Safety第 106 / 110 题
On a California jobsite, a trench 5 ft or deeper in which workers will enter also requires a specific state permit beyond federal rules. What is that requirement?
a.No permit is ever required in California
b.A Cal/OSHA excavation/trench permit for trenches 5 ft or deeper that workers enter
c.A federal permit only
d.A permit only above 20 ft
解析
Cal/OSHA requires a project or annual excavation permit for trenches 5 ft or more deep into which a person must descend, in addition to the cave-in protection rules. California often has requirements at least as strict as, and sometimes stricter than, federal OSHA. The competent person and daily inspections still apply.
