Electrical Knowledge and Controls contains 15 questions. This section includes general electrical theory and knowledge, motors, AC and DC circuits, electrical meters, controls, and relays. Candidates should understand how electrical components interact with refrigeration equipment and how control problems can affect system operation.

Refrigeration Systems Operations also contains 15 questions. This category includes system troubleshooting, system operation, and system installation, maintenance, and repair. Candidates should practice connecting symptoms with possible refrigeration, electrical, piping, airflow, or component-related causes.

The Refrigerants category includes refrigerant types, refrigerant systems, and refrigeration theory. Candidates should understand the role of refrigerants in heat transfer and how refrigeration-system conditions affect performance.

Piping questions cover piping supports, piping materials and sizes, and piping pressure testing. Candidates should be comfortable recognizing applicable installation concepts and locating mechanical-code requirements when necessary.

The Safety section covers construction safety topics such as safety training requirements, ventilation, first-aid requirements, personal protective equipment, hazardous and toxic materials, lockout/tagout procedures, and ladders.

With 60 questions and 150 minutes, candidates have an average of approximately two and a half minutes per scored question. Efficient time management and reference navigation are important, especially when a question requires detailed research rather than direct trade knowledge.

Open Book Test

The Oklahoma Refrigeration Journeyman examination is an open-book test. Candidates are responsible for bringing permitted reference materials into the testing center and following the testing provider's requirements for those books.

The approved technical reference list includes the International Mechanical Code, 2018 edition with Oklahoma revisions; Modern Refrigeration and Air Conditioning; and Code of Federal Regulations - 29 CFR Part 1926 (OSHA). Later editions of non-code references are allowed in the test area, which makes Modern Refrigeration and Air Conditioning, 22nd Edition appropriate for preparation under the current examination rules.

Approved references may be highlighted, underlined, and indexed before the examination. Permanent tabs are permitted. Temporary tabs such as Post-it notes are not allowed. Candidates may not add written notes to the references before or during the examination session.

Open-book preparation should involve much more than simply owning the books. Candidates should learn the layout of each reference, recognize major chapters and subject areas, understand how indexes are structured, and practice finding information quickly.

The International Mechanical Code is especially useful for code-based installation questions involving mechanical systems, refrigeration equipment, piping, and related requirements. Modern Refrigeration and Air Conditioning supports broader technical study of refrigeration theory, electrical controls, equipment, system operation, troubleshooting, installation, maintenance, and repair.

Code of Federal Regulations - 29 CFR Part 1926 should be used for construction-safety preparation. Candidates should learn to recognize when a question is asking about OSHA rather than mechanical-code or refrigeration-theory requirements.

A practical open-book strategy is to identify the topic before opening a reference. Determine whether the question concerns electrical controls, refrigerants, piping, a refrigeration component, system operation, or safety. Then select the most appropriate reference and move directly to the relevant chapter or indexed subject.

Licensing Steps

The Oklahoma Construction Industries Board regulates mechanical journeyman licensing, including the Refrigeration Journeyman classification. Candidates must meet the applicable experience and application requirements before being authorized to take the examination.

1. Begin working in the mechanical trade. Gain refrigeration and mechanical experience under the licensing structure applicable to Oklahoma mechanical work.
2. Maintain apprentice registration when required. Oklahoma applicants who are not already licensed and want experience gained in Oklahoma to count toward licensing qualifications must maintain the required apprentice registration for applicable experience.
3. Build qualifying refrigeration experience. Accumulate verifiable mechanical experience in the category for which the Refrigeration Journeyman license is being pursued.
4. Meet an approved qualification pathway. Oklahoma recognizes qualifying experience as well as approved combinations of mechanical education and field experience.
5. Submit the Mechanical License Application. Provide the Oklahoma Construction Industries Board with the required application and supporting documentation.
6. Receive examination authorization. The Board reviews the application and determines eligibility for testing.
7. Schedule the examination through PSI. Approved candidates arrange the examination date, time, and location through the designated testing provider.
8. Prepare for the Refrigeration Journeyman examination. Review electrical controls, refrigerants, piping, components, system operation, troubleshooting, maintenance, repair, and safety.
9. Complete the examination. Achieve the required passing score as part of the journeyman licensing process.
10. Work as a licensed Refrigeration Journeyman. Journeymen work within Oklahoma's mechanical contractor structure under an active licensed Mechanical Contractor.

State Requirements

Applicants for an Oklahoma mechanical journeyman license must be at least 18 years old and meet one of the qualification pathways established for mechanical licensing.

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

Oklahoma also recognizes approved education-and-experience combinations. Depending on the number of approved instructional hours completed, qualifying candidates may use mechanical education toward a portion of the experience requirement while completing the remaining required field experience.

Equivalent verifiable mechanical experience obtained through qualifying United States military service may also be considered. Certain applicants holding a current and good-standing out-of-state mechanical license may qualify when the applicable Oklahoma requirements are satisfied.

For Oklahoma experience to count toward licensing qualifications, apprentice registration requirements must be followed when applicable. Maintaining accurate records of employment, hours, and mechanical work can help support the application process.

The Refrigeration Journeyman classification entitles the licensee to install, alter, modify, service, maintain, or repair refrigeration products, systems, or equipment, including process piping.

After obtaining the journeyman license, the licensee works within Oklahoma's mechanical licensing and supervision structure. Contractor licensing is a separate level with additional experience, examination, business, bond, insurance, and compliance requirements.
