What does a blue RF notice sign indicate?

A blue RF notice sign indicates that RF exposure levels may exceed the General Population Maximum Permissible Exposure (MPE) limit but will remain below the Occupational MPE limit. This sign serves as an important safety reminder for individuals who may enter the area. It informs them that while exposure levels could be higher than what is considered safe for general public access, the levels are still managed to ensure that they do not reach the thresholds determined to pose risks to occupational workers, who may be exposed under controlled conditions.

Understanding this classification is crucial for telecommunications technicians and workers in the field, as it defines the safety protocols and required personal protective measures they must adopt when working near such RF emissions. It is important for them to recognize the difference between general and occupational limits, as it directly impacts how they prepare for potential exposure while ensuring they maintain safety standards to protect both themselves and the general public.
