Nevada Pipeline And Conduits Contractor (A-19) Books Allowed into Exam Package

Prepare for the Nevada Pipeline And Conduits Contractor (A-19) examination with a focused exam-room package that includes the approved reference candidates are permitted to use during the trade test: NFPA 30, Flammable and Combustible Liquids Code, 2018.

The Nevada A-19 Pipeline and Conduits examination is an open-book test, but candidates may use only approved reference material in the testing room. This package is designed specifically for candidates who want the exam-room-approved NFPA 30 reference rather than the broader group of study-only books used for gas piping, water piping, excavation, welding, paving, safety, and Nevada One Call preparation.

The A-19 trade examination contains 60 questions, allows 2 hours for completion, and requires 42 correct answers to pass. The exam covers Gas Piping, Water Piping, Welding, Safety, Paving, Excavation, Compaction and Grading, and Nevada One Call.

Gas Piping and Water Piping are the two largest examination categories, with 15 questions each. The A-19 scope also includes excavation, trenching, boring, shoring, backfilling, compacting, paving, surfacing, and protective coatings associated with pipeline and conduit installations. Candidates should therefore prepare for the complete underground construction process rather than pipeline materials alone.

The NFPA 30, Flammable and Combustible Liquids Code, 2018 supports study involving flammable and combustible liquid systems, piping-related provisions, storage and handling concepts, and associated safety requirements. Since it is the approved reference in this package for exam-room use, candidates should become familiar with its organization before test day.

Open-book testing should be approached strategically. Candidates have an average of about two minutes per question, so searching the reference from the beginning for every answer can consume valuable time. A stronger preparation method combines technical knowledge with efficient code navigation so the approved book can be used when a specific requirement needs to be confirmed.

Exam Details

The Nevada A-19 Pipeline and Conduits Contractor examination contains 60 questions. Candidates are allowed 2 hours to complete the examination and must answer 42 questions correctly to pass.

The examination content is divided into the following areas:

• Gas Piping: 15 questions
• Water Piping: 15 questions
• Welding: 6 questions
• Safety: 8 questions
• Paving: 5 questions
• Excavation, Compaction and Grading: 8 questions
• Nevada One Call: 3 questions

Gas Piping is one of the two largest sections. Candidates should understand gas-pipeline materials, fittings, joining methods, installation procedures, protective methods, trench considerations, and other construction concepts associated with gas transmission and distribution work.

Water Piping also accounts for 15 questions. Preparation should include pipe materials, installation methods, trench preparation, fittings, joining, bedding, backfilling, compaction, and related underground water-pipeline work.

Safety accounts for 8 questions and should receive substantial preparation. Pipeline and conduit construction can involve excavation hazards, heavy equipment, traffic, buried utilities, lifting, tools, hot work, and changing jobsite conditions.

Excavation, Compaction and Grading also accounts for 8 questions. Candidates should understand how proper earthwork supports the pipeline installation from trench preparation through backfill and surface restoration.

Welding, Paving, and Nevada One Call complete the examination outline and reflect the broad field responsibilities associated with underground pipeline and conduit work.

Open Book Test

The Nevada A-19 Pipeline and Conduits examination is an open-book test.

The NFPA 30, Flammable and Combustible Liquids Code, 2018 is the exam-room-approved reference included with this package.

Candidates should become familiar with the structure of NFPA 30 before test day. Practice locating subjects involving flammable and combustible liquids, piping, storage, handling, and related safety requirements so code searches can be completed efficiently during the timed examination.

Open-book testing still requires strong trade knowledge. Most A-19 topics extend beyond a single code book, so candidates should prepare for gas piping, water piping, welding, excavation, paving, safety, and Nevada One Call before entering the exam.

The goal is not to search the book for every answer. Candidates should understand the underlying trade concept first, then use NFPA 30 strategically when a specific requirement needs to be located or confirmed.

Timed reference-navigation drills can be useful. Choose a topic, locate the applicable section, and track how long the search takes. Repeat difficult topics until the organization of the book becomes more familiar.

Licensing Steps

The A-19 trade examination is one part of the Nevada contractor licensing process. Applicants must complete the applicable qualification, application, examination, and licensing requirements before a contractor license is issued.

1. Confirm the A-19 classification. Make sure Pipeline and Conduits matches the work the business intends to perform.
2. Identify the qualifying individual. The contractor application must designate the person responsible for satisfying the applicable trade qualification requirements.
3. Document qualifying experience. Prepare the work-history information required for the requested contractor classification.
4. Submit the Nevada contractor license application. Complete the applicable application and supporting documentation.
5. Receive examination eligibility. After the application and qualification information are reviewed, the qualifying individual can proceed with the required examinations.
6. Prepare for the A-19 trade examination. Study gas piping, water piping, welding, safety, excavation, grading, compaction, paving, and Nevada One Call.
7. Practice NFPA 30 navigation. Use the 2018 code during preparation so relevant sections can be located efficiently during the open-book exam.
8. Prepare for Nevada Business and Law. Contractor applicants must also satisfy the applicable Nevada Business and Law requirement unless an authorized waiver applies.
9. Complete the required examinations. Take the applicable trade and business examinations associated with the licensing process.
10. Complete the remaining licensing requirements. Finish the additional state requirements associated with contractor license issuance.

