An toànCâu 448 / 521
In a trench 4 feet or more deep, a stairway, ladder, or ramp must be provided so that:
a.Workers can jump out if needed
b.Only one is provided per trench regardless of its length
c.It is optional as long as the trench is short
d.No worker has to travel more than 25 feet of lateral distance to reach a means of exit
Giải thích
Trenches 4 feet or deeper require a ladder, stairway, or ramp located so that lateral travel to a means of exit is no more than 25 feet. Expecting workers to jump out, allowing only one regardless of length, or making it optional does not meet the egress requirement for deep trenches.
