What essential checks should be performed before starting a boiler?

Before starting a boiler, it is crucial to perform several essential checks to ensure safe and efficient operation. Inspecting water levels is fundamental because insufficient water can lead to overheating and potential damage to the boiler. Verifying the fuel supply is equally important; the boiler must have a proper and safe fuel source to operate effectively. Additionally, ensuring that safety devices function correctly is vital for preventing accidents and ensuring the safety of the operation. These devices can include pressure relief valves, low-water cutoffs, and other safety controls that protect both the equipment and personnel.

While the other options may include important aspects related to boiler maintenance and operation, they do not encompass the immediate and essential checks required prior to launching the boiler. For instance, checking the surrounding temperature, while useful for understanding environmental conditions, is not directly tied to the operational readiness of the boiler. Calculating the boiler’s age and efficiency may help in assessing overall performance but is not a practical check before starting it. Cleaning the exterior can help maintain the boiler over time, but it does not address critical safety and operational checks necessary before initiating operation.
