Based on medical examiner reports and state vital records, 1978-84, nonvehicular carbon monoxide (CO) caused 62 unintended deaths, representing 42 percent of all unintended fatal CO poisonings in West Virginia. Sources were almost always heating or cooking appliances associated with incomplete combustion of fuels (methane, butane, or propane) not commonly recognized for their potential to produce CO. Hazards included failure to provide recommended venting, neglected maintenance, or use in small areas without natural ventilation.
