This document provides interim guidance to reduce the risk of introducing and transmitting SARS-CoV-2 (the virus responsible for causing COVID-19) in cleaner air shelters and cleaner air spaces. Cleaner air shelters and cleaner air spaces are public spaces where people can seek relief from wildfire smoke. This interim guidance is intended for use by federal, state, local, and tribal jurisdictions in the United States. It should be used in conjunction with existing cleaner air shelter information, procedures, guidance, and resources.
