Which label is used to identify fire and smoke dampers on building plans?

The correct label used to identify fire and smoke dampers on building plans is "FIRE/SMOKE DAMPER." This designation is important because it indicates that the damper serves the dual purpose of both controlling the spread of fire and managing smoke movement within the HVAC system. In many jurisdictions, including North Carolina, building codes require clear and accurate labeling on plans to ensure that contractors, inspectors, and others involved in the construction and safety of the building can properly identify the function and requirements for these components. Using "FIRE/SMOKE DAMPER" communicates that the damper is engineered to meet the specific fire and life safety criteria outlined in the building code, thus reinforcing the importance of fire safety measures in the design of the building's heating, ventilation, and air conditioning systems.
