What color does ANSI standard Z53.1 specify to signify danger?

1. Yellow

2. Blue

3. Red

4. Green

The correct answer is: Red

The ANSI standard Z53.1 designates the color red to signify danger. This designation is rooted in the psychological association of red with warning and alertness, making it an effective choice for conveying serious hazards that could result in injury or damage. The use of red in safety signage alerts individuals to immediate hazards that require attention and caution. This standardization helps ensure uniformity across various industries and settings, enhancing safety communication and understanding. In contrast, yellow typically indicates caution, blue is generally used for information or mandatory actions, and green often signals safety or indicates a safe condition. Each of these colors communicates different levels of risk or action, but red specifically denotes danger, necessitating immediate awareness.
