A
Good
morning,
Commissioners
Jim
Richardson
division
chief
for
fire
rescue,
EMS
Department
of
Public
Safety.
If
we
I'd
like
to
dispense
with
reading
the
memo
and
go
ahead
and
turn
it.
B
A
A
Yeah
Mikey
Clark
assistant
chief
with
the
Huntingtown
volunteer
fire
department
and
rescue
squad
he's
also
chairman
of
the
Calvert
County
Chiefs
Council
Brent
Langford,
chief
of
the
Saint
Leonard
volunteer
fire
department,
rescue
squad
and
Mike
Farrell
firefighter
EMT
with
Huntington
volunteer
fire
department
rescue
first
I'd
like
to
thank
you
for
showing
an
interest
in
these
lithium
ion
batteries.
By
the
end
of
this
work
session,
we
hope
you
have
a
better
standing
of
the
batteries
as
well
as
the
dangers
that
come
along
with
them.
D
Morning,
good
morning,
nice
to
be
here
today
with
you
guys
my
name
again,
my
name
is
Mike
Farrell
with
the
Huntington
volunteer
fire
department
and
I'm
just
going
to
walk
you
through
a
pretty
comprehensive
understanding
of
lithium-ion
batters
where
they
came
from,
where
they're
at
in
our
community
and
what
kind
of
risks
that
it
poses.
It
is
a
fairly
Consolidated
report.
Certainly,
if
you
want
additional
time
and
more
information
on
us,
we
can
certainly
provide
that,
for
you.
D
In
here,
oh
so,
some
of
the
things
we'll
be
going
over
this
morning
is
just
to
explain
some
of
the
general
understandings
of
the
rechargeable
lithium-ion
battery
we'll
determine
some
of
the
sequence
events
where
this
actually
becomes
an
emergency.
We'll
present
some
operational
procedures.
Chief
Lankford
will
be
taking
you
through
how
the
fire
department
will
respond
in
there
to
these
Lithium-ion
batteries
and
some
of
the
challenges
that
provides
or
presents
itself
to
the
fire
department
and
then
certainly
illustrate
going
forward.
What
do
we
need
to
manage
this
risk
in
Calvert
County?
D
So
the
first
thing
I
want
to
take
you
through
is
why
use
Lithium-ion
batteries,
so
everything
I
have
here
is
basically
compared
against
your
sulfuric
acid
battery.
Your
car
battery,
that
has
been
a
energy
storage
system.
Up
to
this
point,
just
a
little
bit
of
History,
the
lithium-ion
battery
was
actually
created
back
in
1985
and
it
was
actually
in
production
in
1991
by
the
Sony
company,
through
some
technological
advancements
and
things
like
that,
it
does
last
longer.
D
It
will
provide
an
energy
source
for
a
longer
period
of
time
compared
to
that
sulfur
or
sulfuric
acid
battery.
It
has
a
higher
power
density,
which
means
it
provides
more
energy
for
whatever
it's
trying
to
operate
and
then
certainly
has
a
longer
life
expectancy,
and
it
has
a
lighter
package.
So
it
adds
it
actually
subtracts
a
lot
of
that
added
weight
to
that
device
that
you're
trying
to
push
pull
or
power
to.
D
Foreign,
so
when
we
get
into
the
actual
emergency,
it's
very
important
to
understand
how
this
battery
works,
so
I'm
going
to
kind
of
break
this
down
very
simplistic
for
you.
It's
just
a
general
lithium
ion
rechargeable
cell
and
you
have
an
anode
and
a
cathode,
and
that's
how
that
energy
is
actually
passing.
Those
lithium-ion
particles
through
that
electrolyte,
which
is
in
the
middle
of
that
picture,
that
electrolyte,
is
what's
causing
the
problem
in
the
middle
of
that
electrolyte.
D
You
have
a
separator
and
that
separator's
job
is
to
keep
that
cathode
and
ion
separated,
but
it
also
stabilizes
that
battery
and
if
that
separator
becomes
compromised
or
what
we
call
Battery
insult,
which
I
will
give
you
some
demonstrations
of
exactly
what
battery
insult
is
it's
causing
these
problems
when
that
separator
starts
to
fail?
That's
when
the
battery
starts
to
become
unstable
and
that's
when
we
can
actually
have
an
emergency.
Also,
the
understanding
of
that
electrolyte
is
actually
a
liquid
material
and
that
liquid
material
is
hydro
is
a
hydrocarbon
base,
which
means
it
is
flammable.
D
When
we
look
at
this
and
I'll
show
you
how
these
individual
cells
are
packed
inside
there.
These
modules
have
several
of
these
cells
inside
them,
and
here's
just
some
of
the
examples
of
the
different
technology
that
that
is
being
used
in
the
commercial
industry,
I'll
just
kind
of
start
up
at
the
top
right
corner
there.
D
That
Prismatic
you've
probably
seen
this
in
your
rechargeable,
your
your
cameras
and
things
like
that,
if
you
ever
have
to
actually
pop
that
out
and
put
it
in
a
charger,
it's
a
fairly
small
hardened
shape
and
what
they're
doing
is
they're
actually
wrapping
that
lithium-ion
technology
inside
there,
nice
and
tight,
then
at
the
bottom
right
corner.
