Can NIH provide additional detail specifying which people affiliated with NIH are (or are not) covered under NIH’s federal liability coverage?

NIH is not able to provide additional detail, due to the complexity of federal law and policy, and the unknown facts of a hypothetical event, that would determine coverage for any specific case. An example of a federal statute governing liability coverage is the Federal Tort Claims Act (FTCA), 28 U.S.C. §§1346(b), 2401(b), 2671-80 et seq. You should speak to your institution’s legal counsel if you have additional questions or interest regarding the FTCA.
