NICET CPD

As of March 12, 2026, NICET still lists the current SHS exams at 83 questions in 140 minutes for Level I, 144 questions in 165 minutes for Level II, 94 questions in 170 minutes for Level III, and 63 questions in 280 minutes for Level IV. NICET also states on the SHS program page that updated exams will be available in Fall 2026: Level I moves to 91 questions in 141 minutes, Level II to 109 questions in 154 minutes, Level III to 113 questions in 169 minutes, and Level IV to 99 questions in 289 minutes with a scheduled 30-minute break. The current live references page still lists older NFPA editions for SHS, so candidates in 2026 need to track whether they are preparing for the current exam version or the Fall 2026 update.

NICET Special Hazards Study Tips from Top Performers

1Study by workflow instead of by agent only: inspection, disablement, testing, recharge, commissioning, and documentation are the actions the SHS outlines repeatedly emphasize.
2Build a clean mental map of system families such as clean agent, CO2, foam, dry chemical, wet chemical, and water mist so you can recognize where their hazards and components differ.
3Practice reading sequence-of-operations matrices and turning them into actual detector, releasing, abort, notification, and shutdown behavior.
4Do repeated room-integrity, piping, and device-layout scenarios because SHS questions often hinge on what the enclosure or hazard really needs, not just a memorized definition.
5Use the current references page as your study anchor today, but keep watching the SHS program page because NICET has already posted a Fall 2026 transition notice.
6Drill cylinder, hose, pressure, hydrotest, and recharge concepts until you can separate field inspection tasks from service-center or regulated recharge steps.
7Treat Level III and IV content as management-heavy technical work: submittals, training, acceptance planning, budgets, contracts, and AHJ coordination matter more than many candidates expect.
8Run mixed timed sets after each topic block so code navigation, troubleshooting, safety judgment, and design reasoning improve together.
