The Federal Emergency Management Agency and the U.S. Fire Administration have released their annual report about the number of firefighter fatalities for 2012. This year their numbers for those killed on wildland fires are the same as those provided by the National Wildfire Coordination Group, which is not always the case.
According to the report:
In 2012, 15 firefighters were killed during activities involving brush, grass or wildland firefighting. This total includes part-time and seasonal wildland firefighters, full-time wildland firefighters, and municipal or volunteer firefighters whose deaths are related to a wildland fire.
