What does Out-of-calibration mean?

• A. Will not accurately indicate parameters
• B. A precautionary measure to give temporary special instructions
• C. Out-of-commission label
• D. Caution tag

Answer: (C)

When a tool is out of calibration, its readings can no longer be trusted because the calibration is off. The standard safety practice is to put a label indicating it is out of commission, so everyone knows not to use it until it’s recalibrated or repaired. This label clearly communicates the status and the required action: do not rely on the instrument now and have it serviced. While it’s true that the instrument won’t indicate parameters accurately, the most direct and practical way to prevent unsafe use is to mark it as out of commission. A generic caution tag doesn’t specifically convey calibration status, and describing it as a precautionary measure or simply out-of-commission without the explicit labeling would not convey the immediate action needed.
