What are two major hazards associated with a poorly vented dryer?

• A. Excessive noise and energy waste with no safety risk.
• B. Improved drying speed and reduced humidity in the living space.
• C. Increased indoor air quality due to venting indoors.
• D. Lint buildup leading to fire, and moisture/heat buildup causing mold or equipment damage.

Answer: (D)

Poor venting creates two big hazards: a fire risk from lint buildup and moisture/heat buildup that can cause mold and equipment damage. Lint trapped in ducts is highly flammable, and when the exhaust path is restricted or undersized, lint can accumulate and ignite from the dryer’s heat, leading to a dangerous fire. At the same time, moisture and heat that can’t escape properly raise indoor humidity, which promotes mold growth in walls and ceiling spaces and can damage the dryer, ducts, insulation, and surrounding structures. The other options ignore these safety risks or describe outcomes that aren’t true for poorly vented dryers.
