What are residual risks in RF systems associated with?

Residual risks in RF systems primarily refer to the potential dangers that remain even after all known and mitigated hazards have been addressed. In this context, high voltages and hot surfaces are particularly relevant to RF systems due to the nature of their operation.

RF systems often involve the transmission and reception of electromagnetic waves, which can generate significant heat and can operate at high voltages during their processes. These conditions can lead to electrical hazards, such as electric shocks, and thermal hazards, like burns, if proper safety measures are not followed.

Understanding these residual risks is critical for technicians as they relate to maintaining safety standards and ensuring that equipment functions correctly without posing undue risk to personnel. Factors such as low frequencies, moisture levels, or the properties of materials (like insulation) can also present risks, but high voltages and hot surfaces are directly tied to the operational characteristics of RF systems, making this choice the most applicable in this scenario.
