Alert Smoke-Ready Toolbox for Wildfires

Smoke from wildfires can adversely affect air quality and put people at health risk from smoke exposure. Public health officials and others can use the resources in the Smoke-Ready Toolbox to help educate people about the risks of smoke exposure and actions they can take to protect their health.
