An indoor air quality issue often addressed by selecting low-VOC finishes is what?

• A. Moisture resistance
• B. Fire resistance
• C. Off-gassing and emissions that can affect occupant health
• D. Structural performance

Answer: (C)

Low-VOC finishes address off-gassing and emissions that can affect occupant health. VOCs are chemicals released from paints, sealants, varnishes, and other finishes into indoor air. Even at low levels, these emissions can irritate eyes, nose, and throat, trigger headaches, or contribute to longer-term health concerns with prolonged exposure. By choosing finishes with low volatile organic compounds, the amount of contaminants released into the air is reduced, improving indoor air quality for occupants. The other options deal with different performance goals: moisture resistance focuses on preventing dampness and mold, fire resistance concerns safety in fire scenarios, and structural performance relates to the strength and durability of the material.
