from the text "Ruby [1] helped identify minor text mistakes or areas for clarification that occurred in Collins et al. [2]. The text mistakes in the article do not affect the study results and in each case help to strengthen clarity of the study methods and validity of the results. For this, Dr. Ruby is thanked for his evaluation. In the final paragraph of Collins et al. [2], the reference to Butler et al. [3] is incorrect, as indicated by Ruby [1]. The correct reference is the report of wildland firefighter (WLFF) fatalities from 2007–2016 by the National Wildland Coordinating Group (NWCG) [4], which supports statements in Collins et al. [2] that cardiac arrest was the leading cause of WLFF fatalities between 2007 and 2016 (24%). Over this period, vehicle accidents constituted 20% and aircraft constituted 18% of fatalities. We agree that the latter two categories were greater between 1990 and 2006, and when the two categories are combined for the 2007–2016 period."
