What is the primary purpose of tagging and isolating equipment during ALRE maintenance?

• A. To improve maintenance speed.
• B. To prevent accidental energization and document equipment state.
• C. To simplify scheduling.
• D. To satisfy random audits.

Answer: (B)

Tagging and isolating equipment during maintenance is all about safety and control of the energy state. By isolating the equipment from its energy sources and tagging it, you prevent accidental energization while work is being done. The tag communicates the status, who applied it, and why the equipment is offline, so anyone who might energize or operate it understands that it is under maintenance and must not be powered on until the tag is removed by the person who placed it and the work is verified complete. In ALRE, with high-energy systems like launch and recovery gear, this reduces the risk of serious injury or damage. While tagging can also aid accountability, the primary purpose is to keep people safe by ensuring the equipment remains in a known, non-operational state until it’s ready to be re-energized.
