If an authority having jurisdiction requests installation of firestop materials around a fire damper in a fire-rated wall, what is the best action to take?

The best course of action is to consult the damper manufacturer for the approved method of sealing. This step is essential because the manufacturer provides specific guidelines that are tailored to their products, ensuring that the installation meets both safety and regulatory standards. Fire dampers are critical components in fire safety systems, designed to prevent the spread of fire and smoke through ductwork in fire-rated walls.

Using the manufacturer’s approved method is crucial because it guarantees the integrity of the fire-rated wall and the effectiveness of the fire damper in an emergency situation. This approach also helps in complying with the requirements set forth by the authority having jurisdiction, as they expect installations to follow best practices as per manufacturer specifications.

Relying solely on standard installation methods or general firestop guidelines may not address the unique aspects of the particular damper being installed, potentially compromising fire safety. Installing the damper without sealing is not an option, as it would not meet fire safety standards or the authority's requirements, thereby posing a risk of fire and smoke spread.
