Which color is associated with flammability on hazard labels?

The color red is associated with flammability on hazard labels because it signifies immediate danger and represents the need for heightened caution due to fire hazards. In the context of hazard classifications, red is universally recognized as the color that indicates substances that pose fire risks, allowing first responders and others to quickly identify potential threats.
