The device, Escape, with a simple structure, assures users that they will survive drops from up to 200-meters (60-storey) building. Mr. Hai said Escape allows for a smooth descent from tall office buildings and can carry five people steadily from skyscraper heights via a secure length of cord.
In addition, the special device is cheaper than other available equipment. For instance, a pulley costs VND10million but can rescue only one or two persons per trip, air-beds cost VND300 million but are not safe for the elderly or pregnant women, while Escape fetches just over VND260,000 but can rescue five persons at once from endangered high-rises.
