Designed specifically for aspiring journeymen in Minnesota, this audio guide cuts through the noise and delivers the critical, must-know information you need to not only pass the test but to excel in your career.
Join two experienced professionals as they break down the complex world of fire protection, translating dense code language into practical, on-the-job insights. This isn't a dry, academic lecture; it's a straight-talking, no-BS guide that feels more like a conversation with seasoned mentors over a cup of coffee.
In this essential exam prep, you will master:
The NFPA Playbook: Unpack the key differences and applications of NFPA 13, 13D, and 13R. Understand the specific roles of NFPA 14, 20, 22, 24, 25, 72, 96, and 17A and how they all interconnect.
Sprinkler Head Savvy: Learn the non-negotiable rules for sprinkler coverage areas across light, ordinary, and extra hazard occupancies. Master the temperature ratings, bulb colors, and specific requirements for residential, ESFR, and storage heads.
System Deep Dives: Gain a rock-solid understanding of wet, dry, pre-action, and antifreeze systems. We cover everything from freezing protection and air pressure requirements to valve configurations and the specific quirks of each system type.
The Lifeblood of the System: Explore the critical requirements for fire pumps, water supplies, and tanks. Learn the rules for pump room construction, suction and discharge piping, and the essential details of pressure tanks and water storage.
Hanging Tough: Master the art and science of pipe support and installation. This section covers everything from hanger spacing for steel, copper, and CPVC to the specific rules for sway bracing, riser support, and dealing with unique obstructions.
Standpipe Systems: Know your classes. We break down the crucial distinctions between Class I, II, and III standpipe systems, including their required flows, pressures, pipe sizes, and FDC placement rules.
Minnesota's Own Rules: Go beyond the national standards and learn the specific Minnesota state statutes and fire code amendments that will be on your exam. This includes unique rules on control valve supervision, fire extinguisher allowances, FDC height, and state-specific licensing laws and penalties.
Every rule, every measurement, and every clearance requirement in the codebook exists for a reason, often written in the aftermath of tragedy. This guide will help you understand the "why" behind the rules, transforming you from a test-taker into a true professional who understands the immense responsibility that comes with installing life-saving systems. Stop just memorizing facts and start genuinely understanding your craft. Good luck, you've got this.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
