The _____ is responsible for ensuring hazards (electrical and mechanical) are removed or isolated before work can resume.

• A. Foreman
• B. Supervisor in charge
• C. Safety Officer
• D. Lead Person

Answer: (B)

The main concept here is who on the job site has the authority to confirm that all hazards are removed or isolated before work starts again. The supervisor in charge is the person who holds on-site responsibility to verify that everything has been de-energized and secured, and that the area is safe for work to resume. This role typically oversees lockout/tagout procedures, ensures electrical and mechanical energy sources are isolated, and signs off only when conditions are safe. They coordinate with crews, confirm that barriers or guards are in place, and communicate that it’s acceptable to restart.

Foremen and lead persons are important for daily supervision and guidance of the crew, but they aren’t the designated on-site authority to authorize a full restart after hazard removal. The safety officer focuses on safety programs, training, and compliance rather than the day-to-day authorization to resume work in a specific situation; they support the process but do not sign off on restarting the job.
