Topics Covered on the Oklahoma Natural Gas Contractor Exam

The exam covers four main areas, each weighted differently based on their importance to your daily work:

General Fuel Gas Piping – Knowledge, Definitions, and Regulations (10 questions)
This section tests your understanding of the International Fuel Gas Code (IFGC) and Oklahoma-specific regulations. You'll need to know definitions, working space requirements, appliance installation standards, and general code compliance. These questions often involve interpreting code language and applying regulations to specific scenarios.

Pipe Installation (15 questions)
As the largest section, pipe installation questions focus on proper installation techniques, material identification, connection methods, and system interconnections. You'll see questions about labeling requirements, meter installations, and proper installation procedures for various pipe materials. This is where your hands-on experience really pays off.

Pipe Sizing (12 questions)
These questions test your ability to calculate proper pipe sizes for different gas loads and pressures. You'll work with sizing equations, C-values for natural gas, and pressure drop calculations. Mathematical problem-solving skills are essential here, and understanding the relationship between flow rates, pipe diameter, and pressure is crucial.

Safety (3 questions)
While only three questions, safety is non-negotiable in natural gas work. These questions cover OSHA requirements, contractor responsibilities, and general safety protocols. Don't underestimate this section – safety violations can end careers and endanger lives.

Sample Questions: Test Your Knowledge

Let's look at some actual exam-style questions to give you a feel for what you'll encounter. Remember, we won't give away the answers here – that's what our practice exam is for!

Question 1: When two or more meters are installed on the same premises supplying separate consumers, the piping systems may be interconnected on the outlet side of the meters for convenience.

This true/false question tests your understanding of meter installation regulations and system interconnections – a common scenario in multi-unit buildings.

Question 2: According to the Oklahoma Fuel Gas Code, for other than steel pipe, exposed gas piping shall be identified by a yellow label marked "Gas" in black letters at intervals not exceeding what distance?
A) 3 feet
B) 4 feet
C) 5 feet
D) 10 feet

This question tests specific code requirements for pipe identification – the kind of detail you need to memorize.

Question 3: According to OSHA, the prime contractor can be relieved of overall responsibility for safety compliance by subcontracting all of the work to a subcontractor.

Another true/false question focusing on contractor responsibilities – crucial knowledge for anyone running a business.

Question 4: You are installing a gas furnace in a commercial building's mechanical room. The building owner wants to know what the minimum working space requirement is in front of the control side of the appliance. According to the IFGC, what do you tell the owner?
A) A level working space not less than 24 inches deep and 24 inches wide
B) A level working space not less than 30 inches deep and 30 inches wide
C) A level working space not less than 36 inches deep and 36 inches wide
D) A level working space not less than 48 inches deep and 30 inches wide

This practical scenario question tests code knowledge in a real-world context.

Question 5: According to the IFGC, the C value for natural gas at standard conditions used in the pipe sizing equations is 0.6094.

This true/false question tests your knowledge of specific calculation constants used in pipe sizing.
