As nut and LB say, fix it down to the ground and it will be fine. If you surround it with temporary fence panels, there's a good chance those will be blown onto it and shatter the glass. Toughened glass is indeed tough and is heavy enough to not be easily blown out of the frame, which is where the danger lies. Once a pane is lost, the wind gets in and can blow more panes out. If the glass is fixed in with spring clips (usually 4 per pane), invest in some extra ones so you have 6 or more per pane.
