Which process focuses on safely removing hazardous materials from an environment?

• A. Decontamination
• B. Remediation
• C. Containment
• D. Ventilation

Answer: (B)

Remediation is the process of safely removing hazardous materials from an environment. In infection control risk assessment, the goal is to eliminate or neutralize hazards so the space becomes safe for occupancy and use. Remediation covers actions like cleaning up chemical spills, abating asbestos, removing lead-based materials, or addressing mold growth, all with the aim of physically removing the hazard from the environment or reducing its presence to acceptable levels.

Decontamination, on the other hand, is about removing contaminants from people or objects that have already been exposed or contaminated, not primarily about removing the hazard from the environment itself. Containment focuses on stopping the spread of a hazard during cleanup, rather than removing the hazard from the environment. Ventilation improves air quality by moving or filtering air, but it doesn’t remove the hazard itself—it reduces exposure by dilution or filtration.

So the activity that centers on safely removing hazardous materials from the environment is remediation.
