Containment
Definition:
The actions taken to
keep a material in
its container. (e.g.,
stop a release of
the material or
reduce the amount
being released.)

Absorption

The process by which
one substance, such
as a liquid, combines
with another
substance, such as a
solid, by becoming
part of that substance.

Diking/Damming: The use of a barrier to
confine the movement of a material.
Diversion: The controlled movement of the
liquid from one course of flow or area to a
another locale.
Retention: The temporary confinement of
a material in an area (e.g. pond,
excavation, etc.). (Often used in
conjunction with diversion.)

Remote valve shutoffs

Valves that can be
used to shut off the
flow of a chemical; the
term remote is used to
denote the valves that
are away from the spill
or release.

Practical Exercise
You are dispatched for the investigation. Upon arrival, you
find a tanker truck that is leaking an acid. It is leaking at
a moderate rate. You must determine and perform the
best method of product control.
