I've heard that running downhill is a good technique for escaping bears. You may not be able to outrun them in a climb or on level ground, but your relative speed difference is smaller when running downhill because a bear needs to slow way down to not tumble.

TEMPLE GRANDIN OS posted:practice running from cops to train for running from bears Bad advice. Cops are unwilling and unable to run quickly, making them poor for speed training. Bears are unable to operate firearms and might contribute to society. Also, bears cannot be racist, again, making them poor comparisons to law enforcement.

I am 100% going to tumble rear end over tea kettle myself and become tenderized by the rocks for an easier meal.

From the look of the practice site, it might be a helicopter fire suppressant sprayer. Possibly the only thing crazier.

What’s going on there? Some type of gas that’s heavier than air has displaced all the oxygen?

Somebody threw a bunch of dry ice in a swimming pool because it would look cool. Three people died of CO2 poisoning. https://7news.com.au/news/disaster-...moscow-c-724820 I've heard of other similar stories too. By the time you realize something might be wrong, its too late. loving terrifying.

Another way is to remove oxygen via oxidation. Voids and chain lockers on ships are especially dangerous for being low oxygen due to iron oxidation in the sealed or otherwise unventilated and mostly sealed spaces. Rusting chain just soaking up all the oxygen in the air.

Deteriorata posted:Carbon dioxide, most likely. Yeah, probably carbon dioxide. There was a temple to Pluto built in Turkey on a cave that had a CO2 leak and the priests would sell animals for people to chuck in and watch die while priests for Cybele would crawl out to "prove" they were "immune" (they knew where the pockets of breathable air were).

I know Nitrogen Narcosis is a huge issue in really deep metal industrial equipment like Nuclear reactors, including warnings about 'If suddenly see a coworker drop and fain in a deep shaft, do NOT go in after them, either pull them up by a recovery rope and alert emergency services' because multiple people died trying to recover one guy from a nitrogen rich environment and it just knocked them out one by one and killed them all.

At the old lab I worked at we would vent vacuum vessels with nitrogen. One of the workers stuck their head into the vessel after venting once and got super dizzy from lack of oxygen. Thankfully didn’t pass out because they were old and like 15 feet up on a platform. They made us vent with air after that. Kinda annoying, venting with dry nitrogen made subsequent pump downs take way less time.

When the Hebrew language was revived the name chosen for Nitrogen was picked to be חנקן , literally "suffocator". I don't know why they reserved this name for this element but it wasn't wrong. E: oh it's probably because it was demonstrated to suffocate fire on the 18th century. By popular demand fucked around with this message at 05:04 on Apr 11, 2024 |

We ran pumps that filled the headspace of vials with N2 when the drug was oxygen-sensitive but we never had trainings about it because the facility was doing ~550-700 full air changes an hour I was in 3 full-blackout power losses in those cleanrooms lol, thankfully never when N2 was running MrQwerty fucked around with this message at 05:05 on Apr 11, 2024 |

There's even drone pesticide applicators, but the holding capacity is significantly less. That makes sense, what I thought at first viewing was a fire hose looks like it might actually be a hookup for a fill line to the helicopter's tank from a much larger tank.

Strictly speaking, nitrogen narcosis is nitrogen that's mixed with normal breathing glasses anesthetizing a scuba diver because it is more readily absorbed at higher pressure. What you're describing is nitrogen at 1 atm displacing oxygen and asphyxiating someone.

Safety Dance posted:What you're describing is nitrogen at 1 atm displacing oxygen and asphyxiating someone. And the reason it’s so dangerous is that the feeling of suffocation comes from excess CO2, not from a lack of oxygen. If you’re breathing pure nitrogen you won’t build up CO2 levels to the point that makes you realize you’re asphyxiating.

Aren't there fruits that offgas a bunch of stuff that make them dangerous in confined areas? For some reason I'm thinking bananas.

Potatoes were the ones that killed an entire family. Bananas release a lot of ethylene which makes other fruits ripen (and overripen) very quickly, but it’s not a threat to people.

By popular demand posted:When the Hebrew language was revived the name chosen for Nitrogen was picked to be חנקן , literally "suffocator". In Swedish, nitrogen is kväve, from kväva - to suffocate. It was named already in 1795 because chemists found out that it could be used to suffocate fires. The name is similiar in the other Scandinavian languages.

It's similar in German where it's called "Stickstoff" (Suffocation Substance)

Hebrew was not an everyday language for a long time before the state of Israel, updating it from the purely ceremonial (think Latin) role was an undertaking. More reading: https://en.wikipedia.org/wiki/Eliezer_Ben-Yehuda
