Which color indicates a full alarm?

Which color indicates a full alarm?

• A. Red flashing triangle
• B. Full red
• C. Flash blue
• D. Solid green

Answer: (B)

Status signaling uses color to communicate alert levels at a glance. A full alarm is the highest level of response, triggering the maximum deployment. In these schemes, red is reserved for emergencies, and a solid red signal specifically indicates the full alarm condition. The other options describe different states: a red flashing triangle is more like a warning or fault indicator, blue flashing suggests a control or non-emergency status, and solid green typically means ready or available rather than actively responding. So, the color that indicates a full alarm is solid red.
