In responding to a FOIA request, are there any MSHA records that I should not release?

All records are “FOIAable”; however, not all records can be released under the FOIA. Congress established certain categories of information that are not required to be released in response to a FOIA request because release would be harmful to an agency or private interest. Therefore, some or parts of records can be withheld if protected by an exemption. Even if an exemption applies, agencies may use their discretion to release information when there is no foreseeable harm in doing so and disclosure is not otherwise prohibited by law.
