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.

The answer to "Hey boss where do we store all this extra literal rocket fuel?" really shouldn't be "In a pile out back"

To be fair we did get a kickass video out of it.

I worked at Cedar Point for two summers! all my old coworkers on facebook are being catty as gently caress about this and rightfully so. Sadly enough, had he waited until the end of the evening an employee have retrieved his wallet and keys after the ride was shut down for the night.

Each night its a worker's job to walk the length of each coaster's track with tongs and a bucket to pick up all the stray crap dislodged by the ride. It all gets filed and turned in to lost and found by midnight, 1 am at the most if its one of those late nights and theres a long line of riders left.

Also Millennium Force is the best ride.

Plus I got to wear a hardhat whenever I went under the tower to pick poo poo up at the end of the night, so, OSHA

But the summer before I worked there the launch cable snapped, peppering the riders with metal shards and making one hell of a racket according to my coworkers.

those dented plates are magnetic fins that align snugly with slits under the train, slowing it down in case of roll back.

At Six Flags Great Adventure I had a fun time on the wait to pull into the station on Nitro looking at all the crap that had dropped off the side onto the net. At least half a dozen hats on my side, but also stuff like maps, water bottles, and a child's sock. This was the end of the ride where the trains would simply be sitting still before pulling back into the station to unload, so there's no way it just fell off during an inversion or something.

More coaster OSHA! The Hollywood Rip Ride Rockit at Universal Orlando is infamous for its troubles. It was often rumored to have opened a good half year early (this is including delays of several months; it was meant to open even earlier to end the spring season). It was built shoddily enough that it started out incredibly smooth but has gotten rougher on a yearly basis. There's been at least one incident that was kept out of the media (referred to as "Rockit Bumper Cars" among employees) where a train coasted through a brake run and collided with the one ahead of it. Relatively mild injuries, but obviously not a good thing or a normal occurrence.

A definite problem that the coaster had was with dropped items. They didn't install a net under the first loop, as it's non-inverting (it rolls over at the top so the riders don't go upside-down) and they figured minimal risk for stuff falling out. But a few elements later, after going through a building in the Twister queue, it goes up almost vertical and then sharply curves to the left and back down again. This motion had the effect of whipping items out of pockets and launching them in a ballistic arc, where they would land backstage with pretty high momentum. Until a vertical net was placed to deflect cell phones and wallets, Universal took the expediency of simply telling employees not to take a particular path while the coaster was running.

Of course, that didn't stop them from failing to install a net until quite recently over the "Crowd Surf", where the coaster travels over the queue and tilts sideways. I don't believe any injuries were caused, but phones that lasted until then were known to smash into empty parts of the queue; as with the curve before, the angle caused them to come out horizontally rather than merely falling under gravity and thus having all the speed applied by the coaster on the way down.

I remember a man once smuggled a golf ball onto the ride. He intended to let go at the apex of the track, probably like so

caution: turn your volume down
https://www.youtube.com/watch?v=VgFdvztZrIM

well he succeeded in letting go of the golf ball at the top but he lost control of it. The ball flew down and away into the unwitting crowd, bounced off the concrete and hit a pregnant woman. Ride operators at certain positions are instructed to watch each train launch for exactly this kind of poo poo, so we stopped his particular train, checked the on-ride photo for the golf ball (it was in his hand clear as day) and park police escorted him out of the park and likely to the real police station in Sandusky.

The pregnant woman was scared but fine. It hit her in the leg or butt or something.

The real trick isn't how far you run, but when you start running. At the Texas City BP disaster, most of the work crew got away because they gtfo before the ignition occurred. It was the consultants in portable buildings next to the blow down drum that saw most of the fatalities.

Potentially, drive home. Places that explode like that often have (what I assume are) insurance credits for making staff back into parking spots so nonessential personnel can drive away at maximum efficiency. None that useful for sudden unexpected explosions, more the sort of thing in case something is on fire that shouldn't be.

My uncle was working at Ford when his plant exploded (Might be this one: http://www.cnn.com/US/9902/01/ford.explosion.02/ I thought it was a year or two more recent but I could be mistaken. It would help if I knew which plant he was working at) and, having been involved in an industrial accident before, immediately dropped his poo poo and took off running and didn't look back until he was at the bar down the street. He got in a bunch of trouble for not calling my Aunt; instead letting her anxiously watch her husband's workplace burn down on the news while he was getting a drink.

That's not really a problem though? They probably needed a lot of gas for heat generations for chemical production processes. The only affect this had was their connection to the gas line was damaged in the explosion and created a burning flare afterwards, which is pretty contained and easily fixed.

I rode this clanky old coaster at Cedar Point. At the end we didn't exactly brake and zipped through the loading area, unlocking all the safety bars.
We rounded the bend then back up the chain lift before they stopped it and came up to manually relock the bars (got to go again!).
Those were just simple steel bars flipping loosely. It would have been a real challenge to stay in the car like that.

Yup! That's it. I think it's some kind of massive array of hydraulic motors. The whole system is pretty sophisticated - I guess it weighs the train before launching and calculates just the right amount of acceleration to apply so it can just make the top of the hill.

http://hydraulicspneumatics.com/200/TechZone/Accumulators/Article/False/9810/TechZone-Accumulators

It was neat to see the control systems for the park's rides. There were tons of safety things that people never see, like light curtains around the rides.

I am trying to remember if the park's power distribution system was 4160, 7200V, or some different voltage level.

Sounds like the Blue Streak. Second coaster I did at the park and it beats you up pretty good.

In fact, I've had the poo poo kicked out of me by every wooden coaster I've ridden except the Hersheypark Lighting Racer.