State Requirements

Nevada classifies A-19 Pipeline and Conduits within General Engineering contracting.

The scope includes the fabrication and installation of electrical conduits and pipelines, together with trenching, boring, shoring, backfilling, compacting, paving, surfacing, and application of protective coatings necessary to complete the installation.

The classification also encompasses work associated with water pipelines, gas pipelines, and underground electrical conduits. This broad scope explains why the A-19 examination includes several different construction disciplines rather than focusing only on one type of pipe.

Pipeline and conduit work requires coordination between earthwork, pipe installation, joining, safety, underground utility awareness, and surface restoration. Candidates should understand how each part of the process affects the final installation.

Excavation is especially important because pipelines and conduits are installed underground. Contractors must understand trench preparation, safe access, shoring concepts, bedding, backfill, and compaction along with the technical requirements of the pipe system itself.

Surface restoration is also part of the classification. When trenching disturbs pavement or other finished surfaces, the work may require proper compaction and paving before the project is complete.

Test Information and Study Materials

A strong Nevada A-19 preparation plan should combine broad pipeline and conduit knowledge with efficient use of the NFPA 30 reference.

Gas Piping should receive substantial attention because it accounts for 15 questions. Candidates should understand the basic construction sequence for underground gas piping, including trench preparation, materials, fittings, joining, protection, and installation considerations.

Candidates should also understand how gas-piping work differs from water-piping work. The system purpose, materials, joining methods, testing considerations, and protective requirements can vary depending on the type of pipeline involved.

Water Piping also accounts for 15 questions. Preparation should include pipe materials, fittings, trench conditions, bedding, joining, backfilling, compaction, and installation practices.

Water-pipeline work can involve different types of pipe and fittings. Candidates should understand how installation requirements change depending on the material and site conditions.

Excavation, Compaction and Grading should be studied as part of the pipeline installation process rather than a separate subject. A successful underground installation begins with proper site preparation and continues through trenching, bedding, backfill, compaction, and final grade.

Improper earthwork can affect the performance of the installed pipeline. Poor bedding, inadequate backfill, or insufficient compaction can contribute to settlement, movement, or damage.

Safety should also receive significant study time. Pipeline construction can involve trenches, excavation equipment, traffic, buried utilities, suspended loads, tools, welding, and other hazards.

Candidates should understand the importance of hazard recognition, personal protective equipment, safe access, excavation protection, and communication around heavy equipment and active work zones.

Welding accounts for 6 questions. Candidates should understand pipe preparation, alignment, welding procedures, equipment, workmanship, and the purpose of producing sound pipeline connections.

Paving accounts for 5 questions. Pipeline and conduit projects frequently disturb streets, driveways, or other paved areas. Candidates should understand the general sequence of restoring excavated areas through backfill, compaction, base preparation, and asphalt placement.

Nevada One Call accounts for 3 questions. Underground utility awareness is a critical part of excavation work. Candidates should understand the importance of notification and utility marking before trenching or boring begins.

The NFPA 30 reference should be used throughout study sessions so candidates become comfortable with its physical organization. The more familiar the book becomes, the less time may be needed for lookups during the exam.

Begin by learning the table of contents and major topic areas. Then practice moving between the index, chapters, sections, and definitions to locate specific requirements.

One useful exercise is to create a list of common NFPA 30 topics and practice locating each one repeatedly. Candidates can track how long each search takes and focus additional practice on the slowest areas.

Practice questions should also be combined with code navigation. Attempt a question first from trade knowledge, decide whether NFPA 30 is needed, and then use the reference only when a code lookup adds value.

This method helps develop judgment. Some questions can be answered from technical understanding, while others may require confirmation of a specific code provision.

Candidates should also practice managing time. With 60 questions in two hours, spending excessive time on one reference search can affect the entire examination. Move past difficult questions when necessary and return later.

A project-sequence study method can help organize the broader A-19 material. Begin with Nevada One Call and site planning, move into excavation and trench protection, then review pipe materials, joining and welding, protection, backfill, compaction, and paving.

This sequence reflects the way underground pipeline and conduit projects progress in the field and can make the exam categories easier to connect.

Because this package contains only the exam-room-approved reference, candidates should make sure their broader study plan also covers the trade knowledge needed for gas piping, water piping, excavation, safety, welding, paving, and utility notification.
