*Question G0A08:
[97.13(c)(2)] Which of the following steps must an amateur operator take to ensure compliance with RF safety regulations?*  

*Correct Answer is  C: Perform a routine RF exposure evaluation and prevent access to any identified high exposure areas*  

### AI Response: (may contain errors)  

To ensure compliance with RF safety regulations, amateur radio operators must:

1. **Perform a routine RF exposure evaluation**: This involves assessing the levels of radio frequency (RF) exposure around your station to ensure they are within the limits set by the FCC. The evaluation helps determine if the RF fields exceed the Maximum Permissible Exposure (MPE) limits.

2. **Prevent access to any identified high exposure areas**: If the evaluation identifies areas where RF exposure exceeds safe levels, operators must take steps to restrict access to these areas to protect people from excessive RF exposure.

### Why the Correct Answer is Correct:
- **C: Perform a routine RF exposure evaluation and prevent access to any identified high exposure areas**: This choice is correct because it directly addresses the requirements set by the FCC for ensuring RF safety. The FCC mandates that operators evaluate their stations to ensure compliance with RF exposure limits and take necessary actions to mitigate any risks.

### Why the Other Choices are Incorrect:
- **A: Post a copy of FCC Part 97.13 in the station**: While being familiar with FCC regulations is important, simply posting a copy of the rules does not ensure compliance with RF safety regulations. It does not address the need to evaluate or mitigate RF exposure.

- **B: Notify neighbors within a 100-foot radius of the antenna of the existence of the station and power levels**: Notifying neighbors is not a requirement for RF safety compliance. The focus is on evaluating and controlling RF exposure, not on informing neighbors.

- **D: All these choices are correct**: This is incorrect because choices A and B do not fulfill the specific requirements for RF safety compliance.

### Useful Formulas or Rules of Thumb:
- **Maximum Permissible Exposure (MPE)**: The MPE limits are defined by the FCC and vary based on frequency, power, and exposure time. Operators should refer to FCC guidelines to determine the specific MPE limits applicable to their station.

By focusing on evaluating RF exposure and controlling access to high exposure areas, operators can ensure they meet the necessary safety standards.
