Sase PDG 6000 - Emissions Awareness; Carbon Monoxide (CO) Hazards

o Always install propane cylinders onto machinery in a well-ventilated area with no source of ignition within 10 ft
(3 m).
o Use only UL, CTC/ DOT listed cylinders, like the EnviroGard Safe-Fill cylinder.
o Never leave the machine running unattended.
o Operate in a well-ventilated area.
o If you smell gas:
o Do not operate appliances, telephones, or cell phones. Do not turn lights or flashlights on or off. Flames
or sparks from these sources can trigger a fire or explosion.
o Evacuate the area immediately.
o Shut off the gas if it is safe to do so.
o Report the leak from a safe location.
o Do not return to the building until you are told it is safe to do so.
Emissions Awareness
o Carbon Monoxide (CO) poisoning can be caused by excessive exhaust emissions. The symptoms include
headache, dizziness and nausea. Causes include:
o Engines with poor preventative maintenance practices, usually those with dirty air filters.
o Machines operated in confined areas without adequate ventilation.
o Substandard machines with no emissions control technology and improperly set carburetion.
o CO is an invisible, odorless, colorless gas.
o CO can be lethal within as little as 30 minutes exposure at 3,000 part per million (ppm).
o The Canadian Gas Association (CGA) has set a limit of 1,500 ppm CO in exhaust flow.
o The Occupational Safety and Health Administration (OSHA) has established a limit of 35 ppm CO for an 8-hour
time weighted average in ambient air and is considering a limit of 800 ppm CO in exhaust flow.
