What is the proper labeling practice for hazardous energy sources on a ride?

• A. Use highly visible tags, follow lockout and tagout procedures, and ensure tags remain legible until the issue is resolved.
• B. Post a general safety notice at the ride entrance after maintenance is complete.
• C. Rely on audible alarms without visual tagging for energy sources.
• D. Remove all labels to simplify operation.

Answer: (A)

Ensuring safe maintenance on rides relies on controlling hazardous energy sources through clear, persistent labeling and strict lockout/tagout practices. Using highly visible tags communicates that a piece of equipment is isolated and cannot be energized until the tag is removed, which helps anyone coming into contact with the system understand that work is in progress. Lockout and tagout procedures provide a formal, reversible process to physically isolate energy sources — electrical, hydraulic, pneumatic, mechanical, thermal, and others — so that unexpected energization cannot occur while maintenance or adjustments are being performed. Keeping the tags legible and in place until the issue is resolved ensures continuous hazard communication throughout the entire repair process, protecting workers and riders.

General notices at the ride entrance don’t specifically address the energy isolation of individual components and don’t prevent accidental energization. Relying on audible alarms alone misses the critical visual warning that someone is working on a specific energy source. Removing labels eliminates hazard communication entirely, increasing the risk of accidental startup or energization.
