Actions taken to confine a product release to a limited area, performed remotely, are considered to be:

• A. Defensive strategies
• B. Containment
• C. Evacuation
• D. Mitigation

Answer: (A)

Defensive strategies are actions taken to protect people and the environment by preventing the release from spreading and by isolating the hazard. When you perform steps from a distance to keep a product release to a limited area, you’re applying a protective, strategic approach designed to defend safety—often involving remote actions like shutting valves, isolating equipment, or establishing a controlled perimeter. These kinds of remote, protective measures fit under defensive strategies because they aim to minimize exposure and prevent further dispersion of the hazard.

Contamination or containment refers to actually keeping the material within a specific area, which is part of the goal but is a more specific tactic than the broader defensive approach. Evacuation focuses on moving people away, not on keeping the release confined. Mitigation is about reducing the consequences after the release has started, rather than the proactive containment from a distance. So the best description for the described actions is defensive strategies.
