What color is an out-of-calibration label?

An out-of-calibration label is typically orange to signal that a specific piece of equipment or instrument is not within its specified calibration range and should not be used until corrected. The orange color acts as a clear visual alert, distinguishing it from operational equipment. The use of this color is standardized in many organizations because it stands out, immediately drawing attention to the issue and ensuring that personnel are aware that the equipment may produce inaccurate results. This helps to prevent any potential errors in operations that could arise from relying on improperly calibrated instruments.
