MI Boiler Operator study guide
MI Boiler Operator · Work through your exam, one topic at a time.
The Michigan Boiler Operator credential is issued through the Michigan Department of Licensing and Regulatory Affairs (LARA), Bureau of Construction Codes. It is aimed at people who operate and maintain steam and hot-water heating boilers and who need to demonstrate competence to a state licensing authority, typically stationary engineers, building maintenance technicians, institutional plant staff, and industrial facility operators. Our practice material is independent study content; it is not affiliated with, endorsed by, or produced by LARA or the State of Michigan, and it is not an official question bank. The practice set is organized around six domains weighted to reflect the operational emphasis of the trade: boiler construction, design, and installation (20%); boiler operation and maintenance (25%); safety devices and controls (20%); codes, standards, and regulations (15%); combustion and fuel systems (10%); and water treatment and boiler feedwater (10%). The MI Boiler Operator study guide has 6 sections and about 2,013 words.
