Before entering a trench excavation, who must inspect the site?

• A. The Supervisor
• B. A Competent Person
• C. An Electrician
• D. A Safety Training Officer

Answer: (A)

The key requirement is that a competent person must inspect the trench site before anyone enters. A competent person is someone who can identify hazards and has the authority to correct unsafe conditions. The inspection checks soil conditions and stability, potential cave-ins, water accumulation, weather effects, nearby loads or vibrations, and that protective systems (shoring, sloping, or trench boxes) are in place and functioning. It also verifies safe access and egress (ladders, escapes) and that any required barriers or rescue equipment are ready. This inspection happens again if conditions change—like after heavy rain or a collapse. While a supervisor may oversee the work, the actual trench entry inspection is the responsibility of the competent person; roles such as electrician or safety training officer are not the designated inspectors for this task.
