HAZMAT Technician Exam Questions and
Answers 100% Pass
Acid - ✔✔- pH less than 7
- Reacts with bases and certain metals to form salts
- Turns blue litmus red
Caustic (Base) - ✔✔- pH greater than 7
- Reacts with acids and certain metals to form salts
Air Reactivity - ✔✔Materials that can react or ignite if they are exposed to air.
Auto-refrigeration - ✔✔A phenomenon that occurs during the rapid release (boiling) of a liquefied gas
that causes it to temporarily remain in a liquid state through rapid cooling.
RISK: False assumption of product elimination until the product resumes boiling and subsequent release.
Biological Agents - ✔✔Biological Agents include bacteria, viruses, fungi, other microorganisms and their
associated toxins. Many microbes reproduce rapidly and require minimal resources for survival;
therefore, they are a potential danger in a wide variety of occupational settings.

, Biological Toxins - ✔✔Toxins can be small molecules, peptides, or proteins that are capable of causing
disease on contact with or absorption by body tissues.
RISK: Affects human health in a variety of ways ranging from allergic reactions to death.
Blood Agent - ✔✔A chemical compound, including the cyanide group, which affects bodily functions by
preventing the normal utilization of oxygen by body tissues. The term "blood agent" is a misnomer,
however, because these agents do not actually affect the blood in any way.
Boiling Point - ✔✔Temperature at which the transition from a liquid to a gas state occurs. At this
temperature, the vapor pressure of a liquid equals the surrounding atmospheric pressure so that the
liquid rapidly becomes a vapor.
Catalyst - ✔✔a substance that accelerates the rate of a chemical reaction without itself changing.
Chemical Change - ✔✔Changes that take place on the molecular level. A chemical change produces a
new substance.
Chemical Interactions - ✔✔Caused when two or more chemicals, or the chemical and its container are
incompatible.
Compound Mixture - ✔✔Separate elements that bond together to form compound mixture, they have a
tendency to break down into their component parts, sometimes in an explosive manner.
Concentration - ✔✔When dealing with corrosives, the amount of acid or base is compared to the amount
of water present.
Critical Temperature - ✔✔the temperature above which gas cannot be liquefied no matter what pressure
is applied.
critical pressure - ✔✔The pressure that must be applied to bring a gas to its liquid state.
