A new study report from the University of Oregon suggests that public warnings on wildfire smoke air quality often aren’t issued till after smoke has already swept into the area. The report details recommendations on better communications by public institutions about wildfire smoke and health risks — so that local residents have more time to prepare. More than half of wildfire-related tweets by 32 institutional accounts in 2022 were posted at peak levels of smoke when exposure risk was highest.
“On the one side, these institutions are doing a great job of highlighting the risks when the risks are present,” said Catherine Slavik, a postdoctoral researcher at the U of O Center for Science Communication Research. She said she hopes more of these conversations will occur before it’s too late for affected residents to prepare.
KEZI reported that of 1287 analyzed tweets, only one in seven instructed and encouraged preparation such as wearing respirators, staying indoors, or using air purifiers. Only 213 of all the tweets used AQI labels to report on the smoky air and only 64 described risks with numeric data — such as percentage likelihood of a fire spreading or the number of acres burning.
Recommendations for smoke communications include expressing hazard severity, risk, likelihood, and mitigation, including numeric information and AQI levels when describing risks, practicing community engagement, and discussing risks outside of the fire season.
