OK Fire Sprinkler study guide
OK Fire Sprinkler · Work through your exam, one topic at a time.
An Oklahoma fire sprinkler license is the state credential that allows a contractor to bid, install, and alter automatic sprinkler systems, and allows individual fitters to perform that work under a licensed contractor. Oklahoma regulates this trade at the state level rather than through municipal licensing alone, and the protective-health side of state government has historically administered it. The OK Fire Sprinkler study guide has 10 sections and about 3,480 words.
01Codes, Standards, and Licensing Administration
This domain tests whether you can name the document that governs a given sprinkler decision, who may legally perform the work in Oklahoma, and how a project moves from permit application to final sign-off. NFPA 13 - commercial, industrial, institutional, and residential buildings beyond the 13R limits.
345 words, about 2 min02Water Supply Analysis and Hydraulic Calculations
This domain checks your ability to build a demand, test a supply, and run the math that proves one meets the other. Read the density from the occupancy curve at the remote area size, then multiply density by area to get sprinkler flow.
379 words, about 2 min03System Types and Design Criteria (Occupancy Hazard, Density/Area, Special Occupancies)
This domain tests whether you can pick the right system type for the occupancy and apply the density/area method and its adjustment rules correctly. Wet pipe: the default wherever freezing is not a risk; fastest and most reliable.
379 words, about 2 min04Sprinklers and System Components (Heads, Valves, Alarms, Flow Switches)
This domain tests sprinkler selection, spacing, and the valve and alarm devices that make a system work and report. K-factor sets the flow for a given pressure; 5.6 is the common commercial size, with larger K-factors for storage and high-challenge occupancies.
373 words, about 2 min05Piping, Fittings, Materials, and Joints
This domain tests whether you can select listed pipe and joining methods for the service conditions and avoid the corrosion and pressure failures that show up in inspection reports. Black steel Schedule 40 or Schedule 10, galvanized steel, copper, CPVC, and PEX where the standard permits them; every material must be listed for fire protection service.
355 words, about 2 min06Hangers, Restraint, and Seismic Protection
This domain tests support spacing, restraint of forces, and the seismic provisions that keep pipe in place during an earthquake. Maximum spacing is 12 ft for pipe 1 inch and smaller, and 15 ft for 1 1/4 inch and larger.
357 words, about 2 min07Fire Pumps, Tanks, and Water Storage
This domain tests the fire pump performance envelope, the accessories that protect it, and the storage behind it. A fire pump must deliver 100 percent of rated flow at rated pressure, at least 150 percent of rated flow at not less than 65 percent of rated pressure, and a shutoff pressure not exceeding 140 percent of rated pressure.
342 words, about 2 min08Plan Review, Permits, and Field Inspection
This domain tests submittal completeness, review judgment, and the inspection sequence that keeps a job legal and buildable. A complete submittal identifies the owner and contractor, the occupancy and commodity classification, ceiling and roof construction, pipe sizes and materials, sprinkler make, model, K-factor and temperature, hydraulic calculations, water supply data, hanger and seismic details, head count, and signage.
310 words, about 2 min09Acceptance Testing, Inspection, Testing, and Maintenance
This domain tests the acceptance tests that prove a new system works and the recurring routines that keep it working. Hydrostatic test, main drain flow test, alarm and waterflow device test, dry pipe or preaction trip test, fire pump flow test, and a walkthrough confirming valve positions, signage, and spare sprinkler stock.
318 words, about 2 min10Jobsite Safety and Coordination with Other Trades
This domain tests whether you can work safely at height, in trenches, and around other trades without creating hazards or damaging the system you are installing. Fall protection is required at six feet in construction; guardrails at 42 inches, and ladder use at the proper angle with three points of contact.
