According to OSHA, how much accumulated water is allowed to accumulate in an excavation before workers must stop?

• A. none, no accumulated water is allowed
• B. 1 inch measured to the edge of the hole
• C. 3 inches measured to the edge of the hole
• D. 6 inches measured to the center of the hole

Answer: (A)

The key idea is that standing water in an excavation creates serious hazards by weakening soil and increasing drowning risk, so OSHA requires keeping the trench dry. There should be no accumulated water in the excavation; if water begins to collect, work must stop and the water must be pumped out or drained until the trench is dry and safe to resume. This practice helps maintain soil stability and protects workers from cave-ins and drowning.
