Which color represents the general alarm?

The color that represents the general alarm is red. This is a widely accepted standard in safety and emergency response protocols. The color red is often associated with danger and alertness, making it an effective choice for signaling emergencies. It is used to catch immediate attention and convey urgency. In various contexts, red is used on stop signs, fire alarms, and emergency equipment, which reinforces its association with urgent situations.

Other colors have specific meanings in safety protocols: green typically indicates safety or 'all clear,' yellow serves as a warning to take caution, and blue is often used for informational or mandatory signals. However, red's strong connotation with emergencies and immediate action makes it the correct choice for representing the general alarm.
