Limits of Human Exposure to Radiofrequency Electromagnetic Fields in the Frequency Range from 3 KHZ to 300 GHZ - Safety Code 6

4. Safety Procedures for Operators and Maintenance Personnel of RF Devices (RF Workers)

1. Maintenance personnel and operators of RF devices shall be aware of the potential hazards of RF fields.
2. Particular care shall be taken to ensure that all people are clear of any direct beam of an RF device before it is switched on for test or maintenance purposes.
3. Instructions and procedures for repair, maintenance and operation of a device, as specified by the manufacturer or a competent person, shall be readily available to, and be followed by, operators and maintenance personnel.
4. Replacement components shall be equivalent to original components. Transmission lines, waveguides, gaskets, flanges and similar components shall have the same operating characteristics as the original components or be approved by the manufacturer of the original equipment, or a person trained in the safe use of this equipment.
5. Testing of a device either before or after completion of any repair work shall be carried out after protective shields, waveguides and other components have been replaced in their designated locations.
6. The correct operation of electronic test equipment and power meters shall be checked in advance, i.e., prior to using them at the repair station or test site.
7. Adjustment of voltages, replacement of RF energy generating components, dismantling components or refitting transmission lines shall be undertaken by persons specially trained for such assignments. The services of a qualified repair person should be sought when any malfunction is suspected.
8. The correct operation of all safety interlocks shall be tested and operators shall not defeat any safety interlock.
9. An RF generating component shall be tested with an appropriate load connected to its output or with the radiated energy absorbed by anechoic material. The energy generated shall not be allowed to radiate freely into occupied areas.
