I am a former instrumentation and electrical technician (2004–2021, oil & gas and pharmaceutical). The attached comment responds to Questions 3, 5, 7, 8, 9, 13, 16, 17 and 18. It documents an unregulated residential exposure within the RFI’s scope: high-frequency noise voltage conducted on household wiring in the 2–150 kHz band, from switch-mode power supplies and electronic utility meters. Federal conducted-emission limits (47 CFR 15.107) begin at 150 kHz, and ANSI C12.1-2022 exempts the most common residential meter form from harmonic testing. I include laboratory and personal field measurements, a balanced summary of the health evidence, my own documented case, and six specific recommendations. I ask HHS to define this exposure, fund a validated measurement method with NIST and NIOSH, and coordinate with the FCC to close the 2–150 kHz gap.
