Which color indicates deficiency?

• A. Green
• B. Yellow
• C. Red
• D. Blue

Answer: (B)

Color-coding status indicators are used to communicate equipment condition at a glance in damage control. A deficiency means something isn’t working perfectly but isn’t a total failure, so it requires attention without being immediately dangerous. Yellow is used to flag these items because it signals caution and the need for follow-up or repair. Green typically means serviceable or ready, Red indicates inoperative or dangerous, and Blue often covers information or special status. So Yellow best represents a deficiency that must be corrected. For example, a valve that sticks intermittently or a minor leak would be marked Yellow to prompt maintenance work.
