"Escape Parachutes are a way to escape for tenants in high-rise office buildings, apartments and hotels. This device is solely intended as a "last resort" escape in the event of a natural or man made disaster. It is used in exiting a structure when normal methods of escape are blocked and no other alternative exists. Although these are not risk free devices, they offer one last chance when no other options are available."
