During a boiler inspection, what component is critical to check for proper function?

Water chemical balance
Pressure relief valves
Insulation thickness
Structural integrity of pipes

The correct answer is: Pressure relief valves

The proper functioning of pressure relief valves is crucial during a boiler inspection because these valves are essential for maintaining safety and preventing hazardous conditions. Pressure relief valves are designed to automatically release excess pressure from the boiler when the internal pressure exceeds a predetermined level. This function is vital in preventing potential boiler explosions or other dangerous situations resulting from overpressure. Regular checks ensure that these valves are not blocked, stuck, or malfunctioning, which would prevent them from operating correctly during an emergency. Ensuring their reliability is a key part of maintaining overall boiler safety. While other components like water chemical balance, insulation thickness, and structural integrity of pipes are important for the efficiency and longevity of the boiler, they do not directly safeguard against the immediate risks associated with excessive pressure build-up, making the pressure relief valves a critical focus during inspections.
