What must be included by the designer on the building plans regarding fire dampers?

The requirement for the designer to include the identification of fire dampers on the building plans is essential for ensuring the safety and compliance of the building's mechanical systems with fire prevention protocols. Fire dampers are critical components in HVAC systems that help to prevent the spread of fire and smoke through ducts and openings in fire-rated walls and floors.

By identifying the locations and specifications of fire dampers, the designer not only complies with various codes and standards but also facilitates proper installation and future maintenance. This identification aids contractors and inspectors in verifying that the fire dampers are appropriately placed and function correctly within the system. Including this crucial information in the building plans ensures that all parties involved in the project are aware of how fire protection measures are integrated into the mechanical systems, thereby enhancing the overall safety of the structure.
