QUESTIONS WITH ANSWERS GRADED A+
●● HAZMAT Technician Additional Training.
Answer: Occupational Safety and Health Administration (OSHA)
●● HAZMAT Technician Goals.
Answer: *ANALYZE* incident
*PLAN* response
*IMPLEMENT* planned response
*EVALUATE* progress
*TERMINATE* incident
●● Acid.
Answer: pH less than 7. Turns blue litmus red, sour taste, and reacts with
bases.
●● Caustic.
Answer: pH greater than 7. Capable of burning / corroding / dissolving /
eating away by chemical action.
●● Air-Reactivity.
,Answer: Materials that can react / ignite when exposed to air (ex:
phosphorus)
●● Auto-Refrigeration.
Answer: Phenomenon that occurs during rapid release (boiling) of a
liquefied gas that causes it to temporarily remain in a liquid state
through rapid cooling.
●● Biological Agents.
Answer: Bacteria, viruses, fungi, and other microorganisms and all
associated toxins. Reproduce rapidly and require minimal resource for
survival.
●● Blood Agents.
Answer: Chemical compound (including cyanide) which prevents
normal utilization of blood by body tissues. Does not actually affect
blood itself.
●● Boiling Point.
Answer: *Temperature at which transition from liquid to gas state
occurs.* At this temperature, the vapor pressure of a liquid equals
surrounding atmospheric pressure, so liquid rapidly becomes a vapor.
●● Catalyst.
,Answer: Substance that initiates or accelerates a chemical reaction
without itself being affected.
●● Chemical Change.
Answer: Change that takes place on *molecular level, which 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. Tendency to break down
into their component parts, sometimes explosively.
●● Concentration.
Answer: Amount of acid or base compared to the amount of water
present (relating to corrosives)
●● Critical Temperature.
Answer: Minimum temperature at which a gas can be liquefied, no
matter how much pressure is applied. *A gas cannot be liquefied above
its critical temperature.*
, ●● Critical Pressure.
Answer: The pressure that must be applied to bring a gas to its liquid
state
●● Corrosive (acids / bases).
Answer: Measure of a substance's tendency to deteriorate in the presence
of another substance or in a particular environment.
●● Dose.
Answer: Concentration or amount of material to which the body is
exposed over a specific time period.
●● Dose Response.
Answer: The biological reaction caused by the dose in the body. Degree
of harm is directly related to dose (time and amount) and its impact on
bodily functions.
●● Expansion Ratio.
Answer: Amount of gas produced by a given volume of liquid at a given
temperature
*560 : 1445*
●● Flash Point.
