Russian designs airbag for skyscraper staff

Russian scientists have invented a wearable airbag designed for use by staff in skyscrapers and other tall structures.

The inventors said the device fits into a backpack and gives a good chance of survival at any height.

Users must fall backwards from the building and then the airbag inflates and a series of air-filled layers absorb the shock of impact.

Scientists from the Babakin Research Centre in Moscow said the airbag works equally well from the first or the 51st floors.

It weighs 44 pounds, the outer skin is fireproof and it is expected to cost between $100 and $250.
