A report has been released by the Wildland Fire Lessons Learned Center about a dozer rollover that occurred July 2, 2016 at the Trailhead Fire on the Eldorado National Forest in California. You can read the entire report, but here’s a brief summary.

After getting unstuck from being high centered on a large stump, a dozer operator found himself off the ridge where he was building an indirect fireline, and was on a steep slope. Again he got stuck and was not able to backup, this time due to the slope which in places exceeded an 80 percent incline. At various times he was advised by two Resource Advisors, the Structure Group Supervisor, and the owner of the dozer to stay put. In the meantime another dozer with a winch was en route to assist.

Ignoring the advice, the operator continued down the slope and got into a heated argument with the owner, who then left the area. Determined to get the dozer back up to the ridge top, the operator began building a road and creating pads where he could work to push over trees that were in his way, including a 30-DBH cedar which missed by 50 feet the two Resources Advisors who had to run to get out of the way.

The incident-within-an-incident finally came to an end, at least temporarily, when the dozer rolled over onto its side. The operator escaped with only a scratch, after which the dozer continued to roll over onto its top in the creek bottom.

The report did not include information about how the dozer was eventually extracted, or what repercussions, if any, befell the operator and the contractor.

Report released on escaped prescribed fire in northern Minnesota

The fire burned 1,008 acres on the Superior National Forest.

A report has been released for a prescribed fire that escaped on May 19, 2016 and burned an unexpected 1,008 acres 10 miles west of Ely, Minnesota. The U.S. Forest Service had intended to burn 78 acres, but extremely dry conditions and winds pushed a spot fire beyond the capabilities of the Hotshot crew and the engine initially assigned to the project. The fire danger index for the Energy Release Component at the time was setting 20-year maximums.

The perimeter of the planned prescribed fire is outlined in black, in the gray shaded area. The escaped area is in red.

You can read the entire report here, but below are highlights:

  • Some of the firefighting resources listed as contingency forces in the burn plan were national resources not committed to the prescribed fire and were assigned to other fires when needed on the escape.
  • According to a spot weather forecast the conditions that morning were at the hot end of the prescription and in the afternoon may go out of prescription. There was a discussion about possibly having to pause ignition for a period of time in the afternoon.
  • The test fire began at 11:40 a.m. Soon thereafter the primary ignition began.
  • Within 40 minutes of starting the test fire spot fires began to occur near the fireline, but they were suppressed. At 12:50 p.m. a larger spot fire, 1/4 to 1/2 acre, was discovered 100 yards north of the main burn by firefighters patrolling in a canoe. The firing boss ordered the igniters to slow down.
  • When the larger spot fire occurred, firefighters installed a hose lay from a river to the site but were not able to start a pump to supply the water. A replacement pump that had been working in another area that day was brought in but it also refused to run.
  • At 12:53 p.m. a water-scooping Beaver air tanker that could carry up to 130 gallons of water was requested by the Zone Fire Management Officer (ZFMO) who was at the site, and 11 minutes later he asked for a Type 3 helicopter.
  • At 1:41 p.m. personnel on the fire declined offers or suggestions for “heavy aircraft” and also a Type 1 helicopter that had become available.
  • Between 1:59 p.m. and 2:26 p.m. personnel on the fire requested the Type 1 helicopter, air attack, two 20-person crews, a CL-415 scooping air tanker, and two large air tankers.
  • At 2:07 p.m. the Burn Boss declared the escaped fire to be a wildfire and began shutting down the original prescribed fire.
  • At approximately 1700 a Type 2 Incident Management Team was ordered for the escaped wildfire, which was then several hundred acres in size.
  • At 10:09 p.m. all personnel on the prescribed and escaped fires were released and returned to Ely.

Report released for burn injuries on Tokewanna Fire

On July 29 a member of the Great Basin Smokejumpers was injured while scouting fireline on the Tokewanna Fire near Mountain View in southwest Wyoming. The firefighter sustained burn injuries to the hands, calves, knees, elbows, cheeks, nose and ears. He was transported by air ambulance to the Salt Lake Burn Center where he was admitted.

The fire started at about 1500 on July 28. The overhead structure worked through the night and began transitioning to replacement personnel after smokejumpers arrived at approximately 1252 on July 29. The person that was later burned became the new Division Supervisor (DIVS) on Division W at 1300. Official transition to the new Incident Commander occurred at 1505.

Below is an excerpt from the Factual Report that was completed September 15, 2016:

“Between 15:30 and 15:45 the DIVS was scouting fireline and reached the highest point of where the fire had progressed on the ridge. At this location a flare up occurred downhill from the DIVS on the other side of a large stringer of lodgepole pine which had been heavily treated with retardant (Reference Materials photos 2-5). The DIVS stated, “I heard something I didn’t like and determined I needed to leave.” He retreated to his predetermined safety zone, which was the black and opted to continue downhill rapidly. While retreating he experienced an extreme pulse of radiant heat coming from the right accompanied by smoke and blowing ash. Because of the pulse of radiant heat, he used his helmet to shield the right side of his face. In recounting this he expressed “I wish I had my gloves on, but prior to the event I was away from the fire edge using a GPS and taking notes in my notepad.” The radiant heat caused burns to the DIVS’s hands, calves, knees, elbows, cheeks, nose and ears.”

