To prevent further degradation of local air quality, the NWS suggests scaling back pollution-inducing practices. This includes minimizing the use of motorized vehicles, gas-powered lawnmowers, and other machinery that contributes to emissions. Furthermore, a ban on open burning is in effect; residents should avoid burning debris or any other materials during the duration of the alert.
