Definition

A Fire Damper is a device intended for use in horizontal assemblies required to have a fire-resistance rating. It incorporates protective ceiling membranes and operates to close off a duct opening through the membrane in the event of a fire.

Purpose

The purpose of a Fire Damper is to prevent the spread of fire and smoke through ductwork by automatically closing upon detection of high temperatures or fire. This helps contain the fire and limits damage to the building.

Examples of Use

  • HVAC Systems: Installing fire dampers in heating, ventilation, and air conditioning ducts to enhance fire safety.
  • Commercial Buildings: Using fire dampers to comply with fire safety regulations and protect occupants.
  • Industrial Facilities: Implementing fire dampers in duct systems to prevent fire spread in critical areas.

Related Terms

  • Ductwork: A system of ducts used for air distribution in buildings.
  • Fire-Resistance Rating: A measure of the ability of a material or assembly to withstand fire for a certain period.
  • Smoke Damper: A device similar to a fire damper, but specifically designed to restrict the passage of smoke.

Notes

  • Regular maintenance and testing are essential to ensure fire dampers function correctly in an emergency.
  • Fire dampers must be installed according to building codes and standards to be effective.
