OSHAIndoor Air Quality Standard # 1910.1000
The Occupational Safety and Health Administration (OSHA) has taken the lead on hazardous emissions
in the workplace by creating and enforcing a CO (carbon monoxide) emissions standard that all
workplaces must follow.
The official wording of the stand is as follows:
'The CO (carbon monoxide) concentration of an enclosed workplace (i.e. a building with no fewer
than 3 walls) must be no greater than 35 ppm in the ambient air (i.e. the air around the working
machines that workers breathe) over an eight hour work shift."
This emission standard is not a tailpipe standard although many OSHA inspectors fail to test properly
as they do take their samples at the tailpipes of machines.
The reason that OSHA has targeted CO is that this particular emission when exposed to humans will
restrict our blood cells ability to absorb oxygen, as a result causing lethargy, lightheadedness and
eventual suffocation. The development of cancer has also been linked to long term exposure to CO.

California Environmental Protection Agency EXECUTIVEORDERU-R-02S-0183Air Resources Board Kubota Corporation New Off-Road
Compression-Ignition Engines
Pursuant to the authority vested in the Air Resources Board by Sections 43013,43018,43101,43102,43104 and 43105of the Health and Safety Code; and
Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 ofthe Health and Safety Code andExecutive Order G-02-003;
IT ISORDEREDAND RESOLVED:That the following compressionOignition engines and emission control systems producedby the manufacturer are certified as described below for use in off-road equipment. Production engines shall be in allmaterial respects the same as those for which certification is granted.
Special Features & Emission Control System Typical Equipment Application
The engine models and codes are attached.The following are the exhaust certification standards (STD) and certification levels (CERTS)for hydrocarbon (HC), oxidesof nitrogen (NOx), or non-methane hydrocarbon plus oxides of nitrogen (NMHC+NOx), carbon monoxide (CO), andparticulate matter (PM) in grams per kilowatt-hour (g/kW-hr), and the opacity-of-smoke certification standards andcertification levels in percent (%) during acceleration (Accel), luggin (Lug), and the peak value from either mode (Peak)for this engine family (Title 13, California Code of Regulations, (13 CCR)Section 2423):
Rated Power Emission Exhaust (g/k-W-hr) Opacity (%)Class Standard HC NOx NMHC+NOx CO PM Accel Lug I Peak
BE IT FURTHERRESOLVED:That for the listed engine models, the manufacturer has submitted the information andmaterials to demonstrate certification compliance with 13 CCRSection 2424 (emission control labels), and 13 CCRSection 2425 and 2426 (emission control system warranty).
Engines certified under this Executive Order Must conform to all applicable California emission regulations.
This Executive Order is only granted to the engine family and model-year listed above. Engines in this family that areproduced for any other model-year are not covered by this Executive Order.
NOTE: These readings are WITHOUT the catalytic converter.
Capital Demolition & Construction Equipment DOES have catalytic converters installed.Please refer to our 'Clean Air Scrubber' link on our Safety & Equipment Page for further
information regarding the catalytic converters installed on our equipment.
