Wildland Fire Fighter Deaths in the United States: A Comparison of Existing Surveillance Systems

Corey Butler, Suzanne Marsh, Joseph W. Domitrovich and Jim Helmkamp

3. Differences in case criteria in wildland fire fighter surveillance systems may lead to confusion and mischaracterization of data due to differences in the number of captured fatalities. True or False?
