Introduction
This examination assesses the candidate's knowledge and skills required for certification as a
Hazardous Materials Operations level responder under NFPA 470 and TCFP standards. It evaluates
competency in analyzing hazardous materials incidents, planning and implementing defensive
responses, selecting appropriate personal protective equipment, performing decontamination, and
complying with OSHA and DOT regulations. The test utilizes multiple-choice and scenario-based
questions designed to mirror real-world emergency response situations. Emphasis is placed on the
,application of defensive tactics, risk-based decision-making, and the safe management of
hazardous materials incidents to protect responders, the public, and the environment.
SECTION ONE: QUESTIONS 1–100
Question 1
An operations-level responder arrives at a motor vehicle accident and observes an overturned
tanker truck displaying a placard with the number 3 in the lower corner and a flame symbol. The
driver is unresponsive near the cab. What is the responder's priority action?
A. Approach the cab to extract the driver before the tanker ignites.
B. Establish an initial isolation zone, identify the material from a safe distance, and notify
additional resources.
C. Use a thermal imaging camera to check the tanker's temperature before evacuating.
D. Deploy a foam blanket on the tanker immediately to prevent ignition.
🟢 B. Establish an initial isolation zone, identify the material from a safe distance, and notify
additional resources.
🔴 RATIONALE: Operations-level responders must take defensive actions at a safe distance. The
placard indicates a Class 3 flammable liquid. The responder must establish isolation, attempt
identification from a safe location, and request additional resources. Approaching the vehicle to
extract the driver would violate safe-distance protocols and expose the responder to fire and
chemical hazards.
,Question 2
An operations-level responder is directed to establish a decontamination corridor at a hazardous
materials incident. Which zone should the decontamination corridor be located in?
A. The hot zone, to begin decontamination immediately at the point of release.
B. The warm zone, to serve as a transition between the hot and cold zones.
C. The cold zone, to ensure decontamination occurs far from the hazard.
D. The command post, to allow the incident commander to observe decontamination.
🟢 B. The warm zone, to serve as a transition between the hot and cold zones.
🔴 RATIONALE: The decontamination corridor is established in the warm zone, which serves as
the transition area between the hot zone (contaminated area) and the cold zone (clean area).
This placement allows responders to remove contaminants before entering the cold zone and
prevents cross-contamination.
Question 3
An operations-level responder is reviewing the Emergency Response Guidebook for a material
with UN identification number 1203. Which section of the ERG should be consulted first to
determine the appropriate guide number?
A. The white pages, which list the material by name.
B. The yellow-bordered pages, which list the material by UN identification number.
, C. The blue-bordered pages, which list the material by name.
D. The green-bordered pages, which provide isolation distances.
🟢 B. The yellow-bordered pages, which list the material by UN identification number.
🔴 RATIONALE: The yellow-bordered pages of the ERG are indexed by UN/NA identification
numbers. When a responder has the UN number from a placard, label, or shipping paper, the
yellow pages provide the corresponding guide number for that material.
Question 4
During a hazardous materials incident involving an unknown material, the incident commander
asks the operations-level responder to estimate the potential harm using the TRACE-MP
framework. Which of the following represents the "T" in TRACE-MP?
A. Toxicological exposure assessment.
B. Thermal hazards.
C. Transport and storage risks.
D. Terrain and topography concerns.
🟢 B. Thermal hazards.
🔴 RATIONALE: TRACE-MP is a memory aid used to identify potential hazards. The letters stand
for Thermal, Radiation, Asphyxiation, Chemical, Etiological, Mechanical, and Psychological. The
"T" represents thermal hazards, including fire and heat exposure.
