Fire Rescue/Evac equipment
|
First things first: I am not a climber,or know much about climbing I am trying to learn the basics right now. |

The users of this system will have ZERO experience with climbing and will be under stress evacuating from the fire
This has bad idea written all over it. |
|
If the person using this system has zero experience with this sort of thing and is under stress, then that person is almost certainly going to make a mistake in using the backup rope system, and is going to end up stuck half way down unable to get to the ground. Sure, there's a chance that they will slip and fall using the drop ladder, but that's better than being tied to the side of a burning building, IMHO. |

Don't complicate the process. The only thing remotely idiot-proof would be the kind of autobelay found in a climbing gym setting, which is WAAAY outside your budget. Even then, dealing with mounting it, putting on a harness, and correctly attaching it in addition to dealing with the ladder thing... |
|
I agree with the above - The added complexity will likely add more risk than it mitigates. The chances are the system will be miss-used in a high stress situation. |

Thank you for comments, does the prusic needs constant fiddling with,while going down? It was my understanding that it locks up if there is a fall,but otherwise just slides with u? |

" What you suggest is hardly idiot proof and inappropriate for the same reasons others nixed the original idea. |

My question involved a very limited use of rope just as a backup device,and not for general rappelling. |

A prusik bights onto the rope when force is placed on the loop extending from it. It needs to be moved by pushing the hitch along the rope while the loop is unweighted. If it becomes weighted, the hitch should tighten around the rope*. It can be tough to get it to slide again after the load is removed.

trampoline at the bottom? |

The autobelay setup would be expensive and it requires a climbing harness, but on the plus side, you wouldn't really need the ladder--just clip in and jump off the balcony, if you trust that you set it up right. I don't think this is really a serious option, though. I've seen one of those setups drop someone about ten feet before suddenly locking up in a very hard catch. It turned out something was adjusted wrong and it was easily fixed, but I still avoid those systems. |

just saw this on another site. It might be what you are looking for |

Probably find a waist only harness that would clip around a person and auto tighten also. Remember leg straps are not really needed on a harness so you can remove them to make it easier to put on in a rush but trying to double back the waist clip would end badly for someone in a panic that didn't know what they were doing. Nice part of auto belay type device is that the person can't screw up lowering themself if they are clipped in and it would auto return to the top if you needed more than one person to get out. As others have said 25ft just use the ladder, even if you fall off the ladder there is a good chance you would live. You would be surprised how often people fall from 30+ ft with only minor injuries. I know multi people who have fallen from 80+ ft and lived. |

and you're going to be responsible for the liability of anyone who uses this? |
