I have heard many comments about the FCC RF safety regulations. Some people find them to be cumbersome and consider them to be bureaucratic nonsense. They don't think that such rules are necessary and do not believe that they need to be told how to be RF-safe. I disagree with this attitude. When the FCC RF safety regulations were written, and then later applied to hams, I welcomed them.
RF safety is less tangible than many other safety issues.
If you have exposed electrical wires in your home, it is pretty obvious that they are dangerous. No one should need to tell you that a dead tree should be removed before it falls on someone. If, however, your station exposes people to unsafe levels of RF, it is not immediately obvious. You often cannot sense that your body is absorbing too much RF energy, and it requires sophisticated measuring devices or complicated modeling estimates to tell that a dangerous situation is occurring. The FCC RF safety regulations for hams are very wisely written.
