What is the function of the tank shut off?

Control burner temperature
Stop the flow of oil
Increase fuel supply
Measure fuel levels

The correct answer is: Stop the flow of oil

The function of the tank shut off is specifically to stop the flow of oil. This component acts as a safety mechanism within the fuel oil system of a boiler. When activated, the tank shut off will cut off the supply of fuel to the burner, preventing any potential overflow and ensuring that fuel does not leak or spill in the event of a tank failure or other issues. It's essential in maintaining operational safety and compliance with regulations, as it helps to avoid environmental hazards associated with fuel oil spills. This function is critical for maintaining both the integrity of the boiler operation and workplace safety, as unchecked fuel flow can lead to hazardous situations. Other options, such as controlling burner temperature, increasing fuel supply, or measuring fuel levels, represent different functions that may be performed by other components in the system, but they do not pertain to the specific role of the tank shut off.
