What statement must be clearly visible on a control panel in an x-ray system?

The statement that must be clearly visible on a control panel in an x-ray system is "Caution: X-rays produced when energized." This warning is essential because it alerts operators and personnel to the potential hazards associated with the use of x-ray equipment. When the system is energized, it produces x-rays, which can be harmful if proper safety precautions are not followed.

The visibility of this message is crucial for safety, as it serves as a reminder to ensure that the x-ray equipment is operated within safe parameters and that personnel are protected from unnecessary exposure. This cautionary statement is specifically mandated by regulatory standards to ensure that anyone using or near the equipment is aware of the associated risks and understands the importance of adhering to safety protocols.

This particular message effectively emphasizes proactive safety measures, as it indicates that the risk is present when the equipment is powered on, which is a fundamental aspect of radiation safety practices.
