2025 WOR: Frog Fire Entrapment – July 30, 2015

Letter to LeadershipDay 1  |  Day 2  |  Day 3  |  Day 4  |  Day 5  |  Day 6  |  Day 7  

 

Incident Summary:

On the evening of July 30, 2015, 38-year-old Engine Captain, David “Dave” Ruhl, from the Black Hills National Forest, was entrapped and killed while scouting on foot during initial attack (IA) of the Frog Fire on the Modoc National Forest in Northeastern California. The lightning-caused fire was detected at 1732, and an hour after ignition began to rapidly spread through pine, juniper, brush, and grass fuels under the influence of outflow winds. It was around that time that the first of the IA resources arrived on scene and assumed control of the emerging incident.
Dave Ruhl, in his role as an acting Battalion Chief, arrived on scene roughly 20 minutes later and assumed command as Incident Commander Type 4 (ICT4), with the original IC as his trainee. Dave began scouting the fire perimeter, alone and on foot. Around 1915, Dave was heard over the radio communicating with a helicopter, requesting information about values at risk in front of the fire. Dave’s voice was calm and professional.

The fire continued to grow and was now burning through the wet lines laid down by the responding engines. Over the radio, Dave and his trainee agreed to meet face-to-face to transition to a higher complexity Incident Commander Type 3 (ICT3) organization. Dave never arrived at this meeting, and subsequent attempts to contact him via phone and radio were unsuccessful. At 1930, a 90-degree wind shift triggered the disengagement of suppression resources on the fire. With Dave still unaccounted for, the disengagement from suppression freed up overhead to search for him. 

Sadly, Dave was not found until the following day at 0917. He had apparently been cut off and overrun by fire at about 1936 the previous evening.

Map of Event:

Discussion: 

  • How often do you scout alone? Do you prefer to scout alone?
  • Are there tools to help build situational awareness on initial or extended attack fires to help make scouting more efficient and safer?
  • How can you protect yourself when you are scouting alone?

ETC/RMC Safety Bulletin: 25-001 New Guidance on Laundering Wildland Fire Clothing to Reduce Contamination

Date: Aug 8, 2025
Questions? Please contact:
Equipment Technology Committee
 Risk Management Committee

The Equipment Technology Committee (ETC) and the Risk Management Committee (RMC) have issued Safety Bulletin 25-001: Laundering to Decontaminate Wildland Fire Clothing. Recent research revealed that wildland fire flame-resistant pants and shirts can be contaminated with chemicals from combustion byproducts, including carcinogens, and that common laundering practices can effectively remove these harmful contaminants from wildland firefighter clothing more effectively than previously understood. It is recommended to decontaminate wildland fire clothing as frequently as possible. 

Frequently Asked Questions about this new information and how to implement recommendations can be found on the NWCG Alerts page. Read the complete ETC/RMC Safety Bulletin: 25-001 to learn more.