You
have
the
pouch,
that's
very
common
in
a
lot
of
your
electronics
very
thin.
These
are
actually
used
a
great
deal
in
cell
phones.
Your
laptops
things
like
that.
D
But
as
technology
is
advancing,
this
lithium-ion
technology
is
yielding,
where
they're
actually
using
these
pouch
Concept.
In
a
lot
of
your
much
larger
apparatus,
Vehicles
things
like
that
they're
seeing
pouch
technology,
then
of
course,
your
button
cell
itself,
the
Button
cell,
very
common,
a
lot
of
your
medical
equipment.
Things
like
that
pacemakers
you'd
find
these
in
key
fobs
recharge.
Your
electronic
key
starts
like
we
have
for
keyless
Vehicles
things
like
that
and
then
finally,
I.
D
D
The
module
itself
which
is
interesting
is,
is
because
there's
such
a
need
and
demand
of
this-
that's
where
the
the
the
the
value
is
and
that's
where
the
dollar
amount
is
so
there's
a
lot
of
companies
that
are
building
these,
maybe
not
as
safe
a
lot
of
aftermarket
products
and
things
like
that.
So
there's
an
actual
Electronic
Module
on
that
battery
module
that
prevents
it
from
being
overcharged
under
charged
things
like
that.
So
you
can
get
a
lot
of
these
aftermarkets
that
are
out
there
for
consumption.
D
You
can
actually
get
a
minute
where
they'll
actually
to
save
money,
remove
that
modular
off
so
now
it
is
unsafe,
but
it's
being
sold
as
a
commodity
for
people
to
use
and
and
people
think
they're
saving
money.
You
know,
because
there
is
a
lot,
a
lot
of
cost
Associated
to
this.
This
kind
of
Technology
actually
had
a
lot
of
it
wasn't
as
attractive
because
back
in
the
early
90s,
even
the
early
2000s.
D
C
D
D
So
let
me
go
back
one:
oh
all
right
so,
first
day
on
the
job.
So
here
we
have
here
just
some
examples
of
where
is
this
at
in
our
community?
I
mean
I,
get
it
here
in
Calvert
County.
We
I
just
broke
them
down
into
Transportation
energy
storage
and
an
expanding
Market
of
a
consumer
electronic
devices
and
things.
D
So
if
we
look
in
the
top
left
corner
golf
carts,
buses
for
public
transportation,
your
wheelchairs,
even
your
e-bikes,
that
electronic
bike
actually
will
assist
in
moving
that
vehicle
and
things
and
we're
seeing
this
more
in
herb
environments
where
you're
seeing
the
bike
sharing
program
and
things
like
that.
D
Certainly
you
could
see
that
kind
of
and
people
can
buy
those
right
off
the
market
themselves
and
have
that
in
their
homes,
the
energy
storage,
so
energy
storage
is
becoming
a
very,
very
big
market
and
the
concept
is
is
instead
of
using
a
combustible
engine
like
a
diesel
generator
things
like
that,
you
actually
are
using
the
power
grid
to
to
charge
these
batteries
up
and
then,
when
there
is
a
power
or
failure
of
domestic
power.
These
things
click
right
on
with
no
or
any
change
in
power
to
that
area.
D
D
One
of
the
attractive
ways
to
move
with
this
Builder
is
that
they
will
have
an
energy
storage
system
for
that
community
and
they're
very
similar
to
about
a
sea
container
and
they'll,
be
individual
modular
packs
of
these
Lithium-ion
batteries
that
just
sit
in
there
and
they'll
usually
plant
like
trees
and
stuff.
So
it's
camouflaged,
it's
not
an
eyesore,
so
if
any
power
is
lost
to
that
Community,
these
things
automatically
kick
right
on
and
you
may
not
even
realize
that
that's
what's
inside,
that
container
is
this
energy
storage
system.
D
Currently
there
there
is
no
federal
legislation
to
my
knowledge
that
I
was
able
to
find
where
there
is
a
required
extinguishing
system
integrated
into
there.
So
you
have
to
be
very
aware
through
pre-planning
and
things
like
that,
that
they're
in
your
community
and
then
they
are
and
then
how
we
would
extinguish
them.
There
was
a
very
serious
incident.
I
can
take
you
through
in
great
detail
at
another
time
if
you're
interested
in
Sunrise
Arizona,
where
one
actually
detonated
and
several
firefighters
were
severely
from
that
emergency
and
then
the
expanding
Market.
D
This
is
where
we're
seeing
a
lot
of
this,
where
you're,
seeing
your
wearable
your
eye,
watches
your
Apple
watches
things
like
that.
