1.2 Open-Book References, PDF Navigation & Calculator Rules

1.2 Open-Book References, PDF Navigation & Calculator Rules

Quick Answer: Level I is open book. You may use on-screen searchable PDFs and bound print copies of NFPA 13, 13D, 13R, and 291 — all 2022 editions. An NFPA Handbook is not accepted. Highlights and permanently attached tabs are allowed; handwritten notes and sticky notes are not. Only the built-in basic and scientific calculators are allowed — no personal calculators.

Open book on a NICET Water-Based Systems Layout exam does not mean you can wander through any fire-protection book until the clock dies. It means four named 2022 standards are in the room and on the screen, under strict physical-book rules, while the session still runs at about 85 seconds per item. This independent OpenExamPrep study guide treats reference navigation as a scored skill. The candidate who already knows that standard-spray spacing lives in NFPA 13 (2022) Chapter 10 will finish; the candidate who searches the word "sprinkler" and scrolls will not.

What you may use during the exam

The Level I Selected General References list (updated exams released July 8, 2024) is short on purpose.

NICET states that test questions are based on those editions, so bring 2022. You may bring older or newer editions at your own risk. If a table number moved between 2016 and 2022, the on-screen 2022 PDF is the safer lookup. The July 8, 2024 exam release is exactly this edition change: studying a 2016 spacing table is studying the wrong book.

NFPA Handbooks are not accepted as a substitute for any listed title. Handbook commentary, extra examples, and different pagination will get the print copy turned away at check-in. Buy or borrow the standard, not the handbook wrap.

Print copies must be bound or secured in a three-ring binder with a title page (NICET posts an example on the program page). You may use highlighted text and self-adhesive index tabs or dividers that are permanently attached. You may not add handwritten notes. Loose paper, loose pages, and freestanding tabs — including repositionable sticky notes of any kind — are not permitted in testing centers. OnVUE does not create a loophole: you may use only references approved for Level I, still without notes or extra screens.

Example: A candidate highlights Table 10.2.4.2.1 and affixes a plastic tab labeled "Spacing Ch 10" that cannot be peeled and moved during the exam. That book should be admitted. The same candidate who wrote "OH2 = 130 ft²" in the margin, or parked a yellow sticky on Chapter 19, is carrying a prohibited modification. Pearson VUE staff can stop the book at the locker, and you then sit an open-book exam with only the on-screen PDFs — still usable, but slower than the tab set you planned.

Study-only books that stay outside the room

The same reference PDF lists publications that can build job knowledge but are not permitted in the test center:

Those titles support Safety and "identify design standards" tasks, but you cannot open them during the CBT. If a question needs an OSHA rule or an IBC construction type, it is testing what you already studied, not a live lookup. Do not slide an OSHA pocket guide into the NFPA 13 binder; that is still an unauthorized insert.

How searchable PDFs change preparation

On-screen references are searchable PDFs. That is the largest prep change from a closed-book licensing exam and from older paper-only NICET sessions. Search is fast only when the query is specific:

• Search section and table numbers (10.2.4.2.1, 28.1) rather than vague words (spacing, plans).
• Reuse the occupancy name or sprinkler type the stem already used.
• If the occupancy is a one- or two-family dwelling, open 13D, not 13. If the stem is a hydrant residual and a pitot tube, open 291, not NFPA 13 Chapter 19.
• Expect many hits for deflector. Jump to Chapter 10 for standard-spray installation rather than reading Chapter 8 system types first.
• If a search returns annex material, prefer the enforceable body chapter the stem is asking you to apply, then use annex text only if you still need commentary — and remember the exam items are written to the 2022 standard, not a handbook essay.

Physical tabs still matter. The PDF search box does not replace muscle memory on:

• Chapter 10 — standard-spray spacing, maximum protection area, wall distance, and deflector position in unobstructed and obstructed construction. NFPA 13 (2022) Table 10.2.4.2.1 is the lookup most layout technicians mean when they say "the spacing table."
• Chapter 19 — occupancy-hazard density/area design approach: density, area of operation, and hose-stream allowances you will work in later hydraulics sections of this guide.
• Chapter 28 — working plans content that belongs in a submittal: what must appear on the drawings you assemble for a supervisor.

