The EnviroGard Emissions Monitoring System.
the Engines are equipped with the EnviroGard EmissionsMonitoring System.
This system provides a unique, state-of-the-art, fail-safe means for ensuring
emissions safety to operators and other personnel in environments where
propane equipment is used.
EnviroGard employs a sensor in the exhaust path between the engine and the
catalytic muffler to detect the oxygen content of the exhaust before it is
passed through the catalyst. The oxygen sensor does not react to nor does it
measure the CO content of the exhaust. It responds only to oxygen content.
The oxygen sensor produces an electrochemical signal that is sent to the
EnviroGard Control Module. If the magnitude of this signal is not within the
preset control limits, the Control Module will activate the shut down sequence
and the engine will stop running.
The control limits are preset in the control module at the Onyx factory. The
air-fuel ratio is then adjusted prior to shipment and the CO content at the
exhaust, measured by a digital CO detector.
The Control Module is set to ignore the readings from the oxygen sensor
during the first three minutes the engine is running. This period allows:
1. The sensor to reach a stable operating temperature.
2. The catalyst in the muffler to reach the temperature necessary to reduce
the levels of CO, nitrogen oxides (NOx) and hydrocarbons (HC) in the
exhaust.
The most common event in which the Control Module shuts down an engine
is when the air filter becomes dirty enough to restrict the air intake flow, which
changes the air-fuel ratio such that the oxygen sensor signal is outside the
control limits. Once the air filter is properly cleaned, operation of the machine
can be resumed.

PERSONAL PROTECTIVE EQUIPMENT (PPE)

Always wear safety shoes when working with the machine.
All personnel in the immediate work area must wear safety glasses with side
shields.
Always wear safety gloves when changing the tools.
Always wear clothes suitable for the work environment.
Always wear Carbon Monoxide Indicator badges as an extra precaution.
The plastic indicator contains a colored indicator button that darkens in the
presence of Carbon Monoxide. The relative darkness of the indicator button
indicates the level of CO in the ambient atmosphere. Most indicator badges
have a useful life of 30 days, depending on the concentration of
contaminants, humidity, and temperature.
Testing
There are a great number of instruments offered on the market to test for toxic
gases. Only those designed to read carbon monoxide resulting from
combustion engines are considered acceptable for testing exhaust emissions
from propane powered floor machines.
Some instruments are used to read "ambient air" and may be damaged if
used to take readings in the muffler or tail pipe.
Selecting the proper instrument is an important part of meeting the testing
requirements.
Generally speaking, units capable of reading in ppm, (parts per million), at
ranges from 0 to 1000 are adequate for checking ambient air (air in the
breathing zone of the operator). Instruments capable of testing carbon
monoxide in the exhaust should be able to read from 0 to at least 2000 ppm
and should be certified by the manufacturer for that purpose.
