Description
TECHNICAL FIELD OF INVENTION
15 The present invention relates to a railing and support device for use in the construction of residential and commercial buildings, and more particularly relates to a railing and support device to substantially protect a person from a fall during the construction or repair of a residential or commercial building.
BACKGROUND OF INVENTION
20 Working safely in the construction industry has become increasingly important. Increased fatality rates and injuries from workers falling from heights from a wall, roof, floor or slab of a building during construction or repair has resulted in both government and the private sector communities working together to reduce the risk of injury or fatality during such construction.
25 For example, fall prevention may be used to reduce the risk of injury or fatality during construction. Current fall protection systems in use instruction include, for example. Fall arrest devices, safety harnesses, various harnesses, lanyards and shock absorbers, scaffolding systems erected from the ground, and railing systems, have shortcomings, for example, scaffolding systems erected from the ground restrict access to work below the scaffolding, and are labour-30 intensive to install, particularly on un even terrain.
It is desirable to provide an easy and inexpensive way to install a device which may be used during construction to reduce or substantially eliminate the risk of injury or fatality associated with falling form a height during the construction or repair of a residential or commercial 35 building.
It is desirable to provide devices the components of which may be used interchangeably to reduce the cost of ownership, maintenance and handling.
