SafetyCâu 651 / 700
Workers need to reach a scaffold platform 9 feet above the base. Which access method is required under Cal/OSHA?
a.A ladder, stair tower, ramp, or equivalent access must be provided; climbing the cross-bracing is prohibited
b.Workers may climb the diagonal cross-braces since they are part of the frame
c.Any worker may free-climb the end frames if under 20 feet
d.Access is only required for platforms above 20 feet
Giải thích
Correct: safe access such as a ladder, stair tower, ramp, or built-in frame access must be provided when a platform is more than about 2 feet above or below a point of access; climbing cross-braces is expressly prohibited because they are not designed as a ladder. Free-climbing end frames and the 20-foot thresholds are incorrect; access is required well below 20 feet.