Your
fitbit's
smartphones,
the
lithium-ion
rechargeable
batteries,
probably
in
everyone's
pocket,
these
consumer
Commodities
I,
would
be
very
safe
to
say,
there's,
probably
thousands
just
in
the
buildings
right
now
in
these
Calvert
County
buildings,
from
cell
phones
to
laptops
to
anything
you
can
imagine,
toys
are
becoming
more
and
more
prevalent,
I'm
sure
everyone
saw
the
hoverboard
and
things
like
that.
D
The
e-bikes
they're
moving
up
into
more
like
a
moped,
if
you
will
kind
of
size
or
scooter
size
where
we're
seeing
more
and
more
of
these
the
cordless
phone
and
then,
of
course,
the
power
tool.
I'm
sure
all
of
us
have
lithium-ion
rechargeable,
drills
and
saws
and
weed
eaters,
and
all
that
stuff
plugged
in
probably
right
now
waiting
to
be
used
when
we
need
them
and
what
I
want
to
show
you
is
is
to
understand
how
these
things
are
actually
going
to
cause
US
problems
and
that's
where
we
we
move
into
thermal
Runaway.
D
So
this
is
what
we
call
Battery
insult
and
Battery
insult
is
basically
something
has
caused
some
kind
of
physical
stress
to
that
battery.
Again,
like
I
stated
earlier,
that
separator
becomes
compromised
and
that
electrolyte
starts
to
heat
up
and
that
cell
that
you
see
in
the
top
left
corner,
one
cell
starts
to
actually
heat
up
and
actually
that
flammable
hydrocarbon
electrolyte
will
catch
fire
and
then
that
cell
will
catch
fire.
Well,
those
cells
are
packed
in
there
very,
very
tight.
D
So
once
one
goes
off,
the
next
one
will
go
off
and
so
on
and
so
forth
to
where
you
have
a
modular
and
then
actually
the
entire
pack,
and
that's
where
you're,
seeing
that
propagation,
where
it's
continuing
to
burn
out
of
control.
So
once
one
heats
up
and
that
temperature
starts
to
rise
and
starts
to
release
that
flammable
and
toxic
gas,
it's
going
to
ignite
and
continue
so
on
and
so
forth.
D
C
D
A
scientific
study
that
was
conducted-
and
they
did
this
several
times
to
get
an
average
and
you're
looking
about
zero
to
five
seconds.
One
cell
will
actually
go
into
thermal
one
away
once
it's
actually
has
that
separator
compromised
at
5
to
20
seconds
now.
Six
cells
are
in
thermal
runaway
and
then
at
40
seconds.
D
18
cells
are
now
in
thermal
runaway,
so
you
can
see
how
exponentially
this
small
incident
starts
to
expand
itself
and
as
these
things
begin
thermal
one
way
when
you
see
that
propagation
up
there,
the
temperatures
that
are
coming
off
this
is
a
thousand
degrees,
so
sheet
metal
will
actually
fail
at
6
or
600
Degrees,
and
still
it
starts
to
elongate
at
a
thousand
degrees.
So
this
is
very,
very
high
temperature
coming
off
here.
So
if
this
is
around
any
kind
of
combustible
materials,
you
can
now
see
how
you
have
rapid
flame
spread.
D
So
what
we
I
have
here
is
is
hopefully
this
will
come
up.
I
have
a
video
here,
and
this
is
with
a
thermal
imager.
So,
that's
why
you
see
those
different
colors
and,
of
course,
the
brighter
the
color,
the
hotter.
It
is,
and
they're
actually
going
to
take
this
battery
pack
and
put
it
into
thermal
runaway
and
you're
going
to
see
how
this
thing
is
going
to
start
to
yielding
heat.
And
it's
going
to
start.
D
Throwing
heated,
shrapnel
and
stuff
like
that,
and
that's
the
thing
to
be
in
mind
is
that
when
this
actually
starts
to
go
into
thermal
runaway,
it
starts
to
fragment
and
it
will
actually
Propel
heated
cells
away
from
the
source
again.
So
if
it
throws
it
across
this
room
anywhere,
it
comes
in
contact.
That
thousand
degrees
is
going
to
start.
D
D
So
Chief
Lankford
is
going
to
kind
of
take
you
through
step
by
step
from
the
fire
department's
side,
but
I
just
really
want
to
focus
again
like
we
talked
about
the
temperatures
itself,
but
also
some
of
the
toxic
gases
that
are
yielded
from
this
hydrogen:
highly
flammable
gas
coming
off
this
carbon
dioxide,
carbon
monoxide,
even
some
of
your
acidic
gases,
and
things
like
that,
you
could
actually
find
out
there.
Sir.
C
Do
they
have
stats
on
how
often
these
are
failing,
I
I
remember:
there
was
talk
on
planes
with
this
stuff
and
I.
Remember
we
had
a
thing
at
work
where
one
of
our
computers
wasn't
working.
Of
course,
young
guys
know
about
all
the
stuff
he's
like
you
got
to
unplug
it
like.
What
do
you
mean?
He
goes
it's
heating
up
like?
What
do
you
mean
it's
heating
up?
We
actually
had
this
battery
backup
that
came
with
it
so
that
it
went
down
and
kicked
on
us.
