Which of the following best describes the primary purpose of the control & limit step?

• A. To notify authorities only.
• B. To contain any release of harmful agents and protect the safety of the crew.
• C. To secure the cargo.
• D. To prepare a final report.

Answer: (B)

Containment and safety are the focus of the control & limit step. When a hazardous release occurs, the main goal is to stop the release from getting worse and keep people and the environment safe. This means taking actions to limit the substance to the smallest area possible, establishing perimeters, isolating the source if it can be done safely, and ensuring responders use proper PPE and procedures. By quickly containing the release and protecting the crew, you reduce exposure, curb environmental impact, and prevent escalation. Notifying authorities, securing the cargo, or preparing a final report are important parts of incident management, but they are not the primary aim of this step. The primary purpose is to contain the release and protect the safety of the crew.
