HHS-OASH-2026-0397-3768 https://www.regulations.gov/comment/HHS-OASH-2026-0397-3768 Our family is very concerned about any increases in RF/EMF in our area. We have 2 vaccine injured/ autistic grand kids. We limit their exposure to screens and wi-fi whenever they are with us and we see a marked difference in behavior. We also turn off our devices & wi-fi at night. We have ceased using Bluetooth ear buds and are also looking at ways to shield our home electric 'smart' meter. Please carefully consider any and all expansions of RF/EMF. Thank you
