<p>A fall safety barrier for use around a hole has anchor means removably secured adjacent a perimeter of the hole, first collapsible barrier means pivotally mounted about a first pivot location of the anchor means, and second collapsible barrier means pivotally mounted about a second pivot location of the anchor means opposite the first location. There are means for allowing the first collapsible barrier means to pivot between a first contracted position, where it lays upon the second collapsible barrier means, and a first expanded position, where it is upright and forms a first side of the fall safety barrier. There are also means for allowing the second collapsible barrier means to pivot between a second contracted position, where it lays adjacent the anchor means, and a second expanded position, where it is upright and forms a second side of the fall safety barrier opposite the first side. First linking barrier means are located between adjacent first ends of the first and second collapsible barrier means and form a third side of the fall safety barrier. Second linking barrier means are located between adjacent second ends of the first and second collapsible barrier means and form a fourth side of the fall safety barrier opposite the third side.</p> |
