Which color is used for RF notice signs?

Explanation:
Blue is used for RF notice signs because blue is the color chosen for informational notices in standard safety sign color coding. This conveys information about RF energy or required procedures rather than an immediate hazard. Red signals danger, yellow warns of potential hazards, and green marks safe conditions, so they don’t fit the purpose of a notice. A blue RF notice sign communicates information such as “RF energy present” or “RF exposure limits apply” and tells workers what they should know or do without implying an immediate danger.
