When you see an RF (Radio Frequency) warning sign, it indicates that the area may expose individuals to levels of electromagnetic radiation that could cause harm. The correct action in this scenario is to leave the area or restrict access to it. This is vital for ensuring personal safety and compliance with safety regulations related to RF exposure.

RF radiation can have significant health effects, including the potential for tissue heating and other biological impacts, especially with prolonged exposure. As such, recognizing and reacting appropriately to these warning signs is an essential part of workplace safety protocols in environments where RF energy is present.

In contrast, staying within the area, proceeding with caution, or ignoring the sign are not safe practices and could lead to unnecessary exposure to harmful radiation. Such actions disregard the alert provided by the RF warning sign, which is designed to inform individuals of potential dangers. Responsible adherence to these warnings helps maintain a safe work environment.