D
So
statistically,
no
there
is
nothing
where
the
the
reality
is
is
that
there
are
trillions
of
these
being
used
throughout
the
world.
It's
just
become
a
more
prevalent
and
because
of
that
supply
and
demand
you're,
finding
producers
that
are
being
able
to
make
these
battery
packs
for
a
lower
cost
and
start
cutting
corners
and
I.
Think
that's
where
you're
finding
a
lot
of
that
causing
issues.
These
batters
are
being
discharged
and
recharged
every
day.
The
problem
is,
it
may
be.
D
E
D
So
if
I
have
my
e-scooter
and
I
ride
it
around
and
I
bring
it
in
typically
I,
don't
want
to
drag
it
all
the
way
through
the
house,
because
the
tires
are
dirty
things
like
that,
so
I
plug
it
right
in
by
the
front
door,
and
then
this
battery
pack
goes
into
thermal
runaway
because
it's
been
battery
insult
whatever
and
now
when
it
starts
to
do
that
process.
We
just
saw
it's
right
by
my
means
of
egress
to
get
out
of
the
structure
and
now
I've
actually
compromised
the
entire
structure.
G
So,
first
and
foremost,
the
fire
department
will
always
operate
in
a
fundamental
system,
regardless
of
the
emergency
unit
to
arrive
on
the
seat
of
the
emergency
and
immediately
conduct
Life,
Safety
or
life-saving
operations
to
control
confine
eliminate
and
mitigate
the
threat
to
life
of
property
in
the
environment,
so
prior
to
an
actual
emergency
being
dispatched.
There's
a
proactive
approach
to
a
lot
of
these
things,
first
and
foremost,
as
Mike
had
mentioned
pre-planning.
G
So
the
first
thing
that
we
normally
do
as
Chiefs
in
the
county
is
create
standard
operating
guidelines
to
standardize
a
response
throughout
the
throughout
the
county.
That
way,
if
there
is
a
response,
whether
in
Huntington,
St,
Leonard
anywhere
in
between
or
otherwise
that
we
understand
what
we're
not
only
responding
to.
But
what
resources
are
coming.
G
We
also
plan
on
suggest
that
we
start
working
with
the
portions
of
the
Calvert
County
government
to
identify
the
target
hazards
that
we
currently
have
here
in
the
county
and
what
could
be
potentially
coming
in
the
future,
so
I'd
be
working
with,
like
Waste
Management,
to
see
where
they
store
their
the
items
down
at
the
landfill
or
at
the
other
waste
facilities.
G
The
talk
with
Planning
and
Zoning
to
see,
if
there's
anything
that
they're
notified
of
someone's,
installing
maybe
battery
packs
into
the
house
or
a
charging
port
for
like
a
Tesla
or
another
vehicle,
not
sure
the
answer
to
that
right
now,
but
as
the
vehicles
get
bigger,
they
might
require
more.
You
know
battery
draw
start
going
to
tractors
or
you
know
other
vehicles.
G
The
next
proactive
approach
would
be
with
Education
and
Training.
So
what
we
want
to
focus
on
is
a
standardized
repeatable
approach
to
training,
to
ensure
that
all
the
responders
receive
the
same
type
of
training.
This
has
already
started
in
Calvert
County
Huntingtown
fire
department
hosted
a
eight-hour
lithium-ion
battery
emergency
training,
March
25th
that
all
departments
were
invited
to,
and
then
we
also
have
vendor
specific
training.
G
So
those
would
be
such
as
test
lifting
a
one
vendor
out
there
for
cars
or,
if
there's
other
vendors
that
come
out,
you
would
get
that
vendor-specific
training
at
St
Leonard.
We
hosted
a
vehicle
vendor
specific
training
on
February
25th
and
then
the
other
big
thing,
as
Mike
alluded
to
would
be
education
of
the
public
at
our
open
houses.
G
Education
at
community
events
to
talk
about
as
these
devices
become
more
prevalent,
where
you
should
charge
them,
how
you
should
charge
them
and
safety
if
there
is
an
emergency
prior
to
the
fire
department
getting
there
and
then
the
last
thing
in
the
proactive
approach
would
be
equipment
procurement
that
would
be
where
each
fire
department
or
the
fire
department
together
conducted
market
research
on
relevant
equipment
that
may
be
implemented
into
the
fire
and
rescue
operations.
There's
a
couple
devices
out
there
right
now.
G
Now,
obviously
the
market
is
getting
bigger
every
year,
so
and
as
there's
more
money
in
the
market,
you
have
people
who
develop
other
fire
suppression
systems,
and
this
will
change
from
year
to
year,
as
the
market
becomes
a
bigger
cost,
then
we'll
get
into
the
response
aspect
of
it.
So,
as
I
alluded
to
before,
our
primary
goal
is
life
safety.
We
arrive
on
the
scene
if
there's
any
life
safety,
that's
the
for
our
first
goal
and
second,
it's
going
to
be
containing
the
situation
and
that
will
be
dependent
on
what's
involved.
We've.
G
You
guys
spoke
about
on
an
airplane
where
they
had.
