Named,  The Spider Lifeline to Safety, this device hopes to help save lives in the case of a fire that has blocked all exit points. According to The Spider Lifeline to Safety website:

The Spider Lifeline to Safety can save lives when staircases
and fire exits have become impassable, or circumstances
such as disability make using conventional exits
impossible. It comes in to its own as a last resort and
can save your life.
The ground-breaking device employs fall-arrest
technology to lower people to safety down the exterior
of a building using a harness and strengthened steel
cable. The system allows users to descend at a regulated
speed ensuring a quick exit to safety, at a pace that does
not endanger the user or other people evacuating
the building.
Spider Lifeline to Safety is suitable for use in all buildings
providing safe exit from any height whether a two storey
house or a 50 storey office building. The device is capable
of multiple evacuations, with adults able to carry their

children and a fast return of the harness to the evacuation point for immediate re-use.
The Spider Lifeline to Safety has been designed to work in
all conditions and does not need any external power
source for operation. The Spider Lifeline to Safety has been

rigorously tested and also includes an emergency

braking system as well as a double security mechanism
