2. SAFETY INSTRUCTIONS
RECOMMENDED USE
The LAVINA® 30GEB machine is designed and manufactured
to grind and polish concrete, terrazzo and natural stone
floors. It can be used for renovations as well as for polishing.
The machine is designed for dry or wet use. When using it
dry, use a vacuum of appropriate size. For more information,
please refer to the chapter on handling the vacuum
connection.
PROHIBITED USE
The machine MUST NOT be used:
For applications different from the ones stated in the
General Description chapter.
In environments which:
-
Possess risks of explosion
-
Possess high concentration of powders or oil substances in
the air
-
Possess risks of fire
-
Feature inclement conditions.
-
Possess electromagnetic radiation.
-
In nursing homes, hospitals, day‐care centers, etc
-
In areas where loose tiles or other objects are
preventing proper use of the machine.
-
In rooms without proper ventilation
-

PREPARATION FOR WORK
Make sure that:
The work area is closed so that no person unfamiliar with
operating the machine can enter the area
The tool plate and tools are mounted on the machine
properly
There are no missing parts of the machine
The machine is in upright working position
The protection devices are working properly.
PROTECTION DEVICES
The machine is equipped with several protection
devices including the following:
A protection skirt and a hood for protecting the tool
plates.
These devices protect the operator and/or others persons
from potential injuries. Do not remove them. On contrary,
before using the machine, please ensure that all
protection devices are mounted and function properly
.
The Envirogard Emissions Monitoring System
ARREST FUNCTIONS
Functions of arresting of the machine are following:
-
Switch to stop the engine
-
Button to stop the grinding movement
-
Close the propane tank
SAFE USE
The LAVINA® 30GEB is designed to reduce all risks correlated with
its use. However, it is not possible to fully eliminate the risks of an
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
-
Entanglement Risks due to wearing inappropriate working
clothes
-
Training Risks due to lack of operational training
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.
