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.

2.6 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.
RESIDUAL RISKS
During the normal operating and maintenance cycles, the
operator is exposed to few residual risks, which cannot be
eliminated due to the nature of the operations.
Organizational measures" and "2.14 Safety regarding operation of machine" thoroughly
before operation!
2.7 Propane safety
Propane is a flammable gas whose vapors are heavier than air. As in 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 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 machines are:
§ Carbone Monoxide Poisoning: This is the most frequently reported incident
associated with propane powered 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 emission control
technology and improperly set carburetion.
§ Overfill Fuel Tanks: Nearly all fire related incidents reported result from bringing a
tank into a building without first checking for overfill. This action is dangerous,
unwise and unnecessary.
