Lockout and tagout devices are used to _____.

• A. Protect workers from all possible sources of energy
• B. Control noise
• C. Provide ventilation
• D. Improve lighting

Answer: (A)

Lockout and tagout devices are used to prevent the release or unexpected energizing of equipment while someone is working on it. The essential idea is to isolate all energy sources—electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or gravitational—and keep them from powering the equipment until the work is finished. A lock physically ensures the energy-isolating device can’t be turned back on, while a tag provides a warning and identifies who placed it. This protects workers from injuries that could happen if the machine starts up or if stored energy is released during maintenance. It isn’t about controlling noise, providing ventilation, or improving lighting, which is why those options don’t fit.
