What should an operator do if a malfunction in the boiler is suspected?

When a malfunction in the boiler is suspected, shutting down the boiler and conducting a thorough inspection is the most responsible and safe course of action. This approach is vital because boilers operate under high pressure and temperature, and any malfunction can lead to dangerous situations such as explosions or equipment damage. By shutting down the boiler, the operator can prevent potential hazards and ensure the safety of personnel and the facility.

A thorough inspection allows the operator to identify the specific nature of the malfunction, assess the condition of the boiler and its systems, and determine the necessary repairs or adjustments. This proactive response helps maintain the integrity of the boiler and ensures compliance with safety regulations.

Other options such as ignoring the problem, continuing operation until a complete failure, or adjusting controls without understanding the underlying issue could lead to catastrophic failures and incur significant safety risks and financial costs. Therefore, immediate inspection following a suspected malfunction is a foundational principle of boiler operation safety.
