SAFE
USE
The
LAVINA®
25G
‐
S
is
designed
to
eliminate
all
risks
correlated
with
its
use.
However,
it
is
not
possible
to
eliminate
the
risks
of
an
eventual
accident
with
the
machine.
Unskilled
or
uninstructed
operator
may
cause
correlated
residual
risks.
Such
risks
are:
-
Position
Risks
due
to
operator’s
incorrect
working
position
-
Tangling
up
Risks
due
to
wearing
inappropriate

PROPANE
SAFETY
Propane
is
a
flammable
gas
whose
vapors
are
heavier
than
air.
As
is
the
case
with
gasoline,
propane
can
explode
if
the
proper
cautions
are
not
heeded.
Propane
is
odorized
with
an
agent
having
a
distinct
odor
that
is
recognizable
at
very
low
concentrations.
This
helps
in
identifying
leaks,
even
when
they
are
small.
Awareness
and
basic
safety
precautions
are
required
when
working
with
propane.
As
long
as
these
precautions
are
followed,
risk
is
negligible.
Ignorance,
however,
could
pose
needless
risk.
The
two
greatest
hazards
with
propane
powered
floor
care
machines
are:
-
Carbon
Monoxide
Poisoning:
This
is
the
most
frequently
reported
incident
associated
with
propane
powered
floor
care
machines
and
is
caused
by
excessive
exhaust
emissions.
The
symptoms
are
headache,
dizziness
and
nausea.
A
major
cause
involves
engines
with
poor
preventive
maintenance
practices,
usually
those
with
dirty
air
filters
and
machines
operated
in
confined
areas
without
adequate
ventilation.
Another
cause
may
be
substandard,
inexpensive
machines
with
no
emissions
control
technology
and
improperly
set
carburetion.
-
Overfilled
Fuel
Cylinders
:
Nearly all fire relatedincidents
reported result from bringing a cylinder into
a
building
without
first
checking
for
overfill.
This
action
is
dangerous,
unwise,
and
unnecessary.
FIRE
SAFETY
Be
aware
of
the
potential
dangers
of
fire
or
explosion
when
using
propane,
and
take
normal
fire
‐
safety
precautions.
Fire:
There
is
a
possibility
of
fire
from
LPG
vapor
leaking
or
venting
from
fuel
cylinders
or
carburetion
equipment.
Explosion:
LPG
vapor
concentrated
or
confined
to
a
small,
restricted
space
may
explode
or
ignite.
Propane
may
experience
a
BLEVE
,
a
boiling
liquid
expanding
vapor
explosion.
EMISSIONS
All
propane
powered
floor
care
machines
produce
emissions.
Most
are
harmless,
but
some
are
dangerous
and
can
be
fatal.
Carbon
monoxide
(CO)
poses
the
greatest
risk,
since
CO
can
be
lethal
within
as
little
as
30
minutes
exposure
at
3,000
parts
per
million
(ppm)
concentration.
Carbon
monoxide
is
an
invisible,
odorless,
colorless
gas
created
when
fossil
fuels
(such
as
gasoline,
wood,
coal,
propane,
oil
and
methane)
burn
incompletely.
HAZARD
COMMUNICATION
A
Material
Safety
Data
Sheet
for
propane
shall
be
posted
in
all
buildings
where
propane
will
be
used.
Because
propane
is
odorized,
it
is
easily
detected
at
levels
of
just
a
few
parts
per
million,
which
is
much
less
than
the
exposure
limit
of
1000
parts
per
million.
If
you
smell
propane
while
operating
a
propane
floor
care
machine,
do
the
following:
Stop
the
engine
:
1.
Pull
the
throttle
to
the
stop
position
(if
present)
or
turn
the
key
switch
to
the
off
position.
2.
Shut
off
the
service
valve
on
the
propane
cylinder.
3.
Move
the
floor
machine
to
a
well
‐
ventilated
area.
4.
Remove
the
cylinder
from
the
machine
and
take
it
outside
the
building.
5.
If
the
cylinder
is
leaking,
contact
a
DOT
approved
repair
shop
to
determine
the
cause
of
the
leak
and
have
the
shop,
not
you,
repair
it.
If
a
fire
occurs
while
the
machine
is
being
operated,
do
the
following:
1.
Stop
the
engine:
pull
the
throttle
to
the
stop
position
(if
present)
or
turn
the
key
switch
to
the
off
position.
2.
Shut
off
the
service
valve
on
the
propane
cylinder
if
possible.
Be
careful
not
to
be
burned.
3.
Move
the
machine
outside
if
possible.
If
not
possible,
move
it
to
a
well
‐
ventilated
area
away
from
flammable
materials.
4.
Do
not
attempt
to
extinguish
the
flame
from
a
gas
leak.
If
you
do,
the
gas
will
build
up
in
the
area
and
could
re
‐
ignite.
Starve
the
fire
by
shutting
off
the
supply
of
gas.
