What safety feature is required for steam boilers in New Jersey?

The low-water cutoff device is a crucial safety feature required for steam boilers because it prevents the boiler from operating when the water level is too low. If the water level drops below a safe threshold, the device automatically shuts off the boiler, which helps to prevent overheating and the potentially catastrophic consequences of a dry-fired boiler. This feature is vital in ensuring the safety of both the equipment and the personnel operating it, as low water conditions can lead to severe damage, explosion, or other hazardous situations.

While other features like an emergency shut-off valve, pressure relief valve, and steam gauge play important roles in the overall safety and functionality of a steam boiler, the low-water cutoff specifically addresses the immediate risk of running the boiler without sufficient water, making it essential for safe operation in line with New Jersey regulations.
