Philadelphia Pennsylvania Engineer Grade D (ICC - 328_PA_PH) Exam Book Package

Philadelphia Pennsylvania Engineer Grade D (ICC - 328_PA_PH) Exam Book Package

If you’re preparing for the Pennsylvania (Philadelphia) Engineer Grade D (Fireman) exam through ICC, the right reference book matters—especially when the exam is open book and time moves fast. This Exam Book Package is built around a core operating-engineer text used to strengthen the everyday knowledge the Grade D exam expects: safe boiler operation, boiler fittings, feedwater and steam systems, draft, water treatment, and jobsite safety practices.

Whether you’re stepping into the role for the first time or you’ve been around boiler rooms for years, success on an open-book trade exam comes from knowing where the answers live and how the systems work together. That’s why this package focuses on a single, industry-recognized boiler operations reference you can study, tab, and practice with—so you spend less time hunting and more time answering with confidence.

Important note about editions: The ICC Philadelphia Contractor/Trades Examination Information Bulletin (published March 15, 2026) lists Low Pressure Boilers, 3rd Edition (ATP) as the reference for exam 328 (Engineer Grade D). This package includes Low Pressure Boilers, 5th Edition as your study book. Many candidates prefer newer editions for learning and review, but always rely on the currently approved reference list and edition rules shown in your ICC exam catalog/bulletin when you test.

Exam Details

• Exam: 328 Pennsylvania (Philadelphia) Engineer Grade D (Fireman)
• Exam format: Multiple-choice
• Number of questions: 50
• Time limit: 2.5 hours
• Testing: Pearson VUE (ICC Contractor/Trades program)
• Book status: Open book

The Grade D content areas shown in the ICC Philadelphia bulletin emphasize practical boiler-room competence and safety-driven decision-making. The bulletin’s content weighting for the 328 exam is organized around:

• Boiler Operations (20%)
• Boiler Fittings (10%)
• Feedwater Systems (20%)
• Steam System (20%)
• Draft System (4%)
• Boiler Water Treatment (6%)
• Boiler Operation Safety (20%)

In other words: you’re not only being tested on definitions. You’re being tested on how a working system behaves, how components protect equipment and people, and how to recognize and respond to operating conditions in a safe, professional way.

Open Book Test

The 328_PA_PH Engineer Grade D exam is listed as an open book exam in the ICC Philadelphia bulletin. Open book doesn’t mean “easy”—it means the exam rewards candidates who can navigate the reference efficiently and who understand the underlying boiler-room concepts well enough to confirm details quickly.

To make open-book testing work for you, focus on:

• Fast navigation: Build familiarity with chapter layout, headings, common tables, and recurring safety callouts.
• Smart tabbing: Mark the sections you repeatedly return to—startup/shutdown, operating limits, burner controls, draft/combustion basics, water level, and safety devices.
• Practice under time: Answer questions with a timer running so you learn when to look up and when to rely on trained knowledge.
• System thinking: Many questions are easier when you understand how feedwater, steam distribution, and draft/combustion interact.

Licensing Steps

Philadelphia issues Engineer Licenses in multiple grades, and the Grade D license is identified by the City as Firefighters only. The City’s licensing guidance states that applicants must have proof of successful completion of the Philadelphia Engineer examination of the appropriate grade.

Because licensing requirements can involve steps beyond the exam (and can change), a practical, exam-first approach looks like this:

1. Confirm your correct grade: Verify that Grade D (Fireman) is the license you need for the work you will perform in Philadelphia.
2. Register and schedule: Schedule the ICC Contractor/Trades exam through Pearson VUE using the ICC exam catalog for the 328_PA_PH listing.
3. Study with intent: Use your reference to build both concept knowledge and navigation speed—especially for safety and operating procedures.
4. Take the exam: Plan your pacing so you complete all questions and still have time to review flagged items.
5. Keep your passing documentation: Retain proof of successful completion for your license application steps with the City.

State Requirements

This exam is used for the City of Philadelphia Engineer Grade D licensing path. Philadelphia’s Engineer Licenses are classified into grades, and the City’s guidance identifies Grade D as Firefighters only. The City also indicates that candidates must provide proof of certification showing successful completion of the appropriate Philadelphia Engineer examination.

Beyond that proof-of-exam requirement, jurisdictions may have additional administrative requirements (forms, identification, or other local conditions). Keep your application steps aligned with the City of Philadelphia’s current Engineer License instructions.

Reference Books

• Low Pressure Boilers, 5th Edition
  A comprehensive boiler-operations text focused on safe and efficient operation of low pressure steam and hot water boilers, cooling systems, and related equipment. It’s widely used for training and exam preparation and includes practical coverage that supports day-to-day operating decisions in the boiler room.

This book is especially helpful for Grade D study because it supports the core knowledge areas that commonly show up in fireman/boiler operator testing:

• Boiler fundamentals: Types of low pressure boilers, heat transfer basics, steam fundamentals, and operating considerations.
• Controls and safety devices: Low-water cutoffs, pressure controls, relief valves, gauge glass use, and the intent behind safety interlocks.
• Combustion and draft awareness: Understanding what stable firing looks like, what draft does, and how poor combustion impacts safety and performance.
• Feedwater and steam systems: Condensate return, feedwater components, and how system conditions affect water level and pressure stability.
• Water treatment basics: Common water-side issues, what treatment is intended to prevent, and how to recognize early warning signs.
• Operating procedures: Startup, normal operations, shutdown, and safety-first responses to abnormal conditions.

Test Information and Study Materials

Because the 328 exam is weighted heavily toward operations and safety, your study plan should mirror that structure. A strong preparation routine often includes:

• Daily “systems review”: Spend time tracing the path of water → steam → distribution → condensate return, and identify where fittings and controls protect the system.
• Safety-first drilling: Practice questions and scenarios centered on low-water conditions, pressure control, abnormal firing, and safe response steps.
• Fittings mastery: Know the purpose and typical placement of key valves, check devices, gauges, and safety accessories. Many missed questions come from confusing component function.
• Water level discipline: Water level awareness is foundational—study normal level behavior, causes of level instability, and the safest corrective actions.
• Water treatment and blowdown awareness: Understand the “why” behind treatment and blowdown, and what symptoms suggest water quality problems.
• Timed practice: With 50 questions in 2.5 hours, you have about 3 minutes per question on average. Build confidence answering quickly and accurately.

If you’re tabbing your book for exam day, prioritize sections aligned to the bulletin’s higher-weight content areas: operations and safety, steam and feedwater systems, and the fittings that protect the boiler and the operator.
