What is CAS? - correct answerThe 2010 chemical abstract system registry that lists
over 113 million chemicals
What is terrorism? - correct answerThe systematic use of terror to coerce groups of
people or governments.
What is damaged caused to when hazmats are released uncontrolled from their
containers? - correct answerLife, critical systems, property and the environment
What is the second most effective means for reducing the impact of hazmat incidents on
a community? - correct answerPlanning for them.
Emergency planning is required under which federal law? - correct answerSuperfund
amendments and reauthorization act (SARA)
What are the 3 subchapters of the SARA regulations? - correct answerTitle 1-
emergency planning and notification,
Title 2- reporting requirements
Title 3- general provisions
What is a gas? - correct answerAny material that has a boiling point of less than 68
degrees F
What is a liquid? - correct answerAny material that has a boiling point greater than 68
degrees F
What is a solid? - correct answerAny natural that has a melting point above ambient
temperature
What is boiling point? - correct answerThe boiling point of a liquid is the temperature at
which it changes into a gas or vapor at its max rate.
What are materials with low boiling points classified as? - correct answerVolatile. Which
means they give off large amounts of vapor.
What is vapor pressure? - correct answerThe pressure the vapor of a liquid exerts on its
container when the vapor and liquid are in equilibrium
What kind of boiling points will high vapor pressure have and what kind will low vapor
pressure have? - correct answerHigh vapor pressure = low boiling points
Low vapor pressure = high boiling points
, What measurements are vapor pressure usually expressed in? - correct
answerMillimeters of mercury (mmHg) or pounds per square inch (psi)
What is specific gravity? - correct answerthe ratio of the density of a substance to the
density of water. Water = 1
What is vapor density? - correct answerIts the density of a gas in relations to air. Air
What is solubility? - correct answerA materials ability to dissolve into water or another
specific solvent.
What is miscibility? - correct answerability to be mixed or blended with another
substance
What is volatility? - correct answerThe tendency of a chemical to vaporize or give off
fumes
What is toxicity? - correct answerThe ability of a substance or hazardous material to
cause injury to biological tissue.
What is a poison? - correct answerA substance that is toxic at extremely low levels
What is an asphyxiant? - correct answerA substance that interferes with the
oxygenation of tissue
Describe irritants - correct answerA substance that causes a localized inflammatory
reaction on contact
Describe sensitizers/allergens - correct answerA substance that causes an allergic
reaction
What is a convulsant? - correct answerA substance that causes convulsions or
involuntary muscle contractions
What are carcinogens? - correct answera substance capable of causing cancer in living
tissue.
What are mutagens? - correct answerSubstance that cause changes in the DNA
structure of living organisms, causing mutations
Describe teratogens - correct answerA substance that can cause developmental
abnormalities in fetuses
What are pathogenic materials? - correct answerA substance that can cause illness or
death by bacterial agents, viral agents, toxins
