What hazard does the collective protection system (CPS) protect the ship from?

The collective protection system (CPS) is designed to safeguard personnel and assets onboard a ship from airborne chemical, biological, and radiological (CBR) contaminants. This system functions as a protective measure that helps maintain a safe environment in situations where such hazardous materials are present, ensuring that the air supply remains uncontaminated.

In a maritime context, exposure to CBR threats can potentially incapacitate crew members or compromise the operational capability of the vessel. The CPS acts as a barrier against these contaminants by utilizing filtration systems and controlled environments, effectively reducing the risk of exposure during CBR incidents. Understanding this function is crucial for appropriate ship safety and operational readiness, especially in scenarios where contamination could lead to severe consequences.

While other options represent significant hazards, such as explosive debris, flooding, and electrical hazards, the primary role of the CPS specifically addresses airborne CBR contaminants. This distinction is important for effective hazard management on naval or maritime vessels.
