What should be done with food before applying thermal fog?

• A. Place food outside the treated area.
• B. Close and seal all openings to buildings.
• C. Wrap food in plastic wrap.
• D. No food safety precautions are required.

Answer: (B)

When applying thermal fog, the fine droplets can drift beyond the treated area, so containment is essential to protect food and food-contact surfaces. Closing and sealing all openings to buildings creates a physical barrier that prevents fog from moving into food storage, kitchens, or other areas where food is present, reducing the risk of contamination. If possible, removing or covering food is also important, but sealing openings is the primary step to keep the treated space isolated. Wrapping food can help, and relocating food outside the treated area is good when feasible, but neither alone guarantees the same level of containment as securing the building envelope. Not taking any food precautions would risk contamination.
