Good
morning
everyone!
It
is
my
pleasure
to
give
a
presentation
here.
As
a
student
whose
major
is
safety
engineering,I’d
like
to
introduce
a
safety
evaluation
method
today,the
LEC
evaluation.
As
the
PPT
shows,my
presentation
is
mainly
divided
into
three
parts.
Firstly,let
me
introduce
LEC
briefly.
Maybe
some
of
you
have
learned
about
LEC
in
college,it
is
used
to
assess
the
degree
of
danger
when
people
work
in
potentially
dangerous
environment.
It
is
a
half-quantitative
safety
evaluation
method
which
classifies
one
certain
system
and
determine
if
the
system
is
safe
enough.
Then,what
does
each
letter
mean?
D
means
danger,it
shows
how
dangerous
the
system
is.
L
means
likelihood,it
shows
the
possibility
of
the
accident.
E
means
the
extent
of
exposure,it
shows
that
how
often
do
workers
work
in
dangerous
environment.
C
means
consequence,it
shows
the
severity
of
accidents.
Here,it
is
a
chart,each
part
is
divided
into
several
levels.
Take
the
likelihood
as
an
example,it
has
seven
levels,the
points
range
from
0.1
to
10
as
the
possibility
rising.
And
if
the
score
of
D
is
over
320,it
means
this
system
is
extremely
dangerous
and
cannot
continue
operating.
Through
LEC
evaluation,we
can
make
sure
if
we
need
to
rectify
and
reform
the
workplace,so
that
we
can
take
some
measures
for
safety
to
avoid
accidents.
It
is
easy
to
use
and
it
is
feasible
for
the
situation
which
is
lack
of
specific
evaluation
models
or
data.
The
LEC
method
is
widely
used
in
various
fields,such
as
aircraft
industry,railway
industry,metallurgic
industry,coal-mining
industry
and
so
on.
The
usage
of
LEC
doesn’t
have
many
differences.
Firstly,we
should
select
the
evaluation
unit,then
identify
the
main
danger
in
the
unit.
Next,we
need
to
evaluate
the
danger
by
using
that
chart
and
get
a
conclusion
.
