OPERATION. An operation occurs when an
object is intentionally changed from another
object; or is arranged for another operation,
transportation, inspection, or storage. An
operation also occurs when information is
given or received or when planning or
calculating takes place. An operation symbol
is also used to represent a person doing work.
TRANSPORTATION. A transportation occurs when
an object is moved from one place to another,
except when such movements are a part of the
operation or are caused by the operator at the
work station during an operation or inspection.
INSPECTION. An inspection occurs when an object
is examined for identification or is verified
for quality or quantity in any of its characteristics.
DELAY. A delay occurs to an object when conditions,
except those which intentionally change the physical
or chemical characteristics of the object, do not
permit or require immediate performance of the.
next planned action.
STORAGE. A storage occurs when an object is kept
and protected against unauthorized removal.
COMBINED ACTIVITY. When it is desired to show
activities performed either concurrently or by
the same operator at.the same work station, the
symbols for those activities are combined, as
shown by the circle placed within the square to
represent a combined operation and inspection.

analysis of the raw ingredients, processes
or storage conditions which could result
in a hazardous situation occurring and
also to determine if suppliers of raw ingredients
comply with commercial and/or
regulatory specifications.
The next step is the production of a
detailed flow diagram for the sous vide
process. A flow process diagram is essentially
a diagrammatic scheme of a plant’s
operations from receipt of raw materials
through processing to packaging, storage
and distribution of finished product and
should be constructed by production specialists
with expertise in these areas.
Each step in the process should be written
down systematically and then
recorded diagrammatically using the
flow diagram symbols shown in Fig. 2
(Apple 1977). Even minor steps, such as
delays in the production process, should
be listed, because even though they may
not be considered important, they could
have an additive effect on the safety of
the product at some other stage further
on in the process. An example of a flow
process chart, summarizing the operations
for a sous vide processed meat/
