![]() An exception to this rule might be an emergency rescue situation in which other options are not available–and then only when equipment operators, assisting personnel, and the victim are provided with supplied-air respirators.Use of gasoline-powered tools indoors where CO from the engine can accumulate can be fatal. NOT allow the use of or operate gasoline-powered engines or tools inside buildings or in partially enclosed areas unless gasoline engines can be located outside away from air intakes.Recommendations for preventing CO poisoning are provided below for employers, equipment users, tool rental agencies, and tool manufacturers.Īll Employers and Equipment Users Should: Prior use of equipment without incident has sometimes given users a false sense of safety such users have been poisoned on subsequent occasions. Often there is little time before they experience symptoms that inhibit their ability to seek safety. Because it is colorless, odorless, and nonirritating, CO can overcome exposed persons without warning. They produce high concentrations of CO–a poisonous gas that can cause illness, permanent neurological damage, and death. It is not widely known that small gasoline-powered engines and tools present a serious health hazard. Operating gasoline-powered engines and tools indoors is RISKY BUSINESS. Opening doors and windows or operating fans does NOT guarantee safety. ![]() Workers in areas with closed doors and windows were incapacitated within minutes. These examples show a range of effects caused by CO poisoning in a variety of work settings with exposures that occurred over different time periods and with different types of ventilation. His symptoms were related to CO poisoning. He experienced a severe headache and dizziness and began to act in a paranoid manner. A plumber used a gasoline-powered concrete saw in a basement with open doors and windows and a cooling fan.Five workers were treated for CO poisoning after using two 8 horse-power, gasoline-powered, pressure washers in a poorly ventilated underground parking garage.Doors adjacent to the work area were open while he worked. A municipal employee at an indoor water treatment plant lost consciousness while trying to exit from a 59,000-cubic-foot room where he had been working with an 8-horse-power, gasoline-powered pump.He had worked about 30 minutes before being overcome. A farm owner died of CO poisoning while using an 11-horsepower, gasoline-powered pressure washer to clean his barn.Examples of such poisonings include the following: CO can rapidly accumulate (even in areas that appear to be well ventilated) and build up to dangerous or fatal concentrations within minutes. Many people using gasoline-powered tools such as high-pressure washers, concrete cutting saws (walk-behind/hand-held), power trowels, floor buffers, welders, pumps, compressors, and generators in buildings or semi enclosed spaces have been poisoned by carbon monoxide (CO).
