2.8 Fire Safety
§ Beware of the potential danger of fire or explosion when using propane, and take
normal fire-safety precautions.
Fire: There is possibilities of fire from LPG vapor Leaking or venting from fuel
tanks 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 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) concentrations.
§ Carbon monoxide is an invisible odorless colorless gas created when fossil fules
(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 machine,
do the following:
1. Stop the engine: Push the throttle to the stop position 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 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 tanks including the ones used on propane powered floor care machines.
• Local Agencies
Local law enforcement agencies such as the local Fire Marshall also rely on independent
testing labs such as UL and CGA before giving their approval of the use of some equipment.
These labs thoroughly test equipment and submit their stamp of approval only after rigorous
testing.
While not being required by all law enforcement agencies, the stamp of approval by these
agencies further assures the operator that he or she is working with and around safe
equipment.
NOTE: In order to reduce all consequences of the abovementioned
risks, we advise that machine operators will follow the
instructions in the manual at all times.
