Explanation
Halon is a type of fire extinguishing agent that is effective in suppressing fires. However, it is not limited to Class "A" fires only. Halon can also be used on Class "B" and Class "C" fires, making it versatile in combating different types of fires. Therefore, the given statement that Halon can only be used on Class "A" fires is false.

Explanation
The statement is false because after flames have been put out, the crew cannot immediately go back to normal duties. They need to ensure that the area is safe and free from any potential hazards before resuming normal activities. This may involve conducting inspections, assessing damage, and implementing necessary repairs or precautions. Only when it is confirmed that the situation is under control and there is no further risk, can the crew resume their regular duties.

Explanation
Activating the CO2 system while someone is still in the engine room can be fatal because CO2 displaces oxygen and can lead to asphyxiation. When the CO2 system is activated, it releases a large amount of carbon dioxide into the space, reducing the oxygen levels. If someone is present in the engine room at that time, they may not have enough oxygen to breathe, leading to suffocation and potentially causing death. Therefore, it is crucial to ensure that the engine room is evacuated before activating the CO2 system to prevent any potential harm to individuals.

Explanation
Different types of fires require different types of fire extinguishers. For example, water extinguishers are suitable for fires involving paper and wood, while CO2 extinguishers are effective for electrical fires. Using the wrong type of fire extinguisher can be ineffective or even dangerous. Therefore, it is not true that any fire extinguisher can be used on any type of fire.