They
actually
have
looks
like
what
you
get
your
pizzas
warmed
up
in
a
container
where
you
would
throw
an
iPad
or
a
phone
in
there
and
that'd,
be
something
very
simple
that
you
could
mitigate
that
situation
almost
immediately.
G
We
start
getting
to
the
bigger
vehicles,
it
becomes
difficult
or
bigger
batteries,
it
becomes
very
difficult,
and
that
leads
us
to
how
we're
going
to
extinguish
those
bigger
things,
because
it's
a
battery
fire,
there's
no
risk
for
electrocution,
so
water
is
the
best
way
to
extinguish
these
fires.
The
problem
is,
is
how
much
water
it's
going
to
take
to
put
the
fire
out
and
get
to
where
the
battery
is
because
they
are
contained,
as
Mike
said,
get
in
there
and
make
sure
that
the
buyer,
the
fire
is
completely
out.
G
There's
been
situations
where
fires
have
reignited
hours
and
days
after
we've
or
the
fire
departments
have
determined
that
they've
been
put
out
as
well
as
it.
Sometimes
it
takes
thousands
of
gallons
of
water.
It
could
be
a
prolonged
situation
where,
if
you
have
a
Tesla
fire
on
a
highway
that
you
know
there
could
be
roads
shut
down
for
three
or
four
hours
and
then
after
the
situation
is
mitigated.
We
need
to
worry
about
overhaul
and
disposal
of
what
was
on
fire.
G
So
if
you
have
a
vehicle,
for
example,
it's
on
fire
there's
a
potential
again
that
it
could
catch
fire
hours
or
days
later.
So
we
need
to
work
with
the
sheriff's
department,
as
well
as
the
tow
companies
to
make
sure
that
regardless
of
the
vehicle
was
even
on
fire.
If
it
was
involved
in
the
accident,
there's
potential
for
the
puncture
to
the
battery
that
they
need
to
store
these
vehicles
and
batteries
away
from
anything
other
that
could
could
catch
fire
would
be
other
vehicles
or
buildings.
G
C
G
So
at
this
point
in
time
it
would
be
dispatched
as
a
garage
fire
and
hopefully
working
with
the
control
center.
We
can
get
them
to
start
asking
those
questions
if
they
have
any
potential
battery
involvement
with
it,
whether
it
just
be
a
car
or
you
know
anything
else,
people
tend
to
put
their
Tools
in
their
garage
and
the
other
batteries
that
Mike
had
alluded
to
earlier.
One
of
the
things
with
putting
the
fire
out
in
this
situation
is,
like
I,
said
getting
to
it.
G
G
The
biggest
thing
would
be
to
start
putting
the
fire
out
now.
One
of
the
nice
things
is
is
that
it's
difficult
to
get
to
the
battery,
but
putting
out
the
things
that
the
battery
is
caught
on.
Fire
is
relatively
easy
to
do.
The
prolonged
period
is,
we
do
have
the
ability
to
use
winches
other
other
things
to
remove
a
car
or
even
get
a
tow
company
or
something
that
could
come
down
and
possibly
do
it
for
us,
as
we
are
using
the
water
to
make
sure
that
the
vehicle
stays
cool.
G
The
biggest
thing
is
to
put
out
the
fire
itself
and
again
it
might
not
just
be
the
car
on
fire,
it
could
be
other
elements
and
then,
once
the
car,
the
the
fire
is
actually
out
getting
to
the
battery
itself
and
getting
into
those
cells.
That's
what's
going
to
take
the
most
amount
of
time,
so,
once
the
fire
is
out,
we
probably
would
be
able
to
knock
all
visible
fire
down
and
then
now
we
need
to
worry
about
just
making
sure
that
the
vehicle
itself
stays
cool.
G
C
G
So
there
is
a
a
device
called
the
best
device
that
is
manufactured
by
rosenbauer.
That
will
allow
you
to
go
in
it's
kind
of
like
a
Ghostbusters
when
they
slide
it
out
and
do
the
tract
of
goods.
But
you
slide
this.
Under
the
car
there
punctures
the
battery
and
then
floods
the
battery
cell
with
water
that.
G
We
have
St
Leonard's
put
in
for
a
special
project
to
get
one
of
those
after
July
1
when
the
new
budget
is
approved,
so
we
potentially
will
have
one
that
could
be
used
throughout
the
entire
County
after
July
1
of
this
year.
G
It's
not
100
effective,
because
if
you
can't
get
to
the
exact
cell,
that's
on
fire
or
if
the
cells
don't
overlap,
you
might,
it
might
take
several
punctures,
but
that
will
decrease
the
amount
of
water
that's
needed,
but
on
a
first
initial
alarm,
we're
coming
what
is
being
dispatched?
Is
you
have
upwards
of
12,
000
gallons
of
water
that
will
be
coming
to
the
scene,
which.
G
It's
hard
to
say
what
will
be
enough,
because
every
fire
and
every
emergency
is
different
depends
on
the
size
house.
What's
on
fire,
how
big
the
vehicle
is,
how
long
it's
been
burning
for
ETC
and
like
I
said.
