Dampers are usually hidden away in ducts or ceiling cavities and seldom get much attention, but they’re a critical part of the fire protection strategy for many buildings. In a new Code Corner, NFPA Engineer Shawn Mahoney gives us a rundown of the different types of dampers, how they work, and what NFPA standards say (1:31). Then, we are joined by two experts from the National Energy Management Institute who tell us about the installation and maintenance of dampers, and some of the common problems that inspectors encounter out in the field (8:36).
