Hazmat Tech I Questions and Answers
Analyze the incident
Ans: Survey collect describe predict estimate
Plan the response
Ans: Identify response, identify action plan, required PPE select
technical decontamination develop an incident action plan
What three things will be do during terminating incidents?
Ans: Assistant incident debriefing, assistant incident critique, provide
reports and documentation of incident.
Acid
Ans: Forms hydrogen ions in water, pH less than seven, will turn litmus
paper red, because the pressure was in a container to rise particularly if
they become contaminated.
Base
Ans: Hydroxide ions in water, pH greater than seven, will turn litmus
paper blue, because the pressure within a container to rise, particularly
if they become contaminated
Corrosivity
Ans: The concentration of acid, irreversible chemical change in
molecules.
PH
Ans: The numerical measure of a substances relative acidity or
alkalinity.
Strength

Ans: Used to describe the concentration of a solution.
Concentration
Ans: The percentage of an acid or base dissolved in water.
Matter
Ans: Anything that has a mass and occupies space i.e. gas, liquid, solid.
Elements
Ans: Pure substance atoms, cannot be broken down into two or more
pure substances
Compounds
Ans: Contain more than one element. Combined elements.
Mixture
Ans: Substance made up of two or more compounds physically mixed
together
Physical state
Ans: The physical state or form of the material at normal ambient
temperature
Three types of gases
Ans: Compressed, liquefied, cryogenic -130°F
Melting point and freezing point
Ans: The temperature at which a solid changes its phase to a liquid

Ans: Process of going from the gaseous to the liquid state.
Sublimation
Ans: Solid to a vapor phase without passing through a liquid phase
Organic
Ans: Contains carbon, organic materials are derived from materials that
are living or once were living.
Inorganic
Ans: Lack carbon chains
Ionic compound
Ans: The bond between a metal and nonmetal, transfer of electrons.
Covalent compound
Ans: Share electrons.
Boiling point
Ans: The temperature at which a liquid changes phase to a vapor or gas
Expansion ratio
Ans: The amount of gas produced by the evaportion of one volume of
liquid at a given temperature
Flammable range
Ans: Between you UEL and LEL, below the LEL the make sure to lean to
burn above the UEL make sure to Rich to burn
Fire point
Ans: Minimum temperature at which a liquid gives off sufficient vapors
that will ignite and sustain combustion
