This preparation is designed for mechanical professionals pursuing the Oklahoma Natural Gas Piping Journeyman license administered through the Oklahoma Construction Industries Board.

The Oklahoma Natural Gas Piping Journeyman classification is a specialized mechanical license covering natural gas piping from the point of delivery to the connections with appliances. Licensed journeymen may install, alter, modify, service, maintain, or repair natural gas piping within the scope established by Oklahoma law while working under the appropriate licensed Mechanical Contractor.

The current Oklahoma Natural Gas Journeyman examination is administered by PSI after the Oklahoma Construction Industries Board determines that an applicant meets the requirements for examination eligibility. The exam contains 30 scored questions, allows 90 minutes, and requires a minimum passing score of 70%. Candidates currently need 21 correct answers to meet the passing standard.

The examination concentrates heavily on practical gas-piping installation. Half of the test is devoted to pipe installation, making familiarity with indoor and outdoor piping, regulators, structural considerations, supports, joints, valves, outlets, sediment traps, and piping protection especially important. The remaining questions address general fuel-gas knowledge, pipe sizing, and construction safety.

This Oklahoma Natural Gas Journeyman online exam prep course uses the International Fuel Gas Code, 2018 with Oklahoma revisions and Code of Federal Regulations - 29 CFR Part 1926 (OSHA) to support organized preparation for the current licensing examination.

Exam Details

The Oklahoma Natural Gas Journeyman examination tests a candidate's knowledge of the installation, repair, alteration, and extension of gas piping and gas mains. It is a focused mechanical trade examination built around four major content areas.

The current examination contains 30 scored questions. Candidates receive 90 minutes to complete the test. A score of 70% is required, which currently equals 21 correct answers.

General Fuel Gas Piping — Knowledge, Definitions, and Regulations contains eight questions. Subjects include testing and inspection as well as pipe-material properties and requirements. Candidates should understand basic fuel-gas terminology, acceptable materials, inspection concepts, testing procedures, and the general requirements governing gas-piping systems.

Pipe Sizing contains four questions. Candidates should know how to use the applicable sizing methods and tables in the International Fuel Gas Code. Preparation should include understanding developed length, system demand, pressure considerations, pipe material, and the relationship between appliance input and required piping capacity.

Pipe Installation contains 15 questions, making it the largest category and representing half of the entire examination. Topics include indoor and outdoor installation requirements, gas pressure regulators, structural safety, hangers and supports, changes in direction, concealed locations, joints and connections, valves and controls, outlets, drip legs and sediment traps, and piping protection.

Safety contains three questions. The current outline identifies excavations, ventilation and confined spaces, personal protective equipment, signs, signals and barricades, fall protection, ladders and scaffolds, tools and equipment, and material safety information as areas candidates should understand.

The examination may also contain questions based on general industry practices and trade knowledge. Candidates should therefore combine code navigation with practical understanding of natural gas piping rather than relying entirely on looking up every answer during the test.

Open Book Test

The Oklahoma Natural Gas Journeyman examination is an open-book test. Candidates are responsible for bringing the approved reference materials they intend to use during the examination.

The primary approved code reference is the International Fuel Gas Code, 2018 Edition, with Oklahoma revisions. Code questions are based on the specific edition listed for the examination.

The current examination also allows Code of Federal Regulations - 29 CFR Part 1926 (OSHA) with the latest available amendments or the applicable selections prepared for the PSI examination program.

Approved references may be highlighted, underlined, and indexed before the examination. Candidates may use permanent tabs to organize important sections of the code.

Temporary tabs such as Post-it notes are not permitted and must be removed before the examination begins. Written notes are not allowed in approved reference materials before or during the examination.

Candidates may not bring additional loose papers into the test room with their approved references. Downloaded reference materials must be appropriately secured by spiral binding, hole-punching and placement in a binder, or another permitted binding method.

A silent, non-printing, non-programmable calculator may be used. Candidates may also request a magnifying glass at the testing center.

With 30 questions in 90 minutes, candidates have an average of three minutes per question. That is enough time for targeted code searches, but not for reading large portions of the book from the beginning. Efficient preparation should focus on knowing where major gas-piping subjects appear before test day.

Licensing Steps

1. Begin gaining qualifying mechanical trade experience. Work in the natural gas piping category within Oklahoma's mechanical licensing structure.
2. Register as a mechanical apprentice when required. Experience used toward journeyman qualification generally must be supported by proper apprentice registration unless it was lawfully obtained under an applicable exception.
3. Work under a licensed Mechanical Contractor. Supervised field experience allows applicants to develop the practical gas-piping skills required for journeyman licensing.
4. Accumulate the required experience. The standard Oklahoma journeyman pathway requires three years of verifiable mechanical trade experience in the category being pursued.
5. Use qualifying mechanical education when applicable. Approved education may substitute for a portion of the field-experience requirement under Oklahoma's approved education-and-experience combinations.
6. Maintain documentation. Keep apprentice registrations, employment verification, school records, transcripts, and other documentation needed to establish eligibility.
7. Submit the Mechanical License Application. Apply to the Oklahoma Construction Industries Board for Natural Gas Piping Journeyman examination eligibility.
8. Receive approval to test. The Board reviews the application and determines whether the applicant meets the requirements for examination.
9. Schedule the examination through PSI. Once approved, arrange an examination appointment with the state's testing provider.
10. Prepare the approved references. Organize the 2018 International Fuel Gas Code with Oklahoma revisions and OSHA 29 CFR Part 1926 according to current open-book rules.
11. Study the official examination categories. Concentrate on general fuel-gas knowledge, pipe sizing, pipe installation, and safety.
12. Take the Natural Gas Journeyman examination. Complete all 30 scored questions within the 90-minute testing period.
13. Earn the required passing score. Candidates currently need 70%, or 21 correct answers.
14. Complete license issuance. Follow the Oklahoma Construction Industries Board process for receiving the Natural Gas Piping Journeyman license after satisfying all applicable requirements.

