Which sequence correctly completes OSHA's re-energizing steps after lockout/tagout?

• A. Clear the machine, remove employees, remove LOTO device, test after isolating
• B. Remove LOTO device first, then clear the machine
• C. Test the machine first, then clear the area
• D. Ignore isolation and energize immediately

Answer: (A)

Re-energizing after lockout/tagout must start with making sure the area is safe and clear of anyone who could be exposed to moving parts or energy. Only after you’ve confirmed there’s no one in the danger zone should you remove the lockout/tagout devices, and that removal should be done by the person who applied them. Once the devices are removed and the equipment is isolated no longer under lockout, power can be restored and the machine tested to confirm it’s operating correctly and that all safeguards are in place. This sequence prevents anyone from being injured by unexpected startup and ensures the energy controls truly protect workers. The other options break this safety order by removing devices before ensuring the area is clear, or by attempting a test without proper clearance or isolation.
