What is the purpose of the "Rules for Care of Power Boilers" as per ASME Code Book?

The purpose of the "Rules for Care of Power Boilers" as outlined in the ASME Code Book focuses on ensuring safety during boiler operation. These rules provide a framework that outlines best practices and procedures to maintain boiler integrity, prevent accidents, and promote safe operation among engineers and operators. By detailing maintenance protocols, inspection schedules, and operational guidelines, these rules support the overarching goal of minimizing risks associated with boiler operation.

The emphasis on safety reflects the critical nature of boiler systems in various industrial applications, where failures can result in catastrophic events. In contrast, cost management, material guidelines, and efficiency standards play important but more specialized roles in the context of boiler function and performance, but they do not encompass the comprehensive safety focus that the ASME Code aims to provide. Thus, this aspect of the ASME Code is dedicated specifically to enhancing the safe use and management of power boilers, making it the right answer.
