What is the best hazard mitigation approach in dealing with sanitation issues?

• A. isolation
• B. separation
• C. containment
• D. elimination

Answer: (B)

Separating activities and areas to keep clean operations separate from contaminated ones directly reduces the chance that pathogens or waste will cross into safe zones. This approach creates distinct zones, clear workflows, and controlled access, which means people, surfaces, and equipment that could spread contamination stay apart from where clean work happens. You can implement it with physical barriers, dedicated tools and PPE for each zone, separate supply lines, and signage or color-coding to maintain the separation.

Isolation would remove people from the hazard entirely, which can be impractical for ongoing sanitation work. Containment concentrates the hazard in a bounded space but still relies on preventing movement into other areas; separation goes further by structuring how work flows and who can access which areas to minimize cross-connection. Elimination is the most thorough solution, but not always feasible in real-world sanitation systems, whereas separation offers a practical, effective way to lower exposure while keeping operations running.
