In spill response, which step is performed last?

• A. Dispose of contaminated materials
• B. Protect yourself
• C. Clean and disinfect the area
• D. Wash hands

Answer: (D)

The important idea is that finishing cleanup with proper hand hygiene prevents any remaining contaminants from spreading. After you protect yourself, contain the spill, clean and disinfect the area, and dispose of contaminated materials, you complete the process with washing your hands. This final step removes any residue from skin or under the nails and prevents recontamination as you finish the task and resume work. It also ensures you don’t carry contaminants to other areas or to your face or PPE once cleanup is done.
