We carry tools with us fighting wildland fire. Pulaskis, chain saws, shelters, gloves, sunglasses, sunscreen. A tool you may not consider, and one often overlooked, is the tool of listening.

The National Fallen Firefighter Foundation (NFFF) took the tool of listening across the country in six cities over the course of four months – from October 2017 to February 2018 – to hear and learn how to reduce wildland fire line-of-duty deaths and injuries.
