What color must fire alarm pull stations be?

Fire alarm pull stations must be red to ensure they are easily identifiable in an emergency situation. The color red has long been associated with fire safety and is universally recognized as a signal for alertness and danger, making it the standard choice for devices intended to activate fire alarm systems. This prominent color helps individuals quickly locate and use the pull station when immediate action is necessary, thereby contributing to effective emergency response and evacuation efforts.

The use of other colors like blue, yellow, or green could lead to confusion, as these colors are not commonly associated with fire alarm equipment. Their use could detract from the immediate recognition required during emergencies, potentially endangering lives. Hence, red is the color designated for fire alarm pull stations to maintain consistency and ensure public safety.
