What should be done if a boiler is found to have low water levels?

If a boiler is found to have low water levels, the appropriate action is to immediately shut down the boiler and check for leaks or faults. This step is crucial for ensuring safety and preventing damage to the boiler. Low water levels can lead to overheating, which may result in dangerous situations such as boiler failure or explosions.

When the boiler is shut down, it allows the engineer to carefully inspect the system for any potential issues, such as leaks, malfunctions, or other faults that may have caused the water level to drop. Addressing these problems before restarting the boiler is essential to ensure it operates safely and efficiently.

Other choices may seem tempting but are not safe or effective responses to the situation. Simply increasing the fuel supply could worsen the problem by allowing the boiler to operate at an unsafe level. Turning off safety alarms would disable critical safety mechanisms designed to protect both the boiler and operators. Adding more water without inspecting the system first could lead to introducing water into a compromised boiler, which might cause further damage or hazards.