So,
if
it's,
if
the
homeowner
calls
right
away
and
it's
right
down
the
street
from
one
of
the
fire
stations
and
we
get
there
right
away,
we
might
be
able
to
mitigate
that
situation
very
quickly
and
put
out
what
is
visibly
on
fire.
But
then
again
it's
getting
the
hidden
fire
within
the
within
the
battery
itself.
G
If
it's
a
prolonged
response,
because
it's
you
know
so
the
neighbor
notices
the
garage
on
fire,
then
a
lot
of
that
water
is
going
to
be
to
put
out
what
was
on
fire
when
we
arrived,
not
just
cooling
down
and
seeking
the
hidden
Fire
Within
the
battery
itself.
So
each
each
situation
it's
hard
to
tell
how
much
water
we'll
need,
but
we
have
a
good
start
with
getting
there.
E
G
Ma'am
there's
the
potential
for
those
gases.
Now
I
will
say
that
every
fire
you
go
to
which
involves
smoker
and
what
we
call
an
idealh
environment.
There
is
potential
to
be
exposed
to
dangerous
gases,
but
our
breathing
apparatus.
It's
a
positive
pressure
system.
We
do
fit
testing
every
year
to
make
sure
our
mask
of
the
firefighters
fit
correctly
will
help
prevent
us
being
exposed
to
those
gases,
provided
that
we're
wearing
the
app
the
breathing
apparatus
the
entire
time
and
in
situations
like
these,
because
a
lot
of
those
gases
after
the
smoke
is
gone.
C
G
It's
potential,
like
anything
that
would
involve
a
Hazmat
situation,
would
depend
on
the
weather.
The
wind
I'll.
Give
you
another
example:
there's
you
know
electronic
vehicle
charger.
Electronic
Vehicles
can
be
in
a
parking
garage
in
North
Beach,
that's
an
enclosed
environment
I
mean
you're.
Potentially,
you
know
not
only
just
a
garage
which
might
be
smaller,
but
you
have
the
ability
to
have
these
effect
more
than
one
vehicle
or
multiple
people
within
an
enclosed
environment
citizens,
not
just
the
fire
department.
G
For
the
charging
stations-
yes,
sir,
so
basically
after
we
were
sort
of
charged
with
this
project,
it
really
opened
our
eyes
to
kind
of
the
resources
we
want
to
get
into
to
start
talking
to
the
people
to
see.
If
they
can
give
us,
you
know
Planning
and
Zoning,
or
you
know,
mining
speak
to
this
Commissioners.
A
I
actually
reached
out
to
inspection
and
permits
and
had
a
discussion
with
Joe
and
he's
working
on
something.
That's
going
to
be
very
helpful
to
the
fire
departments
in
Calvert
County
there's
been
a
significant
increase
in
permits
and
electrical
for
these
high
voltage
plugs
for
these
EB
vehicles
and
garages
he's
going
to
get
that
information
so
that
can
be
sent
out
to
the
department,
so
them
responding
to
a
fire
at
that
house.
A
They
would
then
have
something
in
front
of
them
showing
that
they
have
a
plug
that
could
possibly
have
an
EV
vehicle
in
that
garage.
So
again,
with
you
guys
sparking
this
we've
reached
out
and
that's
in
the
works
right
now,
so
that'll
be
most
helpful
to
the
Departments.
H
A
C
I
John
Norris
County
attorney,
commissioner.
There
was
legislation
proposed
in
Annapolis
this
year
that
would
have
superseded
any
zoning
regulation
for
a
community
generating
size
facility.
They've
got
Public
Service
Commission
approval
that
bill
through
the
efforts
of
the
Maryland
Association
of
counties
and
its
County
Partners
was
modified
so
that
there
is
some
recognition
of
the
importance
of
following
a
comprehensive
plan.
But
the
trend
is
towards
pushing
solar
into
the
rural
communities,
to
feed
back
into
the
urban
areas
and
to
do
rooftop
solar
in
urban
areas.
I
B
The
only
thing
we
could
do
is
restrict
future
development
surrounding
a
facility
that
might
prevent
significant
danger
concerns,
but
we
can't
prohibit
the
site
from
locating
itself
near
those
types
of
areas.
Correct.
B
There
is
not
one
thing
we
can
do
and
that
triggered
at
least
I
have
a
little
bit
of
fire
experience
and
for
you,
knowledge
of
the
scene
before
you
arrive,
is
extremely
important
and
I
was
concerned
about
you
rolling
up
on
a
residence
with
an
electric
car
in
the
garage,
and
maybe
the
fire
hasn't
extended
into
the
garage.
Yet.
But
you,
knowing
that
that
car
is,
there,
is
important
and
there's
more
and
more
solar
rooftop
being
installed
and
some
of
those
have
battery
backups.
And
you
need
to
know
that.
B
Recently
there
was
a
house
fire
in
Virginia
was
ignited
by
an
electric
bike
that
gentleman
had
no
idea
when
he
parked
his
bike
in
his
living
room.
