About the Hazmat Operations Exam
The NFPA 470 Hazardous Materials Operations certification validates defensive response competency for first responders who arrive on scene of a hazmat or WMD incident. Operations-level responders work outside the hot zone to protect nearby persons, the environment, and property. The exam covers defensive operations (isolation, damming/diking/diverting, vapor suppression and dispersion), EPA PPE Levels A-D, gross/technical/mass decontamination, ICS for hazmat, detection and monitoring instruments, product control, and Chapter 9 mission-specific specialties.

How do the Hazmat Ops vocabulary games work?
There are 4 games built on 20 Hazmat Ops terms. In Guess the Term, a clue describes one term and you have six tries to spell it, with green, yellow and gray letters showing how close you are. In Term Match, six terms appear as colored tiles; swap neighbors to line up three or more of the same term, and each match shows what the term means. In Term Pairs, twelve face-down cards hide six pairs of terms; flip two at a time to find each pair, and every pair you find shows what the term means. In Term Search, five terms hide in a grid of letters, reading across, down or diagonally; drag across a term to circle it, and each term you find shows what it means.
Where do the Hazmat Ops terms come from?
OpenExamPrep researched each term from the NFPA 470 — Pro Board / IFSAC content outline and primary sources, listed under Sources on this page. The game is independent study material, not an official exam resource.
What is the NFPA 470 Hazmat Operations certification?
NFPA 470 Hazardous Materials Operations certifies first responders to perform defensive actions at hazmat or WMD incidents. Operations responders isolate the scene, protect exposures, and contain releases from a safe distance — they do not approach the point of release. NFPA 470 consolidates the former NFPA 472, 473, and 1072 standards and is accredited through Pro Board and IFSAC.
What is the format of the Hazmat Operations exam?
There is no national written form. Each Pro Board or IFSAC certifying entity sets its own exam: Kansas, Missouri and the New Brunswick FCPNB use 100 multiple-choice questions with a 70% pass mark, and Kansas and Missouri allow 2 hours. Core competencies (NFPA 470 Chapter 7) are usually tested together with the mission-specific competencies (Chapter 9) the jurisdiction requires, and skills are evaluated pass/fail.
