Which color RF sign indicates an area where protective measures are required due to RF exposure exceeding MPE limits?

Explanation:
RF safety signs use color to communicate the level of hazard. Red signals danger and that protective measures are required because the exposure exceeds the maximum permissible exposure (MPE). In this context, the area is treated as a high-risk zone and access or actions needed to reduce exposure are enforced. Yellow would indicate caution about a potential hazard but not an immediate exceedance of MPE. Green typically denotes a safe condition, and blue is often used for mandatory actions rather than a hazard marker. So red is the color that communicates the need for protective measures when RF exposure surpasses MPE limits.
