What is Damming... ( correct answers ) Physical method of
confinement by which barriers are constructed to prevent or reduce the
quantity of liquid flowing into the environment. Consists of constructing a
barrier across a waterway to stop/control the product flow and pick up
liquid or solid contaminants
What is Underflow Damming ... ( correct answers ) Spill control tactic
used to trap floating lighter than water materials behind the dam. Dam is
constructed in a manner that allows uncontaminated water to flow
unobstructed under the dam while keeping the contaminant behind the
dam.
What is Overflow Damming... ( correct answers ) Spill control tactic
used to trap sinking heavier than water materials behind the dam. With
the product trapped, uncontaminated water is allowed to flow
unobstructed over the top of the dam.
GRADED
A+
, What is Diking... ( correct answers ) Physical method of confinement by
which barriers are constructed on ground used to control the movement
of liquids, sludges, solids, or other materials. Prevents the passage of
hazmat from entering an area where it will produce more harm.
What is retention... ( correct answers ) Physical method of
confinement by which a liquid is temporarily contained in an area where
it can be absorbed, neutralized, or picked up for proper disposal
What is dispersion... ( correct answers ) Chemical method of
confinement by which certain chemical and biological agents are used to
disperse or break up the material involved in liquid spills on water
may result in spreading the hazardous material over a large area.
What is absorption... ( correct answers ) Absorption occurs when
one material enters the cell structure of another and is retianed
within. Absorbents retain the properties of the materials they absorb
and must be treated and disposed of as hazardous material
What is adsorption... ( correct answers ) Adsorption is different from
absorption in that the molecules of the hazardous materials physically
adhere to the adsorbent material Adsorbents do not swell like absorbents
Produces heat and can cause spontaneous combustion must be disposed
of properly.
Examples: activated charcoal, silica, aluminum gel, fuller's eath,
POROUS clay and other clays
What is dilution.. ( correct answers ) Dilution involves applying water
to a water soluble material in order to reduce the hazard. It is a useful
way to preform decontamination but it is not a practical practical spill
control method as it typically requires so much water that it creates a
runoff problem
What is dissolution... ( correct answers ) Dissolution is the process of
dissolving a gas in water. This tactic can only be used on water-soluble
gases such as chlorine or anhydrous ammonia.
What is Diversion... ( correct answers ) Physical method of
confinement by which barriers are constructed on ground or placed in a
waterway to intentionally control the movement of a hazmat into an area
where it will pose less harm to the community and the environment
