504 EM 385-1-1 Sections 27-34

27.H Residential Construction.

Wood used for temporary work platforms and/ or fall protection must be inspected for compliance with Sections 21 and 22, as structural lumber from the site may not meet the requirements for protective systems.

27.H.02 Hand and power tools must be equipped and used in accordance with the requirements of Section 13.

27.H.03 Raising Walls.

1. Before manually raising framed walls that are 10 ft (3 m) or more in height, temporary restraints such as cleats on the foundation/floor system or straps on the wall bottom plate must be installed to prevent inadvertent horizontal sliding or uplift of the framed wall bottom plate.
2. Anchor bolts alone must not be used for blocking or bracing when raising framed walls 10 ft (3 m) or more in height.

27.H.05 Truss Support Plate.

Where a truss support plate is used during the installation of trusses, it must be constructed of a 2-in x 6-in (5 cm x 15.2 cm) plank laid flat, secured linearly to a 2-in x 6-in plank laid on edge, supported with 2-in x 4-in (5.4 x 10.2 cm) wood members (legs) spaced no more than 6 ft (1.8 m) on center and attached to diagonal bracing adequately secured to support its intended load. All material dimensions are minimum and nominal.

27.H.06 Trusses installed without a ridge beam or other horizontal structural connection must be connected temporarily to each other and to a secured end gable by a minimum of one 1-in x 4-in (2.5 cm x 10.2 cm) plank face-nailed to every rafter on each slope of the truss. The number of planks must be sufficient to protect against wind-related collapse of the truss rows.

27.H.07 During construction, proper work platforms such as scaffolds and decks, in accordance with Section 22 must be used. Walking on plates, beams, joists, and other members more than 6 ft (1.8 m) above the ground or floor is prohibited unless workers meet the fall protection practices outlined in Section 21.
