I am interested in learning about recommended safety practices and best practices. I have heard of companies placing signs on floors indicating not to stand next to RFID machines for more than 30 minutes a day.
The really are no safety best practices yet. In most cases, passive ultrahigh-frequency (UHF) readers are not placed in locations where people will be exposed to radio emissions for more than a few seconds. In general, readers should be kept at least 3 feet from people, particularly their head, and people should not be exposed to reader emissions on a continuous basis. So a sign that warns not to stand in from of reader antennas is probably a good idea.
