WARNING!
Read and understand The Operators Manual completely before using this machine
This document explains how CO produced can be managed to reduce the risk of carbon monoxide poisoning.
All distributors, owners, and operators should be aware of the potential effects of CO and the methods used to prevent over exposure.
We are dedicated to our customers, their safety, and providing information, services, and products that meet those needs.
WARNING!
The Products sold with this Manual contain or may contain chemicals that are known to certain governments (such as the State of California, as
identifi ed in its Proposition 65 Regulatory Warning Law) to cause cancer, birth defects or other reproductive harm. In certain locations (including
the State of California) purchasers of these Products that place them in service at an employment job site or a publicly accessible space are
required by regulation to make certain notices, warnings or disclosures regarding the chemicals that are or may be contained in the Products at
or about such work sites. It is the purchaser's responsibility to know the content of, and to comply with, any laws and regulations relating to the
use of these Products in such environments. The Manufacturer disclaims any responsibility to advise purchasers of any specifi c requirements that
may be applicable to the use of the Products in such environments.
DOCUMENT OVERVIEW
The information provided in the following overview has been condensed to provide the reader with a summary of the material presented.
Potential Effects of CO Exposure
• Work place occupational exposure guidelines for CO exposure limits vary substantially from region to region. For example, the (OSHA)
Permissible Exposure Limit (PEL) for CO is 50 ppm, as an 8-hour time weighted average (TWA); however, some countries have adopted the
ACGIH Threshold Limit Value (TLV) of 25 ppm CO. Some states (such as Minnesota) enforce a TWA PEL of 35 ppm CO, with an allowable
ceiling of no more than 200 ppm..
• Defi nition of CO effects - The toxic effects of carbon monoxide in the blood are the result of tissue hypoxia (lack of oxygen). The severity
depends on the state of activity of the individual and his tissue oxygen needs.
Methods to Reduce The Risks of CO Poisoning
• Air Exchange and CO Diffusion - CO does not mix with air on its own. Air currents can "stir" the CO and dilute the concentration values by
mixing it with the available air. When using equipment over a large area in a short time "stirring" occurs as you walk.
• Application Considerations (Burnishing versus Stripping) - When activity is concentrated to a smaller area as in a stripping application, air
"stirring" must be forced by the use of fans to reduce the risk of high concentrations of CO.
• Air Quality Monitoring – Deployment of a monitor/detector for suffi cient continuous fresh air supply is essential for the safe operation of any
equipment that has the potential to produce CO. NOTE: Dead Stop CO Detector provided in Literature Pack. Replacement part number
98758A.
• Room Size and Time Estimations - The concentration and volume of CO production, the size of the area and the amount of air exchange are
factors involved with determining safe time limits for operation in a specifi c room size.
• Maintenance of Equipment - LPG engines are dependent on engine tune up, and air fi lter replacement. Toxic CO exhaust emissions severely
increase when LPG engines run poorly or are in a poor state of maintenance. Follow the recommended Maintenance Schedule for the
engine.
• Safety Equipment Available. - Envirogard automated fuel to air ratio monitoring and regulation providing an optimum combustion, catalytic
converter muffl er to scrub CO, Hydrocarbons (HC), and Oxides of Nitrogen (NOx) from the engine exhaust providing the lowest possible
emissions, high cubic feet per minute (CFM) fans (forced fresh air mixing), and digital combustion analyzers for tail pipe emissions
monitoring.
