HAZMAT AWARENESS BUNDLED EXAM 2
CERTIFICATION ASSESSMENT 2026 VERIFIED
ANSWERS GRADED A+
◉ In what NFPA/EPA level of response can the incident be
controlled by the initial responding units?
Answer: Level 1
◉ In what NFPA/EPA level of response there is moderate incident
that encompasses a greater potential threat to the surrounding area
or community? Could possibly require evacuation.
Answer: Level 2
◉ In what NFPA/EPA level of response there is a major incident with
extreme hazards over large geographic zones. These incidents
typically require intervention of multiple resource agencies.
Answer: Level 3
◉ What is a boiling liquid/expanding vapor explosion; an explosion
that occurs when pressurized liquefied materials inside a closed
vessel are exposed to a source of high heat?
Answer: BLEVE
,◉ What is the temperature when a liquid changes its phase into a
vapor or gas?
Answer: Boiling point
◉ What is the ability of a chemical to undergo an alteration in its
chemical make-up, usually accompanied by a release of some form of
energy?
Answer: Chemical reactivity
◉ What is the combined process of emission, transmission, and
absorption of energy traveling by electromagnetic wave propagation
between a region of higher temperature and a region of lower
temperature?
Answer: Radiation
◉ What is an expression of a fuel/air mixture, defined by upper and
lower limits, that reflects an amount of flammable vapor mixed with
a given volume of air?
Answer: Flammable Range
◉ What is the minimum temperature at which a liquid or a solid
releases sufficient vapor to form an ignitable mixture with air?
Answer: Flash point
, ◉ What is the minimum temp required to cause self-sustained
combustion in absence of any source of ignition?
Answer: Ignition/Autoignition
◉ What refers to solids and is usually expressed in microns or
percent passing through a meshed screen?
Answer: Particle Size
◉ What is the length of time a chemical agent stays as a liquid?
Answer: Persistence
◉ What type of chemicals are typically dense, oily substances with
high molecular weights and low vapor pressures?
Answer: Persistent chemicals
◉ What is the condition in which matter exists under specified
kinetic conditions?
Answer: Physical state
◉ What is it when the weight of a substance or material is compared
with the weight of an equal volume of water?
Answer: Specific Gravity
