Perfecting Safety: Where are Fire Dampers Required?
Fire safety is a critical consideration in any building, from residential homes to sprawling commercial complexes. One often overlooked component of a comprehensive fire safety strategy is the fire damper. What is a fire damper, and more importantly, where are fire dampers required? In this article, we'll answer these questions and more, to provide you with all the information you need to make informed decisions about your fire safety needs.
What Are Fire Dampers?
Fire dampers are devices installed in ductwork that automatically close when exposed to heat, in order to effectively prevent the spread of fire through a building's HVAC system. Fire dampers are constructed using fire-resistant materials and are operated typically by a fusible link made from heat-sensitive material. When the link is exposed to excessive temperatures, the link is released, which allows the fire damper to slam shut. The primary function is to act as a barrier that seals off sections of ductwork to contain the spread of fire and maintain the integrity of escape routes.
Where Are Fire Dampers Required?
Requirements for fire dampers are ultimately the responsibility of the authority having jurisdiction (AHJ). These authorities administer building codes, typically based on widely adopted standards from organizations like the International Code Council (ICC) and the Association of Refrigeration and Air Conditioning Engineers (ASHRAE) for example. These requirements are typically further broken down by the type of building.
In commercial settings, fire dampers are essential for safeguarding large numbers of people and valuable assets. They are often required in the following areas:
- Fire-rated assemblies
- Elevator shafts
- Corridors and hallways
In commercial buildings, fire safety is designed to slow the spread of fire while protecting exit pathways for occupants. Fire dampers installed in these locations prevent fire from spreading between floors, keep escape routes clear of fire, and maintain the integrity of the fire-rated division walls. Careful attention to fire safety and fire damper installation helps to contain fire and smoke within individual areas, to allow more time for emergency services to respond and occupants to evacuate.
In multi-story residential buildings such as apartments or condominiums, fire dampers can be particularly useful. In these large buildings, fire dampers provide many of the same functions, and are often installed in the following locations:
- Fire-rated walls
- Occupancy separation walls
- Laundry rooms
- Horizontal exit walls
- Corridor walls and ceilings
Fire dampers in multi-story residential buildings provide many of the same functions as in commercial buildings with additional requirements. In residential buildings, occupants may be sleeping when a fire breaks out, which increases the time required for occupants to evacuate. Fire dampers play a critical role in limiting the spread of fire in these types of buildings and they help maximize the time for emergency services to respond.
Fire dampers are crucial in healthcare settings, where even a small fire can have devastating consequences. They are often required in:
- Fire-rated assemblies
- Corridor walls and ceilings
- Operating rooms
- Patient rooms
Healthcare facilities are a blend between the risks of commercial buildings and multi-story residential buildings. Many of the occupants in a healthcare facility by definition will be receiving care and would be less able to respond quickly should a fire occur. Fire dampers help keep these structures safe in order to allow time for emergency services to respond and fires to be contained.
When Is a Fire Damper Required?
Building codes and local regulations often dictate when a fire damper is required. However, a good rule of thumb is to install them anywhere ducts penetrate fire-rated assemblies.
Any duct passing through a fire-rated wall or floor should have a fire damper. Without a fire damper, the fire-rated assembly has an obvious weak point should a fire occur. Fire dampers often have a breakaway connection to the ductwork as well so that, in case of a fire, the ductwork may fall away from the fire-rated assembly, but the fire damper will stay in place.
Any location with a higher potential for fire should have a fire damper as well. High-risk locations can utilize fire dampers to mitigate the increased likelihood of fire. Fire damper location should be just one part of an overall fire control and life safety plan.
