GA Fire Sprinkler study guide
GA Fire Sprinkler · Work through your exam, one topic at a time.
The Georgia Fire Sprinkler Contractor License is a state credential administered through the Office of the State Fire Marshal. It authorizes an individual to contract for the design, installation, alteration, repair, and maintenance of water-based fire protection systems in Georgia. The GA Fire Sprinkler study guide has 8 sections and about 3,311 words.
01NFPA 13 Design Criteria, Occupancy Classification, and System Types
This domain tests whether you can turn a building's use and contents into a defensible NFPA 13 design: the hazard class, the density/area point, the hose allowance, and the system type that fits the space. NFPA 13 groups occupancies into light hazard (LH), ordinary hazard Group 1 and Group 2 (OH1, OH2), and extra hazard Group 1 and Group 2 (EH1, EH2).
406 words, about 2 min02NFPA 13 Spacing, Coverage, Obstruction Rules, and Hydraulic Calculations
This domain tests layout geometry and the math that proves the layout works: maximum sprinkler spacing, maximum protection area per head, distance to walls, obstruction rules, and the hydraulic path from the remote head to the supply. For standard spray sprinklers, the common limits are: Light hazard: 15 ft between sprinklers, 225 ft² per sprinkler, 7.5 ft to walls Ordinary hazard: 15 ft, 130 ft², 7.5 ft to walls Extra hazard: 12 ft, 100 ft², 6 ft to walls Keep at least 6 ft between sprinklers unless baffles or listed arrangements permit closer spacing, to avoid cold-soldering and poor spray overlap.
436 words, about 2 min03NFPA 13R and NFPA 13D Residential and Low-Rise Systems
This domain tests the residential standards that sit outside the full NFPA 13 rules. The exam expects you to know scope limits, design sprinkler counts, pressures, duration, and the specific spaces where heads may be omitted.
423 words, about 2 min04NFPA 25 Inspection, Testing, and Maintenance
This domain tests whether you know what NFPA 25 requires, how often, and the difference between an inspection (looking), a test (operating), and maintenance (repairing). The exam often presents a component and asks for its interval.
355 words, about 2 min05Water Supply Analysis, Fire Pumps, and Standpipe Systems
This domain tests whether you can prove the supply side of the demand: available flow at the required pressure, how a fire pump changes the curve, and how standpipe requirements add to the system demand. A flow test records static pressure, residual pressure, and flow.
443 words, about 2 min06Georgia Rules and Regulations for Fire Sprinkler Contractors and Licensing
This domain tests Georgia-specific licensing and contractor responsibility. The exam expects you to know who may contract for sprinkler work, what the license covers, and how state rules interact with local permits.
439 words, about 2 min07Georgia Code Adoption, Permitting, and Plan Review Procedures
This domain tests the administrative path from design to acceptance: which code edition applies, what a permit submittal contains, how plan review works, and what inspections close out the job. Georgia adopts the International Fire Code as the Georgia Fire Code, with state amendments, and that code references NFPA 13, 13R, 13D, and NFPA 14 for sprinkler and standpipe design.
413 words, about 2 min08General Trade Knowledge, Safety, and Jobsite Practices
This domain tests the practical side of sprinkler work: safe installation practices, coordination with other trades, protection of materials, and the jobsite behaviors that prevent injuries and failed inspections. Follow OSHA construction requirements and the site-specific safety plan.
