SafetyQuestion 1348 of 1605
In California, the trench cave-in protection requirement mirrors federal OSHA, applying protective systems at depths of:
a.2 feet or more
b.20 feet or more only
c.10 feet or more only
d.5 feet or more (or shallower if a competent person identifies a cave-in hazard)

T8 §1541.1, like 1926.652, requires cave-in protection at 5 feet or more (and shallower when a competent person sees a hazard), unless the excavation is entirely in stable rock.
