Introduction
The Virginia Department of Fire Programs (VDFP) Hazardous Materials
Awareness and Operations Certification Examination assesses a responder's
ability to recognize, evaluate, and respond safely to hazardous materials
incidents. The examination evaluates knowledge of hazard identification,
chemical and physical properties, DOT placarding, the Emergency Response
Guidebook, NFPA 470 standards, OSHA regulations, personal protective
equipment, decontamination procedures, and defensive tactical priorities.
Candidates are tested through multiple-choice and scenario-based questions
that emphasize real-world decision-making, safety, and the critical thinking
required to protect life, property, and the environment during hazardous
materials emergencies. A passing score demonstrates the competencies
necessary for certification.
,SECTION ONE: QUESTIONS 1–100
1. What is the primary mission of a first responder at a hazardous
materials incident?
A. To contain the release and clean up the spill
B. To identify the material and perform offensive mitigation
C. To protect life, the environment, and property, and to prevent the
spread of the incident
D. To conduct decontamination of all civilians
RATIONALE: The mission of the first responder at a hazmat incident is to
protect life, the environment, and property, and to prevent the spread of the
incident. Offensive mitigation is performed by hazardous materials
technicians.
2. What are the four main responsibilities of an Awareness level
responder?
A. Recognition, containment, decontamination, and termination
B. Recognition, isolation, protection, and notification
C. Identification, mitigation, recovery, and reporting
D. Assessment, rescue, treatment, and transport
RATIONALE: The Awareness level responder is trained to recognize the
presence of hazardous materials, isolate the area, protect themselves and
others, and notify the appropriate authorities.
3. What is the first priority at any hazardous materials incident?
A. Property conservation
B. Environmental protection
C. Evidence preservation
, D. Life safety
RATIONALE: Life safety is always the first priority at any emergency
incident, including hazardous materials incidents. Personal safety of
responders and the public takes precedence over property and environmental
concerns.
4. What does the acronym ERG stand for?
A. Emergency Rescue Guidelines
B. Environmental Response Guide
C. Emergency Response Guidebook
D. Emergency Radiation Guide
RATIONALE: The ERG is the Emergency Response Guidebook, a
reference document developed jointly by the United States, Canada, and
Mexico for first responders to hazardous materials transportation incidents.
5. What are the three main sections of the Emergency Response
Guidebook?
A. Red pages, blue pages, and green pages
B. White pages, yellow-bordered pages, and blue-bordered pages
C. Orange pages, green pages, and white pages
D. Yellow pages, red pages, and purple pages
RATIONALE: The ERG is organized into white pages (introductory and
instructional material), yellow-bordered pages (numerical index of UN/NA
identification numbers), and blue-bordered pages (alphabetical index of
material names).
6. What does the orange-bordered section of the ERG contain?
A. Initial isolation and protective action distances
, B. Numerical index of UN identification numbers
C. Guides for response actions, including potential hazards and public
safety recommendations
D. Alphabetical index of hazardous materials
RATIONALE: The orange-bordered section of the ERG contains the
numbered guides that provide safety recommendations, potential hazards,
and emergency response actions for each hazard class.
7. What does the green-bordered section of the ERG contain?
A. Response guides for all hazardous materials
B. Initial isolation and protective action distances for specific materials
C. Alphabetical index of chemical names
D. Numerical index of UN numbers
RATIONALE: The green-bordered pages contain Table 1 and Table 3,
which provide initial isolation and protective action distances for materials
that are toxic by inhalation (TIH) and materials that produce toxic gases when
reacting with water.
8. What does the acronym UN/NA stand for in the context of hazardous
materials?
A. Unified National / North American
B. United Nations / North American
C. Universal Number / National Association
D. Uniform Notation / Nuclear Agency
RATIONALE: UN/NA stands for United Nations / North American
identification number, a four-digit code assigned to hazardous materials for
identification during transportation.
