On-station monitoring is performed during an attack to determine if there is a vapor hazard inside the ship. When is this monitoring performed?

• A. After the attack
• B. Only during decontamination
• C. During the attack
• D. Before the attack

Answer: (C)

During an attack, on-station monitoring is done in real time to detect vapor hazards inside spaces so you can act immediately. Hazards can appear or change quickly once damage occurs, so having sensors active while the attack unfolds lets you decide if entry is safe, whether protective gear is needed, and what ventilation or isolation steps to take right away. Monitoring after the attack would be too late to protect people, and monitoring only before or solely during decontamination wouldn’t catch hazards that arise during the attack itself.
