2.8 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.
2.9 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.
2.10 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.
5.
HAVE THE MACHINE AND CYLINDER INSPECTED
BEFORE USING THEM AGAIN!
2.11 LOCAL AGENCIES AND REGULATIONS
NFPA
Operating a propane powered floor care machine requires
compliance with certain safety regulations. The National Fire
Protection Agency (NFPA) Standard for Storage and Handling of LP
Gas is the appropriate authority for safe propane use. A copy of this
publication is available through the NPFA in Quincy, MA (1‐800‐334‐
3555).
Among its regulations, NFPA #58 requires that all personnel
employed in the handling of propane gas be trained in its proper
handling and operating procedures. It also requires them to carry a
written certification from their employer or training supervisor to
attest to such training. Although this is directed mainly to those who
fill and transport liquid propane gas, Onyx Environmental Solutions
recommends that operators of propane powered floor care
machines in public places be trained and certified as well.
With regard to operation of propane powered floor care equipment,
even though NFPA 58 8‐4.5 says “these machines shall be permitted
to be used in buildings frequented by the public, including the times
when such buildings are occupied by the public,” Onyx
Environmental Solutions suggests usage when occupancy of a given
work area is minimal.
CARB / EPA
The California Air Resource Board (CARB) and Environmental
Protection Agency (EPA) also set limits for propane‐powered
engines used outdoors, but CARB/EPA approval does not signify that
the engine is safe to use indoors.
CGA
The Canadian Gas Association (CGA) has set a limit of 1500 ppm
CO in exhaust flow.
OSHA
For propane powered machines used indoors, the Occupational
Health and Safety Administration (OSHA) has established a limit of
50 ppm CO for 8‐hour time weighted average (TWA) in ambient air
and is considering a limit of 800 ppm CO in exhaust flow.
DOT
The Department of Transportation (DOT) has established regulations
regarding the safety of fuel cylinders including the ones used on
propane powered floor care machines.
