Extension Ladder Footing Operations Those shopping for for the primary time without the advantage of fairness rises in an existing domestic, face a double-whammy of document. Never use a self-helping ladder in the closed role. When unavoidable obstructions are encountered, the minimum perpendicular clearance between the centerline of fixed ladder rungs, cleats, and steps, and the obstruction on the climbing side of the ladder may be reduced to 24 inches (61 cm), provided that a deflection device is installed to guide employees around the obstruction. That may be the easiest way to treat it. For an overhead load exposure, riggers must _____________, if operator cannot. See Astroid, where you will see your $\frac23$.). Note: Standard A14.10 has been incorporated in A14.22007 and A14.52007. Failure to disconnect from power source (10%) Administrative Controls.
