If a hazard can harm personnel or equipment, what type of tag must be used?

• A. Caution (Yellow)
• B. Warning (Orange)
• C. Danger (Red)
• D. Notice (Blue)

Answer: (C)

Danger tags are used for hazards that could cause death or serious injury to people, or could seriously affect equipment. They signal an imminent risk and require immediate action to remove the hazard or stop work until it’s controlled. This is why it’s the best choice when a hazard can harm personnel or equipment. In contrast, orange warnings indicate serious but not imminent harm, yellow cautions cover minor injuries or near-miss risks, and blue notices are informational and don’t denote a safety hazard.
