About HAZMAT First Responder Operations (FRO) Test
The HAZMAT First Responder Operations (FRO) test is a requirement for anyone who wants to become a HAZMAT First Responder.
The test is designed to assess the knowledge and skills of individuals who respond to releases or potential releases of hazardous substances as part of the initial response to the site for the purpose of protecting nearby persons, property, or the environment from the effects of the release.
The test covers a wide range of topics, including:
- Hazard identification and classification
- Decontamination procedures
- Emergency response planning
- Personal protective equipment (PPE)
- Spill containment and control
To pass the HAZMAT FRO test, you must score a minimum of 70% on each of the five modules.
The test is administered by the National Registry of Emergency Medical Technicians (NREMT).
Applicants must meet certain eligibility requirements, including having a high school diploma or equivalent, completing a HAZMAT First Responder training program, and passing the NREMT First Responder exam.
The NREMT offers practice tests online and in books.
Applicants can study for the HAZMAT FRO test by reviewing the OSHA Hazardous Materials Emergency Response Standard (29 CFR 1910.120), the Emergency Response Guidebook (ERG), and the U.S.
Department of Transportation (DOT) Emergency Response Guide for Shippers and Transporters.
Additionally, many online resources and practice tests are available to help applicants prepare for the exam.
Here are some additional study tips for the HAZMAT FRO test:
- Form a study group with other HAZMAT First Responder students
- Ask your instructor for help with any topics that you are struggling with
- Take advantage of the many online resources that are available
- Get a good night’s sleep before the test
- Eat a healthy breakfast on the day of the test
- Arrive at the testing site early
- Relax and do your best!
