During program removal, what should be done with red markings?

• A. Remove the red markings and re-label with black.
• B. Leave red markings in place.
• C. Replace red with blue markings.
• D. Cover red markings with black marking tape.

Answer: (D)

Red markings show an active warning or a status that needs attention. When a program is removed, that status must be neutralized so others don’t misinterpret the item as still in a restricted or active state. Covering the red markings with black marking tape accomplishes this cleanly: it hides the old signal and clearly indicates the item has been processed out of service, using a neutral, standardized color to signal deactivation. This approach avoids implying a continued warning (which red would convey) and prevents confusion that might come from applying a different color like blue. It also preserves a visible record of the change by masking the old indicator without removing the original mark entirely.
