QUESTION 1.
,A highway patrol officer arrives first at a traffic collision involving a tanker
truck displaying an unfamiliar hazard placard. A strong chemical odor is
present, and one motorist is requesting immediate rescue from a nearby
vehicle. What action is most consistent with hazardous materials awareness-
level responsibilities?
A. Immediately enter the hazard area to rescue the trapped motorist.
B. Establish isolation, remain uphill and upwind when feasible, notify
appropriate resources, and prevent additional exposures.
C. Open the tanker valves to determine whether pressure is building.
D. Direct nearby civilians to approach the tanker to identify the leaking
substance.
Correct Answer: B. Establish isolation, remain uphill and upwind when
feasible, notify appropriate resources, and prevent additional
exposures.
Explanation: Awareness-level responders are expected to recognize
hazardous materials incidents, protect themselves and others, establish
scene control, and initiate notifications rather than intervene directly.
Entering the hazard area or manipulating containers exceeds awareness-
level responsibilities and may significantly increase risk.

QUESTION 2.
During an initial size-up, several victims have collapsed near an overturned
cargo container with no visible fire. Which observation most strongly
indicates that responders should suspect a hazardous materials release?
A. The roadway is partially blocked.
,B. Victims exhibit similar unexplained symptoms after being in the same
area.
C. The incident occurred during daylight hours.
D. Traffic congestion has developed.
Correct Answer: B. Victims exhibit similar unexplained symptoms after
being in the same area.
Explanation: Multiple victims displaying similar unexplained medical
symptoms in a common location are a classic indicator of a hazardous
materials incident. The remaining choices may occur during many routine
emergencies and do not independently suggest hazardous materials
involvement.
────────────────────────────────────────
QUESTION 3.
Which document is specifically intended to help responders identify initial
isolation distances and recommended protective actions during the early
stages of a hazardous materials incident?
A. National Electrical Code
B. Highway Capacity Manual
C. Emergency Response Guidebook (ERG)
D. Building maintenance log
Correct Answer: C. Emergency Response Guidebook (ERG).
Explanation: The Emergency Response Guidebook provides initial guidance
for identifying hazards, establishing isolation distances, and selecting
protective actions during the first phase of a hazardous materials incident.
, The other documents are not designed for emergency hazardous materials
response.
────────────────────────────────────────
QUESTION 4.
A warehouse employee provides a Safety Data Sheet for a leaking product.
Before entering the area, the awareness-level responder should primarily use
the document to:
A. Determine whether specialized response resources may be needed.
B. Decide how to repair the leaking container.
C. Authorize unrestricted public access.
D. Develop long-term environmental remediation plans.
Correct Answer: A. Determine whether specialized response resources
may be needed.
Explanation: A Safety Data Sheet provides information about hazards,
protective measures, and emergency considerations that can assist
responders in recognizing risks and communicating accurate information.
Repairing containers and conducting remediation exceed awareness-level
responsibilities.
────────────────────────────────────────
QUESTION 5.
An incident commander requests information regarding the location of
shipping papers for a commercial motor vehicle transporting hazardous
materials. Where are these documents most commonly maintained during
transport?
