Why should gasoline generators not be run in enclosed parking garages?

Gasoline generators produce combustion gases, one of the most dangerous being carbon monoxide (CO). This colorless, odorless gas can accumulate quickly in enclosed spaces, such as parking garages, where there is limited ventilation. Even at low levels, carbon monoxide can cause symptoms such as headaches, dizziness, and confusion. At higher concentrations, it can lead to unconsciousness or even death. The risk is significantly heightened in enclosed environments, where the gas cannot dissipate effectively. Therefore, operating a gasoline generator in such settings poses a serious health hazard due to the potential for carbon monoxide poisoning.
