I would try to avoid running over him if I shook him off but I am not going to just sit around while he tries to enter the cab, I have no idea what he's capable of.

like most people, probably, I only saw the video a bit cut off and assumed that rope was also his anchor and welp SHOOSH.

The ropes have a steel mesh core and are rated to carry industrial sized roads. You could, in a very ill-advised pinch, use a climb rope to tow a car. Additionally, because of the core, it's incredibly difficult to cut through a rope with a saw. Though, should you strike your flip line with your saw, you're going to have to come down because A. Your saw is gonna be duller than church and B. You just put your very expensive climb rope completely out of commission.

Though, when I was out there leading a fuels reduction crew, we were roping a tree over when one of our not very bright sawyers cut through through the rope (base tie). Cue about eight people falling flat on their asses and the tree crushing a fence.

Though, my caveat to my own post is that arbor crews do not give a singular gently caress about safety of any kind, and I've seen real morons climb trees with bull lines (basically, climb line:upwards of 5K-25k carrying capacity with a steel mesh core. Bull line: 2-3k with no core). There's a reason why a lot of people die doing arbor poo poo year after year.

Last year, one poor arborist came out of a tree near a chipper. As he was getting out of his gaffs, his climb line got twisted in some slash. One of the chipper crew people picked up that piece of slash and put it in the chipper without realizing that the line was in the slash. The drum of the chipper caught the rope and basically yanked the arborist at about 50 mph directly into the chassis of the chipper, killing him instantly.

Just as a bit of balance to weigh against this horror, it is awesome to watch tree workers who know what they are doing, and are as safe as they can be about it. When I lived in North Vancouver, I watched a crew take down a huge douglas fir that was somehow left to grow in the tiny patch of unpaved earth between the parking lots for three low rise apartment buildings. The branches started above the height of my third floor balcony. They managed to chop up and lower the whole thing right next to the stump. I had no idea that was even possible before that.

The driver was in a situation where any action other than stopping immediately puts another human in immediate mortal risk, and he was repeatedly trying to make that WORSE by accelerating to highway speeds and trying to shake off a half-naked weirdo onto a busy highway or, just as likely, under his own wheels. If the driver feels like he's in danger from the tiny terrified half-naked filipino man on the hood of his huge locked metal box, he's a tremendous pussy. gently caress that driver.

Christ.

I had a mature oak hit by lighting that strangely killed only some larger branches on one side and very top of the tree (lightning is weird). They rolled up in kick-rear end HUGE cherry picker, did all the rigging from the bucket (dude was strapped in), had two guide teams away and each at 45 degrees from whichever part was being removed. Cut from the bucket, and the cut section was slowly lowered to the ground.

They also cut up all the removed wood into manageable 12-18 inch logs that I later easily split into almost 2 cords of firewood.

The driver had a pretty big metal object, too, and it about wrecked a lot more than the other guy's windshield. If he was truly scared imagine how much faster the cops could have reached a crime scene that was stationary

That’s true, but it doesn’t make it not poisonous. Lots of poisons are unpleasant, albeit not evoking the same visceral reaction as carbon dioxide.

Jabor posted:

Yeah the air can be twenty percent oxygen at sea level pressure, but if four percent of it is carbon dioxide, it’s lights out.

Now for a good occupational safety yarn:

quote:

Oh, boy.

Now I have to explain the absolute Greatest Moment in Wacked Out Real Science.


Couple years ago, some people I worked with finally completed a long-delayed project to build a very large vacuum chamber for testing plasma thrusters and other advanced spacecraft propulsion systems. Not the biggest in the business, but maybe top ten nationwide. Big enough to walk around inside, at any rate, which is the important point.

Important, because in order to go operational it needed the approval of the local Safety Nazis. You know the type. They have a checklist, nay, a whole handbook of checklists, one of which involves Confined Spaces. Big enough to walk around in? Check. Airtight? Check. Can be filled with asphyxiant gas? Well, the MSDS for "Vacuum" apparently lists it as an "asphyxiant", so check. It's a Confined Space, and so the Confined Space checklist must be implemented.

Issue the first: How do they make certain nobody can accidentally walk in while the chamber is full of that deadly asphyxiant, "vacuum"? No, the fifty *tons* of force holding the door closed, is not an acceptable answer.

Issue the second: When the chamber is vented back to full atmospheric pressure, where does the vacuum go? If the chamber were accidentally vented by opening the door (see above, and note exact Safety Nazi quote, "OK, say if you were Superman and you opened the door"), where would the vacuum go?

Issue the third: What assurance is there, that when the chamber is vented back to full atmosphere, there is an adequate percentage of oxygen in the chamber?

Hint: It is a big, big, big mistake here to acknowledge here that the laws of statistical gas dynamics allow for one chance in 10^10^17 (no typo) that the chamber will spontaneously refill with a sufficiently oxygen-poor atmosphere to preclude respiration.

Issue the forth, and so help me God I am not making this up, again an exact Safety Nazi quote, "How can you be sure there won't be vacuum pockets left in the chamber, that someone could accidentally stick their head into?"

And, coupled with issue #2, there could be deadly vacuum pockets floating around the lab! Aieeee!!!! Run for your lives!

It only took three weeks to find someone with the common sense and the real authority to overrule the Safety Nazis on this one, and the SNs still take offense if anyone brings it up in their presence.

Vacuum pockets.

About CO2, this isn't OSHA but a personal anecdote from my misspent youth. Somehow some idiot acquaintance ended up buying CO2 cartridges instead of nitrous cartridges (we did a lot of nitrous sometimes). Out of curiosity and bravado I decided to see what it would be like to inhale a CO2 cartridge. We had those whipped-cream makers where you just fill the container with gas and then inhale it, if I recall - using balloons was something we moved on from pretty early.

I took a big lungful and then experienced a weird sensation as it felt like my breathing reflex just turned off. It wasn't uncomfortable, and I don't remember getting light-headed or anything, it just felt like I didn't need to breathe. I exhaled and it passed in a minute or so and with no ill-effects that I can recall, but it was a weird feeling. If memory serves healthy breathing is more based on CO2 concentration than oxygen, so I assume the sensors just got flooded for a bit and didn't send the right signals. It did give me an object lesson in what I already was intellectually aware of, that dangerous gaseous environments can be really hard to sense and can sneak up on you.

In terms of their windshields there's not all that much difference.

But it doesn't matter, and I'll fully concede that the man was an idiot to be panicked, because it turns out the early reports were wrong and the guy didn't have a metal implement of any kind, just his fists.
