Event description

Employees become ill after inhaling carbon monoxide

Investigation abstract

At 9:00 a.m. on September 21, 1989, Employees #1 through #7 entered a work area at the Hyatt Hotel's Alpine Jack Restaurant to remove asbestos. An electric powe r washer was not working so a gasoline-powered machine was brought in as a repla cement. The contained work area had 4,000 cfm negative air ventilation, which wa s not capable of removing carbon monoxide from the machine's exhaust fast enough to prevent carbon monoxide from building up to dangerous levels (estimated in e xcess of 200 ppm). By 11:00 a.m. the employees began to feel sick and by 12:30 p .m. they left the area, suffering from various symptoms. All seven employees wer e hospitalized and one required the use of a hyperbaric chamber.
