Did you know?




Accreditation surveys such as those conducted by The Joint Commission and State Agencies are now checking the validity of “unable to test” dampers. You can now be cited if they determine the damper has been able to be tested all along.


Unfortunately, there are numerous inspection companies and facilities that overuse the “unable to test” classification for dampers which are difficult to inspect. These dampers are then placed on a PFI to be tested at a later date. This practice is only intended to cover dampers that are in highly sensitive patient areas or are legitimately obstructed by construction or utility features. Inspectors at Life Safety Enterprises Inc. go above and beyond to find and inspect every single damper in every single facility we enter. LSE takes a tremendous amount of pride in accessing the inaccessible!


Smoke and Fire Dampers are located in HVAC duct systems and are designed to close and prevent the passage of smoke and fire throughout the building. Dampers work in a variety of ways to accomplish their intended goals. Fire dampers use fusible links which melt at a specified temperature allowing a curtain to close via gravity or tension springs. Smoke dampers are typically interconnected to the fire alarm system and use either pneumatic or electric motors to close louvers.


Because of their inherent importance, LSE will look at every wall (including the floor) to determine where dampers may be located. We will not rely on past inspection reports or as-built drawings, which may not reflect the current building configuration. 


LSE will inspect the damper for functionality, correct installation, accessibility and damage. In addition, we will also indicate where dampers may be needed and are not currently present based on code requirements. Each damper curtain or louver will be given their own unique bar code identifier which will then be plotted on your Life Safety Code drawings.



Additional Damper Information:


  • Code requirements listed in NFPA 80, 101 and 105

  • Required Testing Frequencies

    • Acceptance Testing / Commissioning

    • 1 Year after installation

    • 4 years in all non-hospital facilities

    • 6 years in hospitals

  • Yes, LSE does perform Acceptance Testing and Commissioning!

  • Historically, 15% of all dampers that we test will fail inspection.

  • Exercising smoke dampers during fire alarm testing does not count as a required inspection. Each damper must be visually inspected and confirmed to have closed.

  • ALL dampers are required to be inspected and maintained even if the wall is no longer rated.

  • LSE will place a decal on every duct containing a damper to indicate that the damper has been tested including the date of the inspection.

  • LSE can also provide damper repair services



Once complete, LSE will provide a comprehensive inspection report listing the pass / fail status of all dampers. Detailed Work Orders will be generated for any damper that does not meet code requirements, identifying the exact reason for failure making it easy to repair the issues.
