Exam Details

The Oklahoma Natural Gas Journeyman examination tests knowledge related to the installation, repair, alteration, and extension of gas piping and gas mains.

The examination contains 30 questions. Candidates are allowed 90 minutes to complete the test. The required passing score is 70%, which corresponds to 21 correct answers.

The examination is divided into four major content areas:

• General Fuel Gas Piping - Knowledge, Definitions, and Regulations: 8 questions
• Pipe Sizing: 4 questions
• Pipe Installation: 15 questions
• Safety: 3 questions

Pipe Installation is the largest portion of the exam, representing half of the scored questions. Candidates should give this area significant attention while still preparing across the entire examination outline.

General fuel gas piping questions include testing and inspection along with pipe material properties and requirements. Candidates should understand basic fuel gas terminology and know how to locate applicable code requirements when additional information is needed.

Pipe sizing is another important area. Candidates should practice using the sizing information contained in the International Fuel Gas Code rather than depending exclusively on memorization. Learning how to identify the correct table and apply the information is an important exam-preparation skill.

The safety portion addresses construction safety topics encountered during natural gas piping work. These subjects include excavations, ventilation and confined spaces, personal protective equipment, signs and barricades, fall protection, ladders and scaffolds, tools and equipment, and hazard communication.

Open Book Test

The Oklahoma Natural Gas Journeyman examination is an open-book test. Candidates may use approved reference materials during the examination.

The approved references include the International Fuel Gas Code, 2018, with applicable Oklahoma revisions, and the Code of Federal Regulations - 29 CFR Part 1926 (OSHA) with applicable current amendments.

Reference materials may be highlighted, underlined, and indexed before the examination session. Permanent tabs may be used to organize references. Temporary tabs such as Post-it notes are not permitted.

Candidates are responsible for bringing their approved references to the examination center. References may not contain written notes added before or during the examination session.

Although the exam is open book, candidates should not expect to research every answer from the beginning. With 30 questions and 90 minutes available, efficient time management is important. Candidates have an average of approximately three minutes per question, and some questions may require more time for sizing calculations or detailed code lookups.

Practice identifying the subject of a question before reaching for a reference. Determine whether the answer is most likely found in the International Fuel Gas Code or OSHA regulations, then use the index, table of contents, or chapter organization to move directly toward the applicable section.

State Requirements

Applicants for an Oklahoma mechanical journeyman license must be at least 18 years of age and meet the experience requirements established for the category in which they are applying.

One standard qualification pathway requires three years of verifiable experience in the mechanical trade in the applicable category. Oklahoma also recognizes qualifying combinations of approved mechanical education and mechanical trade experience.

For Oklahoma mechanical licensing purposes, one year of verifiable experience is 2,000 hours of qualifying mechanical work. Applicants relying on Oklahoma work experience toward their licensing qualifications should comply with applicable apprentice registration requirements.

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

A licensed journeyman works within Oklahoma's mechanical licensing structure and performs work within the scope of the applicable license classification. Candidates should understand both the technical requirements of natural gas piping and the limitations associated with the license they are pursuing.

Journeyman experience may also form part of the path toward a mechanical contractor license for candidates who later choose to advance to the contractor level. Oklahoma mechanical contractor applicants have additional experience and licensing requirements beyond the journeyman classification.

Reference Books

• International Fuel Gas Code, 2018
  The 2018 International Fuel Gas Code is the primary technical code reference for the Oklahoma Natural Gas Journeyman examination. It addresses fuel gas piping systems, materials, pipe sizing, installation, testing, inspection, regulators, valves, joints, connections, piping protection, and other requirements affecting natural gas systems. Candidates should become familiar with the structure of the code and practice locating tables and technical provisions efficiently.
• Code of Federal Regulations - 29 CFR Part 1926 (OSHA)
  This federal construction safety reference contains OSHA standards applicable to construction work. It supports preparation for exam topics involving excavations, ventilation, confined spaces, personal protective equipment, signs and barricades, fall protection, ladders, scaffolds, tools, equipment, and hazard communication.

These books should be incorporated into regular exam preparation. Candidates who repeatedly work with the same references can build stronger familiarity with chapter locations, terminology, tables, and safety regulations.

Test Information and Study Materials

A productive study plan for the Oklahoma Natural Gas Journeyman examination should combine technical knowledge with direct practice using the approved books. Begin with the International Fuel Gas Code and learn how the reference is organized before attempting large numbers of practice questions.

General fuel gas piping knowledge should form the foundation of preparation. Study common terminology, definitions, testing procedures, inspection requirements, and pipe material provisions. Understanding the language used in the code can make questions easier to interpret and can help candidates identify where an answer is likely to be found.

Testing and inspection deserve focused review. Natural gas piping systems must meet applicable testing requirements before being placed into service. Candidates should understand the purpose of testing and become comfortable locating the relevant code provisions.

Pipe materials are also part of the exam outline. Review requirements involving acceptable piping materials, joints, connections, protection, and installation conditions. Candidates should understand that different piping situations may have different requirements and limitations.

Pipe sizing should be practiced regularly. Learn how to determine the information needed for a sizing question and how to locate the appropriate sizing table. Rather than trying to memorize an entire table, develop the ability to identify and apply the correct information efficiently.

Pipe installation accounts for 15 of the 30 examination questions, making it the largest subject area. Candidates should devote a substantial portion of study time to this category.

Installation 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.

Breaking these subjects into smaller study sessions can make preparation more manageable. One session may focus on hangers and supports, while another covers valves and controls or concealed piping. Once individual subjects become familiar, candidates can combine them into mixed practice sessions.

The safety portion of the examination should not be overlooked. Review OSHA requirements involving excavations, confined spaces, ventilation, PPE, fall protection, ladders and scaffolds, tools, equipment, warning systems, barricades, and hazard communication.

Practice using 29 CFR Part 1926 by subject so you become familiar with the structure of the safety regulations. When a safety question requires a lookup, knowing where a topic is generally located can help reduce search time.

Timed practice is particularly useful for this examination. With 90 minutes available for 30 questions, candidates should develop a pace that allows enough time for both straightforward questions and reference-based research.

When working through practice questions, first determine whether you can answer confidently from knowledge. When research is necessary, identify the appropriate reference before opening the book. This prevents unnecessary searching through sections that are unlikely to contain the answer.

Reference navigation becomes more efficient through repetition. The more often you locate sizing tables, installation provisions, definitions, safety requirements, and testing rules during study, the more familiar the books become.
