Which of the following best describes a layered approach to odor control during salvage?

• A. Ventilate only
• B. Use deodorants only
• C. Ventilate, use air scrubbers, and deodorants
• D. Seal area

Answer: (C)

A layered odor-control approach combines several methods to tackle odors from different angles, giving a stronger overall effect than any single tactic. Ventilation increases air changes and dilutes odor-causing compounds, reducing concentration quickly. Air scrubbers actively remove particulates and many VOCs from the air, addressing contaminants that cause smells and protect worker air quality. Deodorizers can neutralize or mask remaining odors, improving perceived cleanliness and comfort. Together, these steps attack odors at their source, in the space, and in perception, providing a more robust and reliable control during salvage than relying on ventilation or deodorants alone. Sealing the area might contain odors temporarily, but without active dilution and filtration, it can trap smells and delay cleanup.
