How many fire pumps are located on board, according to the standards?

The correct answer indicates that there are five fire pumps located on board, which aligns with the standards set for maritime safety and emergency preparedness. Fire pumps are critical for firefighting operations on vessels, providing the necessary water supply in the event of a fire. The standards are often influenced by factors such as ship size, occupancy, and various safety regulations, which dictate the need for adequate pumping capacity to ensure effective response to fire emergencies.

In many maritime regulations, having a specific number of fire pumps ensures redundancy and reliability in firefighting systems. Five fire pumps might be determined as the standard to ensure that there is a sufficient supply of firefighting water in different areas of the vessel, allowing for multiple simultaneous firefighting operations if needed. This setup enhances the overall safety and emergency readiness of the ship, ensuring crew and passenger protection.

The other options regarding the number of fire pumps may not adhere to the typical standards expected on a vessel of a certain size or type, which is why they fall short of being the correct answer.
