1.Walk me through setting up a work area before removal starts.
Why they ask
Setup is where most of the protection comes from. They want to know you understand the order and the reason for each step, not just that you've hung plastic before.
How to answer
- Post warning signs and shut down or seal the HVAC so it can't pull dust through the building
- Pre-clean the area with a HEPA vacuum and wet wipes before covering anything
- Seal vents, doors and openings with critical barriers, then line floors and walls with poly
- Build the decon unit at the entrance and start the negative air machines
- Check the manometer to confirm negative pressure before anyone starts removal
