    Hi!

    What are the saftey percautions on log flumes. Things like emergency procedures and what stops the logs in the event of an emergency stop?

    There's normally exits along side the ride and they stop the ride by hitting a switch or a button on the control panel.

    But what stops them? Does the water drain or do the water jets stop? Or do they have brake blocks like on roller coasters??

    The water propulsion system in the flume-way itself stops. The logs naturally stop moving forward when there is nothing propelling them.

    If they need to actually evac guests from the logs, CMs will come out and maneuver each log to the nearest "land" so guests can step out. There are places all along the flume where logs pass within stepping distance of land.

    If they're going up a lift, they stop on the lift and hold in place. If you evac, you are assisted out by a CM and walk down the stairs that are alongside every lift.

    If you're going down a drop, the log just finishes the fall and will stop when it loses momentum in the runout area, or when it gently bumps into another log that's been holding in the next block.

    Not like a coaster where they have "brake" sections, per se.

    Thanks!
    I saw a video of splash mountain and they recorded the ride looking backwards so you could see behind the boats and I noticed these little gates in the water and closed qhen the boat went through, youtube splash mountain backwards, its the first video and its by themeparkHD. Skip to 4:58 and you can see the gates close. I was wondering if these were to stop boats getting too close to eachother

    Many log flumes do have brakes. You can see them, they push against the sides of the boat and hold it against the current.

    Many log flume rides run on a block system, a log can't continue until the log has completed the drop.
    If a ride were to malfunction, the blocks would prevent the logs from continuing, and the Jets would stop.
    On Lifts they all have anti-rollbacks if the lift were to stop.

    In May 2015 we were on Splash Mountain and the ride stopped. We sat there for about 2 minutes, thinking we would start back up, but then the music stopped and all of the lights came on. An announcement informed us that the ride was having technical problems, and we would all be evacuated, and to remain in our seat until a CM came to escort us out. We were about three logs from going down one of the smaller drops. After about 10 minutes (which seemed like 30) about 5 CMs appeared and had to unlock the restraining bar in our log with a large tool. We stepped out of the log, and had to wait along side the wall until all of the riders in our "area" were out of their logs, and then they walked us about 30 feet to a door that opened to the outside. We walked down about 2 or 3 flights of metal stairs behind the ride, and ended up in the maintenance/back stage area behind the ride. There were current and old floats back there, and a large shelf with spare parts for some of the rides. It was kind of a scary experience when it was happening, but was interesting to see the ride with the lights on, and to see the back of the park. We all got free paper fast passes to use on any ride for our inconvenience. Now every time my kids and I go on the ride, we hold our breath when we get to the part where we were stuck, hoping we make it through.

    Most of the ones I've seen push up from the bottom. I have see the side-gates, though.

    Many log flumes are gravity fed. The lift hill is "dry" and there's a pipe that goes to the top to have water cascade down the drop side. That's mostly for show, though. You're going down the hill on the wheels on the bottom of your boat and tracks just to the side instead of down some water plume. If you look, there's typically a basin underneath the drop hill where a lot of water is being pumped in (huge pipe and pump). This fills up the splash zone where you touchdown which, again, is mostly done with the wheel and tracks up to the very end of the splash. It keeps you straight and safe in the process. At that point, traditional log flumes will be gravity based until the next lift hill or station. There may be some jets in flumes like Splash Mountain to keep you going.

    With regards to safety:
    - There are brakes in the station and sometimes they use gates. I think Splash Mountain uses gates, if I remember.
    - They have the rubber conveyor belts there that lift you out of the water at Splash Mountain and provide a stable surface for loading and unloading whereas traditional log flumes would have the underneath-brake which is a set of wood/metal planks with rubber padding. They push those up enough to where it either catches the boat or stops it and you load/unload.
    - Other than that, as mentioned before, if you need to emergency stop then you just stop the lift hill and stop any action in the loading/unloading area. Everyone else just floats forward until they bump into the log in front of them.
    - You want to keep the trough full, though, as you can have a nasty accident if a log is coming down the drop and there's no water there to slow it down and float it at the end of the aforementioned track. There was a case like this at Six Flags Over Georgia, years back, that really hurt someone and resulted in a lawsuit.
    - If you look at the logs, themselves, then you'll see that they have wheels on the bottom of the boat (and I've never been a fan of partially empty troughs where you're just rolling on the bottom) and along the sides of the boat, but still on the bottom, to keep you floating along in the trough.

    Other than that it's pretty much: Guests stay in the boats unless told to by employees. There's not much else to them. I think the water is about knee deep in most of them so you'd have to be trying to drown. A bigger issue would be if you got out of the boat and then were in the path of the other boats. The boats themselves are pretty heavy and if you add a fully loaded boat then that's a lot of mass coming at you that is going to use you to stop. I bet you'd be seriously injured or killed in that situation. I've never seen anyone get out of a boat on a log flume nor heard of it. Overall they're pretty safe rides. You really just need the pumps working.

    With that said, you're probably thinking of a power outage and what happens if that pump isn't filling the trough that you land in from the drop: It's true that it will drain out but it won't be immediate so if someone was at the top of the drop and coming down and there was a power failure just as they crested, there'd still be plenty of water for them at the bottom. I'd also guess that there's some kind of mechanism or procedure in such events so that when the power comes back on it waits for the trough to fill before starting the lift hill back up.

    There was essentially just such an accident on Splash Mountain a few years back (which may or may not have led to the addition of the lap bars in the logs) that led to the death of a passenger. There was some kind of a brief ride stoppage with a few logs backed up in the Bee Cave. The man got out of his log on the left side walkway. He then tried to climb over the back of a log that was at the normal hold-point at the top of the drop into the Laughing Place when the ride system advanced it into the drop. He fell into the water behind the log and was pinned by the next log in line.

    (And of note to anyone skittish about the safety of rides, this specifically happened because the guest did *not* follow instructions to stay seated in the log at all times...)

    Sorry to bring this old thing up again, but I saw this and was legitimately curious what would happen if you were going down the big drop (or any drop for that matter) but there needed to be an emergency stop? Is there some way to prevent this or do you just have to go down the drop first before a proper E-stop can happen?
    Edit: nvm. I think this was already answered and I just didn't see it. If not and I'm just going crazy, I'mstill open to explaination to this lol.

    Like with a roller coaster, you have to keep going down. The ride track is broken down into segments known as 'blocks' and only one vehicle is ever allowed in a block. Access to the blocks is controlled through brakes and lift mechanisms. So no matter if you are on a drop or just one of the indoor scenes, you will not stop until you reach the next block brake.
