Question

A pharmaceutical plant layout designed to minimize cross-contamination should follow _______

• A. Random workflow
• B. Unidirectional material flow
• C. Multidirectional material flow
• D. Centralized storage

Hint:

Unidirectional material flow prevents backtracking and helps reduce cross-contamination in pharmaceutical plants.

Answer 1

The Correct Option is B

Concept:
Plant layout is very important in pharmaceutical manufacturing because it affects quality, safety, and contamination control.

Step 1: Meaning of cross-contamination.
Cross-contamination occurs when one material contaminates another material or product.

Step 2: Role of material flow.
If material moves in multiple directions, chances of mixing, confusion, and contamination increase.

Step 3: Unidirectional flow.
Unidirectional material flow means materials move in one planned direction from raw material area to processing area to finished product area.

Step 4: Final answer.
Therefore, unidirectional material flow minimizes cross-contamination. \[ \boxed{\text{Unidirectional material flow}} \]
