HI-RISE FIRE ESCAPE
The foundation of escape from a fire is, “as quickly as possible”/ simple as that. The subsequent reality however is, once the path of escape has been closed: there are no other options, except “jump or someone else must assist”.
I think it is twelve floors, that the biggest fire escape ladder can extend: there are not many of these. That ladder can only accommodate a very few people at a time, and they must not error in their own footing: which means it ultimately has very little value/ because the truck it is mounted on requires a very substantial footing as well.
So other than retrofitting internal elevators for fire escape by protecting them from fire/ and pressurizing them so the fire itself can be kept out of the elevator passageway (even more): you must go outside.
The immediate need is: for people carriers that can be operated safely/ built cheaply/ and are available in a short amount of time.
The structural element required for such a lift system is simple: EXTEND A SUITABLE I-BEAM or other from the roof/ over the edge of the building to the right length. Then attach a cable to that escape structure, bring it back to the building wall/ enclose it for rust protection in an escape housing when sufficient force is applied. At the bottom a very simple platform with guardrail, along with a common cable winch; hooked to that cable from the roof; and you have a people escape carrier.
The escape structure located on each corner of the building allows for a “corner rap carrier” which will maintain a reasonable wind control. Alternately if the building is big enough: two I-beams mounted onto the wall, will provide stability for the carrier on its ascent or descent. A gas engine to operate the winch with battery backup: it can be remote controlled from the ground. The carrier itself should have “stake pockets” for the insertion of asbestos panels covered in aluminum (only the dust is hazardous). Because a building can erupt in flame as you are going up or down: this gives you time.
The operational winch should be onsite and carried with the fire department. When you get to the floor you need to be at: a small explosion will open the wall. You will then insert a megaphone, and pipe in clear un-mistakable: this is the fire department searching for you/ COME QUICKLY. A bigger hole can be blasted if needed. The building should contain signs on the wall indicating in an emergency this is where the fire department will blast an opening. Preferably inside and outside as is the use of a pipe.
The blasting method is simple. Insert a steel rod, attached to the blast containment cover with the explosive inside into the wall pipe. A suitable retention system should already be in place. Such as “spider legs” attached to the piping that goes through the wall to distribute force; and a threaded nut to anchor in the blasting cover. It is then ignited, and a suitable hole is formed to start the evacuation. Other efforts can then be made. If it is a glass building, a pendulum anchor like device that is allowed to swing from the bottom of the carrier is used to break the glass from above.
The carriers can be and must be “a part of the landscape” with all parts necessary to complete the carrier close/ and simple to install. No need to be complicated, support cables are simply something to grab onto. The common “window washer” machines, for scaling high-rise buildings; are a suitable example. The difference is capacity/ and the escape carrier must include a sloped roof, so that people trying to jump onto it from above are thrown off/ so as not to jeopardize the rest.
It is valid and true: that in all potential fire traps, which include the three story house/ it would be best if, a cable escape existed in place. That would include a cable anchored into the roof/ or suitable place: which can be lowered down/ released/ or whatever it takes to provide a structural link to the ground. The harness required for the descent: should be given out only to those who “take the course (get a license)” about what to do, how to do it, and especially what not to do. Hi-rise buildings can also offer this. a reality which can include if you have an anchor point inside the window of escape/ then you can in fact, “even bring your own cable and harness”. Those who repel know how; but with small steel cables, the reality is one time mechanisms which aid braking and descent should be used.
