What key safety measure is important for preventing boiler explosion risks?

Maintaining proper pressure levels is crucial in preventing boiler explosion risks because boilers are designed to operate within specific pressure limits. When the pressure inside a boiler exceeds these limits due to malfunction, blocked safety valves, or other issues, it can result in catastrophic failure or explosion. Pressure gauges need to be regularly monitored to ensure they remain within safe operating ranges. If pressures begin to approach dangerous levels, operational protocols should involve immediate action to reduce the pressure, such as venting steam or reducing fuel supply. This safety measure directly affects the structural integrity of the boiler and acts as a fundamental line of defense against potential hazards.
