Woo, I design gear that puts the tension load into rebar and from what I have seen almost any tall tower that is to small to have proper piles in it will have foundation bolts/bars which is essentially 30 metre lengths of rebar that poke out of the ground for like 3 feet above the surface. Then they stick the tower stuff on top and bolt it down using the foundation bar/bolts.

The reason no one gives a poo poo about the OHSA is because their fines are pathetically low. It's a similar issue over here with the HSE but over here at least the HSE can obtain a court order mandating those changes or you face jail time for it. Like seriously I think 3 people died in a corn silo accident in the states like a year ago and the OHSA went "We're issuing our MAXIMUM FINE for this grave occurance, 10000 dollars per instance or 30000 dollars for 3 corpses."

Train crossings are basically evidence to me that right wingers are wrong about people being smart enough to make their own choices and don't need government help.

I'm assuming that it's balanced on the hydraulic arm so if nothing else it's not going to unexpectedly fall on him unless he does something stupid like disconnect all the hydraulics so the arm has no strength in it.

DemonToadGoat posted:The shape and metal of the arm give it strength, its not an inflatable tube, this guy is like 100% safe. Slow bleeds only happen if the arm is suspended and even then in cataclysmic failure the arm wont descend faster than the oil moves anyway so you've got a good 15 minutes to get out of the way. Until he removes the engine and the center of mass changes and it falls on him. Check and MATE. (but also yeah this is pretty much true, if theres enough weight on the arm to force the oil out if he disconnects the hydraulics it means it's going to fall away from him anyway).

Anyone post the PEPCON explosion yet? https://www.youtube.com/watch?v=VRyfMM2FTlk Long story short: this is the plant that made the solid rocket fuel for the space shuttle SRBs. When the shuttles were grounded, this plant was still contracted to make the drat stuff but had no where to put it or use it, so they started questionably started storing it in drums in what basically amounted to a shed on the yard, rather than any of the normal storage options (think firework storage bunkers). Then it caught fire due to some unprotected welding work, followed by a huge explosion that levelled the site.

I had a course on ATEX approval and suchlike yesterday, and that was full of lovely anecdotes of why safety critical applications need poo poo that can't be tampered with. The one the guy mentioned was that a huge oil fire we had in the UK in (the buncefield fire) happened because the maintainance team disabled the "high tank" alarm and then disabled the actual mechanism inside the tank for reasons that were unknown. The end result was that a remote oil refinery filled the tank remotely past the top and put like a foot of petrol on the floor of the entire depot site before it finally caught fire.

It must be significantly denser because it didn't explode, so the mixed layer between the air and the fuel is pretty tiny.

Planes are absurdly safe to the point that if a plane crashes it's almost universally pilot or crew error over actual mechanical failure. And that's why never fly by any budget Asian airlines because their pilots are not particularly well trained and the planes are not particularly well maintained. Same with Russian airlines.

Hilariously, Juche air is banned from all European airspace except for their latest planes (russian Tu-204s, lol) because they're the only planes that meet the safety standards of "not likely to crash into a town on takeoff". If you want to fly by a good airline, fly Singapore airlines. Their planes are excellently maintained, their pilots know their poo poo and they've been rated in the top 5 airlines for like the last 20 years. Also, they'll give you all the free booze you ask for on international flights provided you don't look drunk so if you can't sleep on planes because of your jet phobia just get hammered and pass out

GotLag posted:No need to wonder, this is what happens: Apparantly it was taking military cargo (I'm assuming vehicles or tanks or something) and they weren't secured properly and when it took off they all shifted to the back and absolutely hosed the hydraulics on the plane up as well as the trim, rendering it completely uncontrollable. Secure your loads!!!

Re: "Safety Plane": Planes are already 17 times safer than cars are. You are more likely to be killed in a road traffic accident on the way to the airport then you are on the plane itself. Those things are checked really routinely and thouroughly for the simple reason that people don't trust them. All a system like that would do is make maintenance more of a loving ball ache, as well as making it so the planes have to weigh twice as much and carry twice as much fuel because they can't be an effecient air-frame design any more, you have to use 2 god drat airframes inside each other. The entire system is a completely useless crock of poo poo.
