Question 63 QMED04 - Boiler Technician-Watertender

The Correct Answer is B **Explanation for Option B (Red):** In standard industrial safety practices, particularly those governed by OSHA (Occupational Safety and and Health Administration) in the United States, and similar standards globally for Lockout/Tagout (LOTO) procedures, tags designated as "DANGER" tags are universally identified by the color **Red**. The primary purpose of these tags is to clearly and visibly warn that equipment is out of service, should not be operated, and a hazardous energy source has been controlled (locked out) to prevent injury or equipment damage during maintenance or repair. Red signifies imminent hazard and prohibition. **Explanation for Incorrect Options:** * **A) Orange:** While orange is used in safety identification, such as for warning against hazards that could result in serious injury (e.g., machine guards), it is typically associated with "Warning" or "Caution" signs related to physical hazards, but it is not the standard color for the primary LOTO "DANGER" tag. * **C) Yellow:** Yellow is the standard color for "Caution" in safety identification. Caution signs/tags warn against potential hazards that could result in minor or moderate injury. It is also sometimes used for maintenance or informational tags, such as "Out of Service," but it is not the designated color for the critical "DANGER" tag used in LOTO. * **D) Green:** Green is the color typically associated with safety information, safety equipment locations (like first aid stations or eyewash stations), and indicating safe conditions or the proper path to follow. It has no association with indicating a hazardous, locked-out condition requiring a DANGER tag.
