New York Low Pressure Boiler Certificate of Fitness (COF) Practice Test

The function of the low water cut-off in a boiler is crucial for safety and operational efficiency. This device is designed to monitor the water level within the boiler and act as a safety mechanism. When the water level drops below a predetermined point, the low water cut-off automatically shuts down the boiler. This prevents the boiler from running dry, which can lead to overheating, damage, and potentially dangerous situations such as explosions or fires.

Maintaining the correct water level is essential for the safe operation of a boiler, as it ensures that there is sufficient water to absorb heat and generate steam. By automatically shutting down the system when the water level is too low, this device protects both the equipment and the personnel operating or working near the boiler. This safety feature is standard in low pressure boilers to ensure compliance with safety regulations and best practices in boiler operation.
