How often must exhaust ducts for domestic clothes dryers be supported and secured in place?

• A. Every 2 feet
• B. Every 4 feet
• C. Every 6 feet
• D. Every 8 feet

Answer: (B)

Exhaust ducts for domestic clothes dryers must be supported and secured every 4 feet. This requirement is crucial for several reasons. First, proper support ensures that the duct maintains its integrity and does not sag or become damaged, which could lead to restrictions in airflow or create areas where lint can accumulate. Over time, such accumulations can pose a fire hazard. Additionally, adequately securing the duct prevents any movement or disconnection that might occur due to vibrations from the dryer during operation. To enhance safety and compliance with building codes, following the 4-foot interval for support helps align with best practices designed to promote effective and safe venting of exhaust from the dryer.