State Requirements

Applicants for an Oklahoma mechanical journeyman license must be at least 18 years old.

The standard qualification route requires three years of verifiable mechanical trade experience in the category for which the applicant is applying. Oklahoma defines one year of verifiable experience as 2,000 hours.

For a Natural Gas Piping Journeyman applicant, qualifying experience should establish practical work in the natural gas piping category. Oklahoma generally requires experience to be obtained within the state's mechanical licensing structure and properly supported by apprentice registration unless an applicable exception exists.

Approved mechanical education can substitute for part of the experience requirement. An approved mechanical program containing at least 1,000 hours may be combined with one year of verifiable experience.

An approved program containing at least 500 hours may be combined with two years of experience. Oklahoma also recognizes qualifying programs containing 375, 334, or 250 hours when combined with the corresponding amount of verifiable mechanical experience required by state rules.

Equivalent verifiable mechanical experience obtained while serving in the United States military may also be considered toward journeyman qualification.

The Natural Gas Piping Journeyman license authorizes the license holder to install, alter, modify, service, maintain, or repair all natural gas piping from the point of delivery to the connections with appliances.

The journeyman performs authorized work while employed by the appropriate licensed Mechanical Contractor. The Natural Gas Piping Journeyman license does not independently provide the contractor authority required to operate a natural gas piping contracting business.

Oklahoma has adopted the 2018 International Fuel Gas Code, as amended and modified by the Oklahoma Uniform Building Code Commission, as the statewide minimum code for commercial fuel-gas construction. Candidates should prepare with the Oklahoma revisions that apply to the code edition used on the examination.

Mechanical journeymen are subject to Oklahoma continuing education requirements. Current rules require six hours of approved continuing education during the 36 months preceding license expiration, subject to applicable exemptions and licensing provisions.

If a candidate does not pass the examination on the first attempt, Oklahoma's current examination rules require a 30-day waiting period before retesting. For non-electrical examinations, subsequent failures generally require a 90-day waiting period.

Test Information and Study Materials

A strong Oklahoma Natural Gas Journeyman study plan should reflect the examination distribution. Because 15 of the 30 questions fall under Pipe Installation, candidates should devote approximately half of their technical study effort to installation-related subjects.

Prioritize Pipe Installation. Review indoor and outdoor piping requirements, regulators, structural safety, hangers and supports, changes in direction, concealed locations, connections, valves, outlets, sediment traps, and protection from physical damage.

Practice Pipe Sizing. Learn how to identify the correct sizing table and how to use system length, demand, pressure, and pipe material to select piping capacity. Do not wait until exam day to become familiar with the tables.

Review Testing and Inspection. Understand the code provisions governing pressure testing, inspection, test media, and the conditions required before a gas-piping system is placed into service.

Study Pipe Materials. Know where the International Fuel Gas Code addresses approved piping and tubing materials, joining methods, protection, and limitations.

Understand Pressure Regulators. Review regulator location, installation, venting-related considerations, and system pressure concepts that affect natural gas piping installations.

Study Joints and Connections. Become familiar with the requirements affecting threaded, mechanical, and other permitted gas-piping connections. Review where joints may be located and how piping is protected in concealed spaces.

Review Valves and Controls. Practice locating provisions for shutoff valves and understand how valve placement relates to appliance connections and system isolation.

Know Outlets, Drip Legs, and Sediment Traps. These subjects are specifically identified in the examination outline and should not be overlooked during preparation.

Study Piping Protection. Review protection from corrosion, physical damage, structural hazards, and conditions associated with indoor, outdoor, underground, and concealed installations.

Review OSHA Safety. Safety represents only three questions, but those questions can still determine whether a candidate reaches the passing score. Study excavation safety, confined spaces, PPE, fall protection, ladders, scaffolds, barricades, and tool safety.

Use permanent tabs strategically. Organize the International Fuel Gas Code around high-value subjects such as sizing, materials, testing, regulators, valves, supports, joints, and concealed piping. Keep the tab system simple enough to use quickly.

Practice with the actual code edition. Because code questions are based on the 2018 International Fuel Gas Code, preparation should use that edition with the applicable Oklahoma revisions.

Complete timed study sessions. Practice answering 30 questions in 90 minutes. Use the first pass to answer questions you know, then return to questions requiring more detailed code research.

Review mistakes by category. Separate missed questions into general knowledge, pipe sizing, installation, and safety. Within installation, track specific weaknesses such as regulators, supports, joints, valves, sediment traps, or concealed piping.
