn’t work in people with COPD, where the chemoreceptors end up looking for low oxygen instead of high CO2. Though if you have emphysema and are around a CO2 leak you’re probably boned anyway.

WarpedNaba posted:I thought it just detected CO2 levels by PH analysis? CO2 levels in COPD patients are typically high enough to desensitize the receptors that detect high pH, so the hypoxic drive takes over. The lower overall oxygen level they have going on also sensitizes the peripheral receptors in the carotid/jugular arteries, which primarily detect O2. They end up taking more, shallower breaths because of the shift. COPD is one of those terrifying diseases that just seem like a living hell.
