Description

Carbon monoxide (CO) is a highly toxic, nonirritating gas. One of the products of combustion, it is invisible, odorless, tasteless, and slightly lighter than air. But smoke, another combustion product, is visible. And when smoke is present, it is highly likely that CO and other noxious gases are present. Therefore, the old adage 'where there's smoke, there's fire' might well be reworded to 'where there's smoke, there's carbon monoxide.' Available evidence indicates that CO concentrations high enough to have adverse effects on firefighters are likely to be common in many wildland fire control operations. In fact, technological advances in firefighting equipment may be contributing to increased exposure. Bulldozers with heat shields and protective blankets, fire-resistant clothing and other protective devices, such as face and neck shields-all encourage entry into areas where significant concentrations of CO are most likely to be found. Carbon monoxide is the most common and widely distributed air pollutant-total emissions of CO exceed those of all other pollutants combined. Although there are a number of natural sources of CO, these contribute little to CO pollution. Most of the atmospheric CO is the result of the incomplete combustion of carbonaceous materials, such as coal, oil, vegetation, and their products. Internal combustion engines, generation of power and heat from burning fuel, and some industrial and manufacturing processes produce large amounts of CO. Today, motor vehicles alone account for more than half of the CO emissions in the United States. Wildland fires and the burning of refuse and agricultural wastes are also major sources.
