To eliminate any hazard to people not involved in the roof framing work, the crew marks out a controlled access zone.Tthe crew foreman, as the designated “competent person” for the site, decides who is or is not permitted to enter this marked-off area.
So that work progresses both safely and efficiently, each crew member is assigned a specific task and workstation in accordancewith the company’s safety plan for truss framing. A worker on the ground is assigned the task of hooking trusses up to the crane spreader bar.
Another groundlevel worker prepares spacers and bracing material (C) and keeps the other carpenters supplied with nails and anything else they need.
At midlevel, a carpenter is assigned to each wall plate, working from outrigger staging set up on the outside walls or from rolling pipe staging on the deck.
Also at midlevel, in the center of the truss span, a carpenter works from the rolling staging, installing spacers and bracing on the lower truss chords and helping to pass material to the carpenters assigned to work at the top of the trusses.
