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.
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 above mentioned risks, we advise that machine
operators will follow the instructions in the manual at all times.
5.15 PROPANE CYLINDERS
The Propane cylinders are constructed of either aluminum or steel. We recommend aluminum
because it is lighter and guards against rusting. The cylinder used on propane powered trowels
is classified as a 4E240 cylinder. Its rated capacity is 20 lbs. and this designation refers to the
model of the cylinder. Actual propane capacity achieved during filling can be less than, equal to,
or slightly more than 20 lbs. Use only UL, CTC/DOT listed cylinders.
The propane cylinder used on the machine is a motor fuel cylinder as listed by the Department
of Transportation. Unlike the common 20-lb propane outdoor grill cylinders (which are not legal
for use on propane floor machines), the motor fuel cylinder has a number of safety systems
designed into it to ensure your safety at all times.
