HAZMAT Technician Complete Study Review with Solutions
1. Acid - pH less than 7
- Reacts with bases and certain metals to form salts
- Turns blue litmus red
2. Caustic (Base) - pH greater than 7
- Reacts with acids and certain metals to form salts
3. Air Reactivity Materials that can react or ignite if they are exposed to air.
4. Auto-refrigera- A phenomenon that occurs during the rapid release (boiling) of a liquefied gas
tion 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.
5. Biological Agents Biological Agents include bacteria, viruses, fungi, other microorganisms and their
associated toxins. Many microbes reproduce rapidly and require minimal re-
sources for survival; therefore, they are a potential danger in a wide variety of
occupational settings.
6. 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: Attects human health in a variety of ways ranging from allergic reactions to
death.
7. Blood Agent A chemical compound, including the cyanide group, which attects 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 attect the
blood in any way.

8. 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.
9. Catalyst a substance that accelerates the rate of a chemical reaction without itself changing.
10. Chemical Change Changes that take place on the molecular level. A chemical change produces a new
substance.
11. Chemical Interac- Caused when two or more chemicals, or the chemical and its container are incom-
tions patible.
12. Compound Mix- Separate elements that bond together to form compound mixture, they have a
ture tendency to break down into their component parts, sometimes in an explosive
manner.
13. Concentration When dealing with corrosives, the amount of acid or base is compared to the
amount of water present.
14. Critical Tempera- the temperature above which gas cannot be liquefied no matter what pressure is
ture applied.
15. critical pressure The pressure that must be applied to bring a gas to its liquid state.
16. Dissociation The separation of a substance into two or more simpler substances, or of a
molecule into atoms or ions by the action of heat or a chemical process. Usually
reversible.
17. Corrosive A measure of a substance's tendency to deteriorate in the presence of another
substance or in a particular environment.
18. Dose The concentration or amount of material to which the body is exposed over a
specific time period
