At what trench depth is proper shoring required?

At what trench depth is proper shoring required?

• A. 5 ft
• B. 3 ft
• C. 10 ft
• D. 15 ft

Answer: (A)

The main idea is the safety rule that trench protection is required when the trench is five feet deep or deeper. That five-foot threshold is the point at which a protective system, such as shoring, shielding, or sloping, must be in place to prevent a cave-in and protect workers. If the trench is shallower than five feet, protection isn’t universally mandated, though unstable soil or other hazards can still necessitate protection. Since the depth in question is five feet, proper shoring is required. The other depths don’t establish the triggering point, though at ten or fifteen feet protection would certainly be necessary as well; the key is that the requirement begins at five feet.
