摘要

Because of the risk of carbon-monoxide (630080) (CO) poisoning, this Alertprovides a warning not to use equipment and tools which are powered by gasoline engines inside buildings or spaces which are partially enclosed unless the engine itself can be placed outdoors and away from air intakes. Seven instances of CO poisoning of persons using small gasoline powered engines and tools are briefly described. The early warning signs of CO poisoning (headache, dizziness, and nausea) are nonspecific and may be mistaken to for symptoms of other illnesses. CO poisoning causes confusion and weakness which can inhibit a person's ability to escape the hazardous environment. Health effects of CO poisoning, current standards and recommeneded guidelines, data summarizing CO poisonings, and information supporting the rapid buildup of CO are described and discussed. Recommendations for employers, equipment users, tool rental agencies, and tool manufacturers are presented.
