The main idea is that these two terms address different parts of protecting people and environments from hazards. Containment is about keeping the agent from spreading into the environment or into other areas of the facility. It involves measures that create barriers to release, such as isolation rooms, appropriate facilities and engineering controls, proper handling of contaminated materials, and decontamination to prevent environmental contamination. Exposure control, by contrast, is about preventing people from being exposed to the agent in the first place. It relies on personal protection and preventive actions—use of personal protective equipment, vaccination where available, and safe procedures and practices to minimize contact with the agent.

So, containment focuses on preventing environmental spread, while exposure control focuses on preventing staff and patient exposures through PPE, vaccination, and proper procedures. This distinction helps explain why the described approach is the best answer: it accurately pairs environmental protection with individual protection.
