The NFPA 470 Hazmat Incident Commander exam consists of 50-100 multiple-choice questions covering Chapter 12 IC JPRs. You have about 2 hours and need 70% to pass. The exam covers incident command (Unified Command, ICS Type 2/3, hazmat branch director), risk-based response (GEDAPER), resource coordination (hazmat team, mutual aid, CHEMTREC 800-424-9300, EPA NRC 800-424-8802), action planning (ICS-201/202/204), termination (debrief, PIA, critique, exposure documentation), federal/state regulations (CERCLA, EPCRA, RCRA, HAZWOPER), and high-risk scenarios (rail-car, tank truck, pipeline, WMD/CBRN).

1Under NFPA 470 Chapter 12, which incident management structure is the standard for a hazardous materials release that involves fire, EMS, law enforcement, and an environmental agency with overlapping statutory authority?
2A working hazmat release expands from a single jurisdiction to a multi-county event requiring a written IAP, an operational period plan, and additional command/general staff. What ICS incident type best describes this complexity?
3Within the ICS organization at a Type 2 hazmat incident, who reports directly to the Operations Section Chief and manages all tactical hazmat resources?
4Per NFPA 470 Chapter 12 JPRs, what is the IC's first command priority upon assuming command of a hazmat incident?
5An IC at a chlorine rail-car release establishes a Hazmat Group instead of a Branch. Which condition most appropriately supports using a Group rather than a Branch?
6The Hazmat IC is asked which ICS position is responsible for keeping the IC informed of safety-related issues and has the authority to stop unsafe acts immediately. Which position fits?
7Under Unified Command at a hazmat incident, who develops a single set of incident objectives?
8Which ICS staff position serves as the on-scene point of contact for assisting agencies and stakeholders such as the responsible party, public works, and federal regulators?
9At a hazmat incident, when must the IC formally transfer command per NFPA 470 expectations?
10Span of control under NFPA/ICS guidelines is generally considered optimal at what ratio?

Frequently Asked Questions
What is the NFPA 470 Hazmat Incident Commander certification?
NFPA 470 is the consolidated standard for hazardous materials/WMD emergency response personnel, replacing NFPA 472, 473, and 1072. Chapter 12 defines the Incident Commander JPRs covering command, action planning, resource coordination, and termination of hazmat incidents. Pro Board and IFSAC accredit agencies that certify at this level.
What is the exam format and passing score?
The written exam typically contains 50-100 multiple-choice questions and runs about 2 hours, with a 70% passing score. A practical skills evaluation is administered separately. The exact length and fee depend on the Pro Board or IFSAC accredited agency.
What is the GEDAPER process?
GEDAPER is a risk-based response model the hazmat IC uses to make decisions: Gather information, Estimate course and harm, Determine strategic goals, Assess tactical options and resources, Plan and implement, Evaluate, and Review. It frames every size-up and IAP at hazmat incidents.
When do I notify CHEMTREC and the EPA National Response Center?
CHEMTREC (800-424-9300) provides 24/7 technical product information for chemical incidents and shipper contact. The EPA National Response Center (800-424-8802) is the federal point of contact for reporting oil and chemical releases that meet reportable quantities under CERCLA and the Clean Water Act.
Which ICS forms does the Hazmat IC use most?
ICS-201 captures size-up and initial incident briefing, ICS-202 documents incident objectives, ICS-204 assigns tactical resources to divisions/groups, and ICS-205 covers communications. The IC uses these to build and document the Incident Action Plan.
What regulations does the Hazmat IC need to know?
Core regulations include OSHA 29 CFR 1910.120 (HAZWOPER), CERCLA (Superfund) reporting, EPCRA Tier II reporting and LEPC notification, RCRA for hazardous waste, and DOT/PHMSA placarding and shipping paper rules referenced through the Emergency Response Guidebook.
What is required to terminate a hazmat incident?
Termination includes on-scene debriefing of responders, post-incident analysis (PIA), formal critique, documentation of exposures and injuries, decontamination verification, and transfer of the scene to the responsible party or cleanup contractor with appropriate documentation.
How is Unified Command used at hazmat incidents?
Unified Command brings together agencies with statutory authority (fire, EMS, law enforcement, environmental, federal on-scene coordinator) under a single IAP without surrendering authority. It is the standard structure for multi-jurisdictional hazmat incidents and ICS Type 2/3 events.
