In a lockout/tagout procedure, who installs lockout/tagout devices?

• A. Only supervisor
• B. Every employee involved in the work
• C. Safety officer
• D. Manufacturer

Answer: (B)

Lockout/tagout relies on personal control of the energy isolation. Each worker involved in the task must apply their own lockout/tagout device to the energy‑isolating point so that no one can re‑energize the equipment while work is in progress. When multiple people are working, every individual places and keeps their own device, and the system stays isolated until all devices are removed by the people who placed them. This is why the correct choice is that every employee involved installs their own lockout/tagout device. Supervisors, safety officers, or manufacturers don’t install devices for each worker in the field; the devices are installed and removed by the authorized workers performing the work.
