Excel file for testing dampers that lists access requirements
The installation of fire and life safety (FLS) systems is an essential part of both new and existing building. Fire Smoke Dampers (often abbreviated as FSD) are among the most important of them. These devices are installed wherever a heating, ventilation, and air conditioning (HVAC) duct penetrates a fire-rated wall, ceiling, or floor. In the event of a fire, these devices should be able to stop flames and smoke from spreading through the HVAC ductwork, allowing occupants more time to evacuate the building and contributing to the reduction of the amount of damage caused by the fire. However, as buildings and systems age and as physical, mechanical, or electrical problems emerge, dampers can become inoperable. This leaves the duct as an open channel for fire and smoke in the event of a fire, and the facility runs the danger of being shut down owing to a lack of compliance. Verifying and documenting that essential FLS building systems perform as expected is accomplished through the process of testing and maintaining fire smoke dampers.
