2000 ENMET Corporation Appendix A The Characteristics and Effects of Carbon Monoxide Carbon monoxide is a colorless odorless toxic gas generated by incomplete combustion of a hydrocarbon fuel in air. It may be present where internal combustion engines, furnaces, boilers, and other combustion devices are present. It is toxic when inhaled because of its great affinity to hemoglobin, the oxygen carriers in the red cells of the blood. - Page 26 ENMET Corporation 2000 Notes:...
