Which condition must be monitored to prevent boiler explosions?

Water temperature
Pressure levels
Fuel quality
Air circulation

The correct answer is: Pressure levels

Monitoring pressure levels is crucial in preventing boiler explosions because excessive pressure can indicate a malfunction or failure in the boiler system. Boilers are designed to operate within specific pressure limits, and if the pressure exceeds these limits, it can lead to a catastrophic failure, such as an explosion. Pressure gauges should be regularly checked to ensure that the boiler operates safely. Relief valves and other pressure control mechanisms must also be functional to release excess pressure before it reaches dangerous levels. Failure to monitor and manage pressure levels can result in serious accidents, making this an essential aspect of boiler safety protocols. While other factors like water temperature, fuel quality, and air circulation are important for efficient boiler operation and overall system health, they do not directly relate to the immediate risks of explosion caused by pressure malfunctions.
