Why is it important to avoid eating, drinking, or applying cosmetics in HD handling areas?

• A. To prevent contamination of surfaces
• B. To prevent inadvertent ingestion or contamination from hands or surfaces
• C. To comply with dietary restrictions
• D. To improve workflow speed

Answer: (B)

In hazardous drug handling, the priority is to minimize exposure and cross‑contamination. Eating, drinking, or applying cosmetics in HD areas creates direct pathways for drug residues to enter the body or be carried off surfaces. Residues on hands can be transferred to food or beverages, or to lips and mucous membranes, leading to inadvertent ingestion. Likewise, residues on surfaces can contaminate anything you touch or that comes into contact with your face or cosmetics, spreading contamination beyond the work area.

That’s why the best answer emphasizes preventing inadvertent ingestion or contamination from hands or surfaces. It captures both routes of exposure: through hands (hand-to-mouth transfer) and through contaminated surfaces. Other options miss one of these critical pathways or address unrelated issues, like dietary rules or workflow speed, which don’t speak to the safety risk involved.
