Question 56 QMED05 - Machinist-Pump Technician

The Correct Answer is D **Why option D ("Red") is correct:** In standardized industrial safety procedures, particularly those governed by OSHA (Occupational Safety and Health Administration) standards for Lockout/Tagout (LOTO) procedures (29 CFR 1910.147), **Red** is the designated color for "DANGER" tags. These tags signify that the machine or equipment is tagged out of service, poses an immediate hazard if energized or operated, and must not be started or used under any circumstances. The color red is universally recognized in safety protocols to indicate immediate hazard, danger, or stop. **Why the other options are incorrect:** * **A) Yellow:** Yellow is commonly used for "CAUTION" tags, which warn against potential hazards or unsafe practices, but do not indicate an immediate, life-threatening danger associated with the LOTO procedure itself. It is also often used for warning/alert statuses. * **B) Green:** Green typically signifies safety, 'go' status, or operational status (e.g., safety equipment location, machine ready to run), and is never used to indicate a danger or lock-out condition. * **C) Orange:** Orange is usually associated with "WARNING" tags. While warning tags denote a higher severity than caution, they are generally reserved for hazards that could result in serious injury or death but are typically not used as the primary identifier for the absolute prohibition implied by a DANGER LOTO tag (which must be red).
