Question 1
Which of the following best describes the primary role of a responder trained to the
Hazardous Materials Awareness level?
A) To respond to releases for the purpose of plugging, patching, or stopping the release.
B) To recognize the presence of hazardous materials, protect themselves, isolate the area, and
notify appropriate authorities.
C) To assume command of the incident and direct the remediation of the hazardous substance.
D) To perform defensive actions such as diking and damming to protect the environment.
E) To enter the hot zone to rescue victims and perform decontamination.
Correct Answer: B) To recognize the presence of hazardous materials, protect themselves,
isolate the area, and notify appropriate authorities.
Rationale: According to the provided text, the Awareness level is the lowest level of training.
These personnel are expected to recognize the presence or potential presence of hazardous
materials, identify the container or material if possible, transfer information to the
appropriate authority, and call for help. Crucially, they identify actions to protect themselves
and establish control by isolating the hazardous area and denying entry.
Question 2
Responders trained to the Operations level are expected to take which of the following
actions during a hazardous materials release?
A) Offensive actions to stop the release at its source.
B) Defensive actions to protect individuals, the environment, and property from the effects of
the release.
C) Remediation actions to clean up the spill after the emergency is over.
D) Specialized actions involving advanced monitoring and detection inside the hot zone.
E) Command actions to unilaterally terminate the incident without further support.
Correct Answer: B) Defensive actions to protect individuals, the environment, and property
from the effects of the release.
Rationale: The text defines Operations level responders as individuals who respond to
releases as part of their normal duties. They are expected to act in a defensive manner to
protect people, property, and the environment (e.g., diking, damming) but are not trained to
stop the release offensively.
Question 3
Which type of radiation is characterized as being stopped by the skin?
A) Beta radiation
, 2
B) Gamma radiation
C) Neutron radiation
D) Alpha radiation
E) X-ray radiation
Correct Answer: D) Alpha radiation
Rationale: The provided text explicitly states that Alpha radiation is stopped by the skin.
While it can be dangerous if ingested or inhaled, it lacks the penetrating power to pass
through the outer layer of skin.
• Option A: Beta radiation is stopped by clothing.
• Option B: Gamma radiation can pass completely through the human body.
Question 4
A chemical process that occurs when a substance combines with oxygen is defined as:
A) Polymerization
B) Oxidation
C) Cryogenic expansion
D) Systemic effect
E) Asphyxiation
Correct Answer: B) Oxidation
Rationale: Oxidation is defined in your text as the chemical process that occurs when a
substance combines with oxygen. This reaction can often result in fire or rust depending on
the speed and material involved.
Question 5
What is the defining temperature characteristic of a Cryogen (refrigerated liquid)?
A) A liquid that boils at 32°F.
B) A gas that turns to liquid at 0°F.
C) A substance that exists as a liquid at or below -130°F.
D) A substance that freezes at -40°F.
E) A liquid that is stored above 100°F.
Correct Answer: C) A substance that exists as a liquid at or below -130°F.
Rationale: The text defines a Cryogen as a refrigerated liquid that requires a temperature of -
130°F (negative 130 degrees Fahrenheit) or lower to maintain its liquid state.
Question 6
Which of the following describes a "Systemic effect" of a toxic material?
, 3
A) Damage limited to the specific area of contact, such as a chemical burn on the hand.
B) Temporary inflammation of the eyes or throat.
C) An effect that impacts the entire body system rather than a single location.
D) A reaction caused solely by the anxiety of the incident.
E) A physical injury resulting from the explosion of a container.
Correct Answer: C) An effect that impacts the entire body system rather than a single location.
Rationale: A systemic effect is defined as something that affects the entire system (body)
rather than a single location or entity. This contrasts with local effects, which are limited to
the point of contact.
Question 7
According to the Department of Transportation (DOT), "Bulk Packaging" for liquids involves a
maximum capacity greater than:
A) 55 gallons
B) 100 gallons
C) 119 gallons
D) 450 gallons
E) 882 gallons
Correct Answer: C) 119 gallons
Rationale: The text defines Bulk Packaging as a vessel or container in which hazardous
materials are loaded with a maximum capacity greater than 119 gallons (or 450 Liters) for
liquids. It also cites a net mass greater than 882 pounds for solids and a water capacity greater
than 1000 pounds for gases.
Question 8
You observe a rail car with a cylindrical tank and rounded ends. It has a single protective
housing on top for fittings and no bottom unloading piping. The pressure is likely greater than
25 psi. What type of rail car is this?
A) Low pressure tank car
B) Pressure tank car
C) Cryogenic tank car
D) Hopper car
E) Box car
Correct Answer: B) Pressure tank car
Rationale: Pressure tank cars are described as cylindrical tanks with rounded ends (heads).
They operate at pressures greater than 25 psi (typically 100 to 600 psi) and are used to
