When cleaning a work area, you should start at the furthest point from the door and end at which location?

• A. Floor
• B. Ceiling
• C. Center
• D. Door

Answer: (A)

The key idea is to clean in a systematic, contamination-controlling order: start far from the door and work toward the exit, usually top to bottom so that dust falls downward onto surfaces you’ll clean last. Finishing on the floor fits this approach because gravity pulls debris downward, so you capture and remove it in the final step before leaving. This minimizes spreading dust to areas you’ve already cleaned and ensures you can mop or wipe up the last of the debris as you finish. The ceiling or walls are handled earlier in the sequence, and the door isn’t the finish point because you don’t want to recontaminate yourself or cleaned surfaces as you exit.
