Class 5 Boiler Practice Exam 2025 - Free Boiler Certification Practice Questions and Study Guide

The correct response relates to the American Society of Mechanical Engineers (ASME) code specifically governing controls in automatically fired boilers, which is CSD-1. This code outlines essential safety requirements for the design, construction, and performance of automatic controls in these types of boilers. It ensures that proper preventive measures are established to safeguard operations, including the necessary interlocks and alarms to prevent unsafe conditions.

CSD-1 is focused on maintaining operational safety in automatically fired boilers by detailing the functions and responsibilities of various control systems. These include the requirements for reliable operation, responsiveness in a range of situations, and the prevention of hazardous boiler conditions that can arise from control failures. Compliance with this code is vital for promoting effective and safe boiler operation, aligning with industry best practices.

In contrast, CSD-2, CSD-3, and CSD-4 address other types of boiler installations and their respective controls. While they provide valuable guidelines, they do not specifically regulate automatically fired boilers in the same depth as CSD-1. Understanding each code's specific focus helps clarify the safety and operational standards applicable to various boiler configurations.