It's
going
to
burn
his
house
down,
so
we
need
to
help
you
with
your
public
awareness
of
and
we're
not
trying
to
stop
people
from
buying
electric
cars
or
electric
bikes.
B
We
just
want
to
make
sure
the
Public's
aware
that
when
you
place
these
devices,
because
you
know
a
laptop
laptop
can
set
a
fire,
but
as
these
batteries
get
bigger
and
bigger,
the
danger
becomes
exponential
and
that
we
want
to
make
sure
our
citizens
are
aware
of
they
shouldn't
things.
They
shouldn't
do
like
I
said
and
whatever
we
can
do
to
help
you
so
that
you're,
aware
of
what's
out
there.
C
Mr
President
I
think,
if
it's
possible,
if
we
could
get
a
work
session,
maybe
County
Administrator
could
find
us
some
expert
from
the
state
to
speak
to
these
solar
Farms,
because
you
know
obviously
the
rural
areas
we
always
take.
The
brunt
of
the
decisions
get
made
in
three
jurisdictions
and
the
other
21
are
supposed
to
file
suit,
but
we
get
it
all,
and
if
we
have
no
say
that
at
least
our
citizens
should
have
every
piece
of
information
that
will
you
destroy
your
property
forever?
Will
you
take
a
chance
of
harming
your
neighbors
everyone
else?
B
Our
presentation
at
Mako
they
talked
about
these
solar
Farms.
These
batteries,
as
you
showed,
and
sea
containers
full
of
these
batteries,
and
because
I
do
have
a
little
bit
of
experience.
They
they
compared
it
to
a
nuclear
facility
where
you
can't
put
it
out
and
your
job
is
to
evacuate
everybody
downwind
as
far
as
you
think
you
should,
because
the
toxins
in
that
smoke
and
it
I
had
no
idea
until
I
heard
that
presentation.
So
that's
why
we're
here
today
and
today's
the
first
step.
You
know
your
work's
not
done
today.
J
G
You
talking
about
like
getting
a
container
and
actually
putting
the
vehicle
in
there
yeah.
We
we
we're
doing
our
research.
We
had
talked
about.
You
know,
sort
of
the
best
way
and
that's
something
that
they're
doing
in
Europe
a
lot
right
now
is
just
getting
you
know,
there's
containers
just
emerging
in
there,
and
that
would
be
very
time
intensive
and
resource
tax
in
order
to
have
down
here
in
Calvert
County,
but.
B
You
know
by
the
time
the
old
combustion
in
cars
are
gone.
There's
going
to
be
a
point
in
time
where
every
car
or
vehicle
run
up
down
this
road
is
electric
and
it's
gonna
be
a
necessity
for
us.
Maybe
not.
Every
department
has
one,
but
that
we
have
some
available,
because
if
you
can't
put
them
out
and
if
they're
going
to
trucks,
you
know
if
I've
got
a
truck,
you
think
a
Tesla
is
bad.
What's.
H
B
School
bus,
what's
my
track
a
tractor
trailer
or
how
big
a
battery
is
that
thing
gonna
have
to
have
and
it's
running
up
and
down
the
road
every
day
or
tractors
or
bulldozers
or
whatever.
So
it's
a
minor
problem
now,
but
it's
going
to
be
exponentially
in
the
next
20
years.
G
B
Things
that
are
going
to
change
technology
is
going
to
change
by
the
time
we
get
there.
There
may
be
better
equipment
or
preventive
measures
that
you
all
can
take
use
to
extinguish
these
things.
But
you
know,
based
on
what
we
know
today,
trying
to
think
ahead.
It's
something
that
we
have
to
prepare
for
adapt.
D
You
know
would
be
my
recommendation
as
I
was
doing
research
on
this.
These
energy
storage
systems
that
you're
speaking
of
they
seem
like
they
have
a
very
good
handle
on
that
situation,
they're,
usually
pretty
segregated
from
any
kind
of
occupancy
area.
Some
of
them
have
integrated
extinguished
systems,
they're
sealed
up
airtight.
So
if
we,
you
know
you
would
move
in
on
it
you
you
can
really
slow
it
down.
Just
like
Chief
Lankford
was
saying
our
first
priority
is
life
safety?
There's
nobody
in
there
then
just
slow
down.
D
Now
it's
a
property
incident
where
we
have
to
be
concerned
learned
about
you
know
the
economical
impact
of
that.
The
bigger
concern
is
when
you
see
that
slide
where
I
broke
it
down
into
consumer
robotics.
That's
the
concern,
that's
the
concern,
because
you
can
now
buy
cheaper
lithium-ion
battery
packs
that
have
basically
have
they
don't
have
all
the
safety
incorporated
into
it.
Hence
why
it's
cheaper
and
now
you're
putting
it
into
an
apartment,
building
or
you're,
putting
it
in
a
townhouse
announced
that
it
just
one
townhouse.
C
D
So
in
most
cases
they
would
suggest
that
you
do
that,
but
the
problem
is
Sir.
Is
that
what
it
does?
