HHS-OASH-2026-0397-4434 https://www.regulations.gov/comment/HHS-OASH-2026-0397-4434 I am an electric engineer that visits high EMF areas regularly for work. Most of the sites have signage that states “radio frequency hazard” or similar warnings. I believe the excess exposure may have lead to cognitive issues, and possibly had an effect on my immune and nervous systems.
