E, Operational plans for services such asfengineering, fire,
Police, rescue and wardens must provide flexibillty and
versatility.
The radiation situation may requir@
that personnel
of such services for a time perform duties otherfthan those for
which they &re primarily trained, or may deny tha
performance of
those duties.
F. The term "shelter" as distinguished frdm
"cover"
is used
to mean construction which is sufficient to affo
substantial
protection to persons within it, from blast, the
1 effects, and
initial and residual radiation.
"Cover" refers
structures which
will offer protection from radioactive fallout,
yond the range of
other effects.
G. Since fallout progresses over & considefPable period of
time and its path can usually be predicted within] broad limits,
in
contrast with the almost instantaneous blast and
fhermal effects,
eivil defense countermeasures can be adjusted to
fhe developing
situation and thereby greatly increase survival clances.
H. Any evacuation plan to avoid the blast
must take into account the availability of shelteg
g@nd thermal effects
or cover, the
speed of movement which can be achieved and the pdssibility of
identifying areas of relative safety with reasonatle accuracy.
Beyond the probable range of blast and thermal effects, the
emphasis should be placed on advising people to seek the most
effective cover available (see para V. B 2) and td
remain there
until the radiation outside has fallen to safe le
is.
I.
People must be informed concerning the
ture of the
danger and the measures which they can take, inclufling personal
Gecontamination.
Standing tnstructions must be prgpared and
4ssned by civil defense officials establishing thel procedures
which are
to be carried
out,
