The Verti-Scape Escape Chute
How it Works
Is manufactured from three completely separate and distinctly different fabric tubes/chutes.Each tube/chute has it's own function to perform, and it is only when these three tubes/chutes are assembled together do they then become an Escape Chute.
The Outer layer of the escape chute (Dark Grey) is there to protect the users from flame and radiated heat, it can withstand a constant temperature of between 550 & 600° C, and melts at around 810° CNote the gap between the outer layer and the middle/braking layer, this allows air to circulate between the two tubes, thus preventing heat transfer. The Middle/Braking layer (Light Gray) is the layer that makes the system work, it is an elsticated tube which is approximantely 300mm in diameter in it’s rested form, but has the capability to expand to 600mm as the evacuee travels through, as the evacuee applies outward pressure from within the chute, the evacuee slow down, as they release pressure they speed up, the evacuee has full control of the speed at which they descend. The inner/support chute (Beige) gives the system it's strength to hold the weight of the all chute users withgin the chute at any one time, this layer has loops stitched into the top, into which we insert a stainless steel rolled pipe. The pipe is then held in place by the deployment device, or into a recess set into the floor in the case of a multi-entry system.
To use the escape chute, the user sits on the edge at the entry point, with their feet and lower legs in the chute, at this point you will feel the escape chute grip your lower, legs, expand your legs against the chute, and you will feel considerable resistance.While supporting your body weight with your hands, lower your self into the chute, keeping your legs fully extended against the inside wall of the chute. Once your shoulders are into the chute, push your hands and arms against the wall of the chute, this action and the bending of your legs at the hips will bring you to a stop. By relaxing the pressure against the wall you will then descend.
Relax Pressure = SPEED UP. Increase Pressure = SLOW DOWN
By applying enough pressure you can come to a complete stop, and just sit there!The evacuee has full control of the speed at which they decend.
SINGLE ENTRY ESCAPE CHUTE
A Single-Entry Escape Chute means that there is only one entry point and one exit point, where as a Multi-Entry Escape Chute can be entered at various floor levels, but still has only one exit point.
Single Entry Systems are generally installed onto the roofs or through walls , windows and off balconies of buildings, and are deployed on the outside of the building.
Generally escape chutes deployed outside of the building have a height limit of around 120meters or 50 floors.
Typical is a roof mounted storage/deployment device, Model No 700 series similar to the systems seen below.
Multi-Entry Escape Chute
The vast majority of Vertical Escape Chute applications to date are described as a "Single Entry" system; this is where you have just one escape chute that has only one entry point.
But in the case of a Multi-Entry Systems, instead of the chute going from the roof to ground level as a one piece chute, we have chute equal to the height of each floor, where we insert a chute into the floor, this then sends the evacuee through to the floor below, and directly into the chute starting from the floor below, this is then repeated on all floors until ground level, or the designated exit point.