Also tab the table of contents, occupancy/hazard definitions, hanger spacing, and NFPA 291 hydrant-color and pitot-formula pages. Permanently attached tabs beat a perfect memory of a page number you will not have time to recall under 85 seconds.

Practice timed lookups. Sit with a lawfully obtained 2022 PDF and give yourself 80 seconds to find the maximum protection area for a stated sprinkler and hazard. If you cannot land on the table without reading two chapters, your tab set or search string is wrong — the open-book format is not a license to learn NFPA 13 for the first time in the Pearson VUE lobby.

Example: Stem: "For a hydraulically calculated light-hazard standard spray sprinkler under noncombustible unobstructed construction, what maximum protection area does NFPA 13 (2022) allow?" Do not invent a density and multiply. Open NFPA 13, go to Chapter 10, find Table 10.2.4.2.1(a). That lookup pattern is the exam skill. The printed cell is the authority; this overview does not replace the table with a memorized number.

Which book for which stem

Decide the document before you decide the chapter:

• NFPA 13 (2022) — commercial and most mixed occupancies: hazard, spacing, deflector, obstructions, pipe and hangers, density/area, working plans, and basic sprinkler discharge Q = K√P.
• NFPA 13D (2022) — one- and two-family dwellings and manufactured homes. Residential sprinkler listings, water-supply minimums, and coverage rules in 13D are not the 13 rules with a smaller building.
• NFPA 13R (2022) — low-rise residential occupancies. Do not apply 13R omission and square-footage rules to a 13 warehouse stem.
• NFPA 291 (2022) — hydrant flow tests, pitot readings, residual/static pressures, and hydrant marking colors. Layout hydraulics that start from a water-supply graph still live in 13; the flow-test recommended practice is 291.

If two books could apply, read the occupancy and the contract code summary in the stem first. Outline task 1.4.1 is exactly this choice: which standard did the specification name?

Calculator rules and what they imply for hydraulics

Both a basic calculator and a scientific calculator are built into the exam. Candidates may not bring any personal calculators into the testing room — not a phone, not a construction-site scientific, not a printing calculator. NICET points to a CBT Calculator Preview on the program site; use it before exam day so you are not discovering the square-root key during a pitot item.

Level I requires basic hydraulic equations. You will need square root and careful parentheses:

• Sprinkler discharge: Q = K√P (flow from K-factor and pressure).
• NFPA 291 (2022) Equation 4.9.3a pitot form: Q = 29.84 × c × d² × √p (coefficient, orifice diameter, pitot pressure). Compute diameter squared before multiplying through; do not take the square root of the entire product. Older pocket cards still print 29.83; that stale coefficient will miss the 2022 equation.
• Elevation head: 0.433 psi per foot of water (or 2.31 feet per psi) when a stem gives a riser height.

The scientific mode handles roots and exponents; the basic mode is faster for adding residual-pressure drops. You cannot store formulas or notes in the on-screen calculator. You cannot open a spreadsheet. Practice the algebra on a simple scientific so the keystrokes are boring. OnVUE is not an exception: Browser Lock still supplies only the built-in tools. A second monitor with Excel, or a handheld calculator just off camera, is a security violation, not a study hack.

A dual navigation plan for exam day

1. Before the appointment. Strip sticky notes. Remove loose inserts. Print NICET's title-page example and put it on each binder. Highlight tables you will actually open. Attach permanent tabs to NFPA 13 Chapters 10, 19, and 28, to 13D/13R scope chapters, and to NFPA 291 flow-test and marking sections.
2. During the tutorial. Confirm that on-screen PDFs open, search works, and both calculator modes load. That confirmation is why the extra 10 minutes exist.
3. During items. For a lookup, choose the document first (13 vs 13D vs 13R vs 291), then the chapter, then search a number. If search fails in about 20 seconds, jump to the tabbed print copy of the same chapter instead of scrolling.
4. If the print edition disagrees with the on-screen 2022 PDF. Trust the on-screen 2022 file; items were written to that edition. This is the practical reason NICET warns that older or newer print editions are at your own risk.

Open book rewards technicians who already work in the standards, not candidates who hope to read NFPA 13 for the first time after the NDA screen. Build lookup speed in this guide's later layout chapters; this section only installs the rules so those lookups are legal and fast.