Is
you
hear
a
pop,
and
that
is
a
safety
relief
where
it's
actually
releasing
that
electrolyte
has
gone
from
a
liquid
to
a
gas.
It's
pressurized
and
you'll
hear
a
pop.
The
next
thing
is,
you
will
see
a
white
smoke,
but
that's
actually
a
toxic
flammable
gas.
The
heat
is
already
there
so
seconds
later,
just
like
when
I
broke
that
timeline
down
to
you.
D
To
throw
it
in
the
window,
not
no.
It's
best
to
get
out
of
the
structure
because
whatever's
happening
the
normal
citizen
in
Calvert
county
is
not
going.
C
D
D
There's
not
much
things
blow
out
of
it.
100
it
will
actually
throw
batteries,
will
actually
so
the
vehicles
not
to
get
because
I
know
time
is
very
precious.
I
want
to
be
on
it,
be
respectful
of
that
with
you
today,
but
they
actually
packed
them
in
a
an
epoxy
material
on
the
vehicle.
So
they
can
take
a
little
bit
more
of
that
insult,
but
when
it
explodes
it
will
actually
discharge
those
like
shrapnel
but
they're,
a
thousand
degrees.
D
So
now
they're
going
under
the
cars
they're
hitting
other
combustibles,
and
now
you
think
you're
dealing
with
one
vehicle,
but
now
you
have
all
these
other
things
that
are
igniting
as
well.
So
again,
my
my
focus
for
for
a
risk
management
standpoint
wouldn't
necessarily
be
the
energy
storage
systems.
I
think
it
would
be
more
the
com,
the
consumer,
based
in
a
multi-uh
occupied
dwelling
on
a
apartment,
building
our
townhouses
that
are
all
from
the
north
to
the
South
and
the
county.
Those
things
can
be
coming
very
difficult.
D
D
Right
and
that's
where
that
module
that
I
spoke
about
was
integrated
in
there
with
the
more
expensive
material
they're
actually
going
to
have
that
on
there
to
disable
that
to
prevent
that
incident
from
occurring
going
into
thermal
runaway.
But
if
I
have
a
cheaper
product,
I'm
not
going
to
put
that
module
on
there
and
you're
not
going
to
know
that.
Because
again
we
all
we're
all.
You
know
mindful
of
our
money,
if
I
think
I
can
get
it
200
cheaper
from.
D
G
I
was
I
I,
don't
necessarily
have
an
answer
to
that.
We
can
ask
Barbara
Warner
who's
the
grant
writer
for
Public
Safety
if
she's
seen
anything
but
I
I
do
imagine
as
it
becomes
more
popular.
There
will
be
definitely
higher
price
extinguishing
items
or
ways
to
mitigate
the
situation
and
that
the
grants
would.
If
you
can
justify
the
need
for
them,
then
they
will
be
there.
Okay,.
H
K
Mike
Clark
I'm,
the
assistant
chief
at
Huntington
fire
department,
which
engine
are
you
talking.
H
About
for
the
electrical
vehicle?
Yes,
it.
K
Left
on
charge
over,
so
it's
just
a
overcharged
vehicle
and
it
did
Sparky
fire
at
the
Milwaukee
Avenue
storage
facility.
H
B
Well,
I
think
that,
unfortunately,
if
you
thought
your
work
was
done,
it's
not
and
I,
don't
think
you
thought,
but
what
we
would
ask
is
that
you
continue
to
work
with
County
staff
and
whoever
you
need
to
bring
into
that
discussion
and,
as
you
identify
issues
things
that
we
can
help
you
with
that
we're
here
to
do
that,
you
know
Communications
signage,
whatever
you
all
identify,
we
want
to
make
sure
staff's
on
board
to
help
you
and
we'll
work
you
through
that
and
I
just
want
to
remind
the
public,
that's
out
here,
watching
Chief
Lanford
and
Mr
Farrell
and
Mr
parks
in
his
private
life.
B
When
he's
not
working
for
us
are
all
volunteers
and
the
presentation
that
you
just
watched
was
put
on
by
our
volunteers
and
it's
why
we
have
such
an
outstanding
volunteer
fire
service
in
Calvert
County,
because
I
would
challenge
our
staff.
You
know
that
they
would
put
on
you
know
a
presentation
at
this
level.
So
I
want
to
thank
you,
gentlemen,
for
what
you
do
for
our
citizens
every
day
and
Chief
Clark,
who
didn't
have
a
lot
to
say:
you're
sitting
back
there
but
yeah.
B
F
Commissioners
as
they're
packing
up
Marshall,
Sky,
administrator,
Mary,
Beth
cook,
director
of
Planning
and
Zoning,
is
in
the
room,
and
one
of
the
reasons
that
she's
here
is
that,
when
they
started
putting
solar
panels
on
roofs
and
firefighters
had
to
fight
had
to
cut
their
way
into
the
building.
That
prompted
us
to
look
at
what
in
inspections
and
that
we
would
use,
but
also
here
just
to
learn
what
they
had
to
say
about
what
we
can
help
them
with
going
forward.
Right.
