Confinement refers to which concept?

• A. The procedures to evacuate an area
• B. The distance to a release
• C. The procedures to keep a material in a defined or local area
• D. The process of neutralizing a chemical

Answer: (C)

Confinement means keeping a hazardous material contained within a defined area so it cannot spread beyond that zone. In practice, this is about creating barriers and a controlled boundary—sealing off rooms, closing openings, and establishing a perimeter—to prevent contamination of surrounding areas and make it easier to manage the release. The goal is to limit exposure and simplify subsequent mitigation steps. This concept is different from evacuating people (that option focuses on moving everyone away from danger), different from maintaining distance from the release (which is about how far people should be kept from the hazard, not keeping the material itself in one area), and different from neutralizing the chemical (which aims to change or destroy the hazard rather than containing it).
