Why is it important to have no openings in ductwork installed in a garage area?

Having no openings in ductwork installed in a garage area is crucial primarily due to the prevention of fire hazards. Garages often contain flammable materials such as gasoline, oils, and other chemicals that can pose serious fire risks. If ductwork has openings, it can allow for the transfer of harmful fumes or smoke from a fire in the garage to other areas of the home, potentially spreading the fire and making it more difficult for occupants to escape. Furthermore, contaminants present in a garage can infiltrate the HVAC system through those openings, compromising the air quality in the home and introducing additional fire risks if those materials ignite.

While enhancing energy efficiency, increasing ventilation, and providing easy access for maintenance are important considerations in HVAC system design, the primary concern in this scenario revolves around safety and minimizes the risk of a fire spreading throughout the home. Therefore, proper sealing of ductwork in a garage area is an essential safety measure to protect against fire hazards.
