Which ink color is used to mark critical log entries on temperature and magazine logs?

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

Answer: (A)

Red ink is used to mark critical log entries because it provides a quick, unmistakable visual cue that something requires urgent attention. On temperature logs, readings that are outside safe ranges or show anomalies must be addressed promptly, and red highlights ensure the issue is noticed immediately. On magazine logs, conditions affecting safety—such as temperature or environmental factors that could impact ammunition storage—also get red to signal priority review and action. Using this color for urgent items helps crews respond faster and prevents overlooking dangerous or time-sensitive information. Routine entries are typically written in other colors, so the critical items don’t blend in.
