Form scaffolds and carpenters’ bracket scaffolds
Each bracket, except those for wooden bracket-form scaffolds, shall be attached to the supporting formwork or structure by means of one or more of the following: nails; a metal stud attachment device; welding; hooking over a secured structural supporting member, with the form wales either bolted to the form or secured by snap ties or tie bolts extending through the form and securely anchored; or, for carpenters’ bracket scaffolds only, by a bolt extending through to the opposite side of the structure’s wall.
Wooden bracket-form scaffolds shall be an integral part of the form panel.
Folding type metal brackets, when extended for use, shall be either bolted or secured with a locking-type pin.
