Health facilities: other; surgical smoke plume evacuation plan; require. Amends 1978 PA 368 (MCL 333.1101 - 333.25211) by adding sec. 20187.
HB 4779 requires Michigan health facilities performing certain surgical procedures to implement smoke evacuation systems. It directly affects hospitals and surgical centers using heat-producing tools like lasers or electrosurgery, which generate harmful surgical smoke. The bill mandates facilities to develop policies ensuring a dedicated evacuation system captures and neutralizes smoke at the source before it reaches staff or patients' eyes or lungs. This policy change aims to protect healthcare workers and patients from exposure to potentially harmful smoke byproducts during procedures.

The bill text was reformatted to remove draft markings and standardize the layout, but the core legal content remains identical. The substantive policy requiring surgical smoke evacuation systems for heat-producing procedures, along with its specific definitions and one-year implementation timeline, is unchanged.
TECHNICAL
Removed draft headers, page numbers, and editing marks while preserving the original legislative text.
Corrected a typo in the enacting clause where 'peoplE' was changed to 'People'.
