a
be interesting 1s to visualize the extent
.;
of an atmospheric survey ina plent, This”
4s one of tha feed production plants,
Each one of these represents a
separate exposure evaluation.
These are
the individual people; these numbers re=
present the number of people involved in
each one of these and several bars repre=
sent several successive surveys so that the
plant management, when they see this can
tell how they are doing with respect to
time as well as how they are doing with reo
epect to exposure,
—
Would you run the three of thes
through in quick succession, Al, please?
This is the :major production
people in the plant,
The other two are
similar people but this is one plant, as a
matter of fact, one building in a plant come
plex,
Ag you can see here, (indicating),
they are getting down toward people who are
less involved with production, down to the
managerial personnel and you can see the way
the exposures follow as you get to more ad=
ministrative type people as it falla off,
