What must be done to spectrally reflective surfaces in Area S before lazing operations commence?

The correct approach before conducting lazing operations in Area S is to remove, cover, paint, or destroy spectrally reflective surfaces. These surfaces can create dangerous and unpredictable reflection of laser energy, which poses a significant risk both to personnel and equipment.

The removal or covering of such surfaces ensures that the laser beams operate in a controlled environment, mitigating the chances of unintended reflections that could cause harm or degrade operational effectiveness. Using paint or other materials to cover these reflective surfaces can also help by absorbing laser energy rather than reflecting it. This is crucial for maintaining safety and operational efficiency during lazing operations.

Options that suggest leaving reflective surfaces uncovered, enhancing their reflective qualities, or securing the area with fences would fail to address the real safety risks involved with reflections in laser operations, thereby neglecting essential safety precautions.
