SafetyQuestion 660 of 700
A single portable ladder is used repeatedly to access an upper landing. Which combination of practices BEST reduces the risk of the ladder shifting or a worker falling?
a.Carry tools in both hands and climb quickly to spend less time on the ladder
b.Leave the base loose so the ladder can self-adjust, and slide down the rails to descend
c.Allow two workers on the ladder at once to pass materials
d.Secure the ladder at the top, block or tie the base against slipping, face the ladder, and keep three points of contact while climbing
Explanation
Correct: securing the top, stabilizing the base against sliding, facing the ladder, and maintaining three points of contact are the core safe-climbing practices. Climbing with full hands, sliding the rails, leaving the base loose, or putting two workers on one ladder all defeat stability and three-point contact and are unsafe.
