Prep and pack area air pressure

CRCST practice question · Preparation & Packaging

Compared with the decontamination area, how should air pressure in the preparation and packaging area be maintained?

  • A. Positive pressure relative to adjacent areas
  • B. Negative pressure relative to adjacent areas
  • C. Neutral pressure with doors kept open
  • D. Negative pressure only during high-volume shifts

Answer

A. Positive pressure relative to adjacent areas

Clean work areas such as prep and pack are kept under positive pressure so air flows outward and keeps contaminants from coming in. Negative pressure is right for decontamination, where the goal is to hold contaminated air inside the room.
