(5) The effectiveness of mitigating both acute and cumulative exposures to wildfire smoke, including wildfire smoke in the built environment, in decreasing adverse health effects from such wildfire smoke. (c) Best practices Not later than 6 months after completing the human health risk assessment under subsection (a), the Director of the National Institute for Occupational Safety and Health shall develop and publish best practices to mitigate worker exposure to wildfire smoke, including wildfire smoke in the built environment. Such best practices shall be informed by the human health assessment completed under subsection (a). (d) Authorization of appropriations There is authorized to be appropriated to the Director of the National Institute for Occupational Safety and Health to carry out this section $1,000,000 for each of fiscal years 2027 through 2036.
