Where should fire and smoke dampers be located?

Fire and smoke dampers are crucial safety components designed to prevent the spread of smoke and fire through ductwork and other openings in fire-resistant walls. Their placement is governed by specific requirements outlined in the building and mechanical codes to ensure effective containment and protection of occupants, as well as to maintain the integrity of the building's fire-rated assemblies.

Locating fire and smoke dampers at prescribed locations as specified in the code helps to ensure that they are positioned where they will be most effective in restricting the movement of smoke and fire. The code details the criteria for their placement, which includes factors such as proximity to fire-resistive barriers, the type of occupancy, and the configuration of air distribution systems. This systematic approach is essential for maintaining safety throughout the building and effectively controlling the spread of fire.

By adhering to the prescribed locations, you ensure compliance with safety regulations and enhance the overall efficacy of the fire protection system within a structure. This strategic positioning, rather than ad-hoc or arbitrary placements, is critical for effective life safety and property protection measures.
