ONE OF THESE EMPLOYEES TIED A 20-FOOT, 2-INCH SECTION OF NO. 4 REBAR TO A 12-FOOT SECTION OF NO. 5 REBAR. THE TWO SECTIONS OVERLAPPED BY ABOUT 1 FOOT, AND THEY WERE TIED TOGETHER WITH TWO PIECES OF NO. 16 AWG TIE WIRE. THE EMPLOYEE, WHO WAS STANDING ON THE GROUND, WAS HANDING THE JOINED SECTIONS TO A COWORKER STANDING ON A SCAFFOLD WHEN ONE OF THE TIE WIRES BROKE.
