After cleaning a flood-damaged area in a cancer center, what step should be completed next?

• A. Disinfecting with diluted bleach solution and drying the area
• B. Replacing all fixtures without cleaning
• C. Ventilating with windows closed for 24 hours
• D. Reoccupying the area immediately

Answer: (A)

After flood cleanup, the priority is to remove contaminants and inactivate remaining microbes. Cleaning handles visible soil, but pathogens can linger on surfaces. Disinfecting with a diluted bleach solution and then drying the area completes this safety step: the disinfectant lowers the microbial load, and drying prevents moisture that can support mold and ongoing contamination. In a cancer center, protecting immunocompromised patients makes thorough disinfection followed by drying essential. Use the correct surface-contact time and ensure the area is fully dried before considering reoccupation. Replacing fixtures without cleaning bypasses disinfection, sealing off the area without addressing microbes, and simply ventilating with windows closed doesn’t remove contamination or moisture; reoccupying immediately risks exposure.
