Requires inspections of fire-life-safety damper devices

This bill requires regular inspections of fire safety dampers (devices that prevent fire/smoke spread through HVAC systems) in most non-residential Missouri buildings, excluding small homes. It mandates an initial inspection within 12 months of installation and subsequent checks every four years, following NFPA standards with physical visual inspections required (not remote methods). Inspectors must hold specific ICB certifications or equivalent, and building owners must maintain compliance records, issue deficiency reports for failures, and post public verification notices. These requirements apply to commercial buildings, schools, hospitals, and other multi-use structures governed by Missouri political subdivisions.
