Question 273Steam Plants - 1st Asst/Chief

The correct answer is C) Secure the fuel oil to that boiler. When the water level in a boiler rapidly falls out of sight, the first and most critical action is to immediately secure the fuel oil supply to that boiler. This prevents further firing and overheating of the boiler, which could lead to a potentially dangerous situation. Securing the fuel oil is the most immediate action required to address the rapidly dropping water level and prevent further damage. The other options, such as raising the feed pump pressure or blowing down the gage glass, should be carried out after the fuel oil has been secured, as they are secondary actions aimed at restoring the proper water level and boiler operation.
