Imagining fire escape devices, a slowly moving ladder would not be as fast as a
slide, but it would avoid a few perilous details of having a slide: People hitting each
other entering from different levels, going at different speeds, and the ejection of
people. A slowly rotating ladder (imagine
a tank tread, turned tall-ways) which
people could climb onto and just hold on to a particular wrung while the entire thing
slowly rotates downward on the outside. How to get them to let go at the bottom
(as certainly a great many will be stuck and unable to let go due to the shear shock
of the situation), I am thinking maybe shocking them, but then that might make
them hold on tighter. I would have a decent section that goes horizontal so that if a
person is holding on, the would be in a lying-down position, and more prone to
letting go.

If it were shear shock, I'd worry about their fingers. |

Just have a rubber "scraper blade " above an angled, padded chute
that deflects the rider off to the side. |
|
| |
This is basically an "outside " version of a paternoster lift. |
|
| |
Use metal rungs, with electrical contacts at the bottom of the ladder to
deliver a shock to anyone who holds on for too long. |
|
| |
(Don't use DC - they might not be able to let go.) |

What if they're paralyzed, infirm, or just too wimpy to hang
on? |

Natural selection happens, RayfordSteele, Natural selection. |

And as for how to tell them to get off.. I think some lights and a
recording would do fine. |
|
| |
And so they fall off, taking out half of everybody below
them. |

Anemone-like sticky suckers ? Blood to your head is relaxing under panic. |

If the device is inclined at 70° to the horizontal, users can effectively lie on the slowly descending upper surface. Handles will be useful, but are probably more for reassurance than utility. |
|
| |
When the user reaches its lowest point, gravity will encourage them to descend the short distance onto an inflated crash mat. Those inclined to hang on will find themselves hanging from an inverted surface, and can be safely removed by a low-pressure high-volume water jet. |

This sounds like something between a man engine and a
paternoster [links]. |
|
| |
Fine until a pinion shaft fractures. After that, not so much. |
|
| |
I found something even closer: the belt manlift! [link] |
|

Unfortunately, this means that the women and children will
still have to be rescued by traditional means, and the men
will have to wait for that to be done before escaping more
rapidly, so it won't help that much. |
