What is a common action taken to ensure boiler safety before operation?

Safety valve testing is crucial for ensuring boiler safety before operation. Safety valves are designed to automatically release pressure from the boiler when it exceeds a predetermined limit, preventing potential explosions or catastrophic failures. Regular testing ensures that these valves function properly, allowing them to protect the system in case of an overpressure scenario. This action helps maintain safe operating conditions and is a fundamental practice in boiler safety management.

While fuel inspection, water quality testing, and electrical inspection are all important components of overall boiler maintenance and safety, they do not specifically address the immediate pressure control mechanisms that safety valves provide. Therefore, safety valve testing stands out as a primary action that directly impacts the operational safety of a high-pressure boiler.
