The Graph above depicts the relationships of air exchange to time and CO ppm with cubic feet area and percent CO
emissions remaining constant.

Based on the CO production rates shown above the TW A would not be exceeded in a 100 x 750 x 10 foot (empty) space
after 8 hours with 2 air changes per hour. (Assumes no additional CO exposure during 8 hour time period)
Maintenance of Equipment
Warning: The proper maintenance of equipment is vital to safe operation. LPG engines are dependent
on engine tune up, and air filter replacement CO concentration (production) skyrockets when the air to
fuel ratio becomes fuel rich. Follow the recommended Maintenance Schedule for the engine found in the
Engine Operator/Owner Manual as well as the Maintenance And Adjustments schedule found in the
Propane Floor Equipment Operator's Manual that were supplied with the equipment. Additional manuals
may be obtained by contacting;
Onyx Environmental Solutions at 1-800-858-3533 or write to:

CO Safety Equipment Available:
• Three-way type catalytic converter to scrub CO, Hydro Carbons (HC), and Nitrous Oxide (NOx) from
the engine exhaust providing the lowest possible emissions
• High cubic feet per minute (PM) fans (forced air mixing)
• Digital combustion analyzers for tail pipe emissions monitoring
