-What is Damming... - -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 ... - -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... - -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.
-What is Diking... - -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... - -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... - -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
