When blowing off a boiler, what should the operator have an assistant do?

When blowing off a boiler, having an assistant watch the gauge glass level is essential for ensuring safety and proper operation. The gauge glass provides a clear visual indication of the water level within the boiler. Monitoring this level during the blow-off process helps prevent several potential issues, such as a drop in water level that could allow the boiler to operate in an unsafe condition, which might lead to overheating or damage.

An assistant keeping an eye on the gauge glass can alert the operator if the water level rises too high or drops too low, facilitating a safe and controlled blow-off process. Proper supervision during this procedure is critical to maintaining safe operating parameters and ensuring equipment integrity.
