An excavation is 6 feet deep and workers must climb in and out repeatedly. What egress does Cal/OSHA generally require?
a.A ladder, ramp, or stair located so that no worker travels more than about 25 feet laterally to reach it
b.One ladder anywhere on the whole job site
c.No egress is needed for excavations under 10 feet
d.Workers may simply be pulled out by hand
Giải thích
Cal/OSHA requires a safe means of egress, ladder, stairway, or ramp, in trench excavations 4 feet or more deep, located so a worker does not have to travel more than about 25 feet of lateral distance to reach it. Option a reflects this. A single ladder somewhere on site (b), assuming no egress under 10 feet (c), or hand-pulling workers (d) all fail the requirement and endanger workers during a cave-in.
