HAZMAT Technician) Questions and
Answers Exam
Acid - ANSWER>>- pH less than 7
- Reacts with bases and certain metals to form salts
- Turns blue litmus red
Caustic (Base) - ANSWER>>- pH greater than 7
- Reacts with acids and certain metals to form salts
Air Reactivity - ANSWER>>Materials that can react or ignite if they are exposed to
air.
Auto-refrigeration - ANSWER>>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 - ANSWER>>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 - ANSWER>>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 - ANSWER>>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 - ANSWER>>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 - ANSWER>>a substance that accelerates the rate of a chemical reaction
without itself changing.
Chemical Change - ANSWER>>Changes that take place on the molecular level. A
chemical change produces a new substance.
Chemical Interactions - ANSWER>>Caused when two or more chemicals, or the
chemical and its container are incompatible.
Compound Mixture - ANSWER>>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 - ANSWER>>When dealing with corrosives, the amount of acid or
base is compared to the amount of water present.