Also from the report:

Summary

Three key findings were brought out during this investigation:

  • Timely recognition and reporting of burn injuries is critical
  • The absence of PPE can contribute to the severity of injuries
  • Firefighters were unable to contact the air ambulance utilizing pre-established radio frequencies

Lessons Learned from the Interviewees:

When asked if there were any lessons learned or best practices the interviewees would take away from the incident the following was captured:

  • Recognize your own limitations and don’t expect to have all of the answers or information on a rapidly emerging fire.
  • Time of day and incident complexity were not optimal for transferring command, but in this case it was a better option than continuing to utilize fatigued resources.
  • Sometimes you just need to safely engage to ensure you are not transferring risk to someone else later.
  • Make the time to tie-in with your overhead to assure face-to-face interactions occur during transition.
  • Participation with district resources in pre-season scenario based training alleviated tension while coordinating a real life medical incident at the dispatch center.
  • Frequency sharing with local EMS will help facilitate efficient medevac procedures.
  • Continue to encourage EMS certifications among line firefighters and/or identify ways to improve access to Advanced Life Support on emerging incidents.”

Report released on entrapment of six firefighters on the Cedar Fire in Arizona

A report has been released on the entrapment of six firefighters that occurred on the Cedar Fire south of Show Low, Arizona June 28, 2016.

The firefighters were part of the Navajo Interagency Hotshot Crew (NIHC) that remained along with two Type 6 engines and possibly one other crew after the Type 1 Incident Management Team was released the previous day. The assignment of half the crew, nine firefighters, was to “monitor” a part of the southwest side of the fire that had six miles of uncontained fire edge. The other half was working on the southeast side.

Three of the nine personnel on the southwest side served as lookouts while the remaining six were monitoring and checking the fire edge. When a very large fire whirl developed near the six, they realized their escape route was cut off, and took refuge in a previously burned area. The ground fuels had burned, but the canopy was still intact. As the fire approached they deployed their fire shelters, remaining in them for about 30 minutes.

After the fire whirl subsided, the squad members were able to hike out to staged vehicles. They were transported in three ambulances, medically evaluated, and transported to Summit Hospital in Show Low, Arizona where they were evaluated. Two firefighters were treated for smoke inhalation and all were released by 10 p.m. that evening.

The report says the personnel deployed and entered the shelters just as they had practiced several times in training, and the devices worked as designed. There were no difficulties, as reported at other entrapments, with the PVC bags becoming soft and difficult to open.

Thankfully there were no serious injuries and the training the firefighters had received paid off.

But there are a number of interesting facts about what occurred before the entrapment

Resources on the fire

On June 27, the day before the entrapment, the Type 1 Incident Management Team issued their final update on the 45,977-acre fire just before they were released later that day. Below is a portion of the document.

The report claims the Type 1 Team recommended that the number of personnel assigned be reduced on Tuesday June 28 to about 400. But on Monday, June 27 all firefighters except for two Type 6 engines were released. With a 70 percent chance of rain in the weather forecast, on Tuesday the local agency decided to replace the Type 1 Team with a Type 4 Incident Commander, two Type 6 engines, and one or two hand crews. The crew(s) had to be re-mobilized on Tuesday after being released. Some aircraft were also assigned on Tuesday.

Weather on Tuesday, the day of entrapment

About 20 minutes before the 2:45 p.m. entrapment the weather at the fire was 95 degrees, 21 percent relative humidity, with a 7 to 10 mph wind out of the south. Although “numerous” people observed dust devils and fire whirls before the large fire whirl formed, there was no discussion about modifying fire suppression tactics. Dust devils can be an indicator of the potential for extreme fire behavior.

Report released on burnover of CAL FIRE engine

The California Department of Forestry and Fire Protection has released what they call a “Green Sheet”, a summary of the burnover of an engine that occurred as it was making a mobile attack on the Pacheco Fire, which eventually burned 341 acres in Calaveras County south of Valley Springs.

****

“SUMMARY

On July 12, 2016, a CAL FIRE Type 3 Model 34 engine (E1) attempted to start a mobile attack toward the head of a vegetation fire. Firefighters deployed two lines, but before they could anchor and start the mobile attack, the main fire and several spot fires converged on the fire engine. One firefighter took refuge in the engine, and one firefighter ran into the green. The engine sustained damage from the fire. Neither firefighter was injured.

CONDITIONS

  • Weather: 89°, 21% relative humidity, winds 9 mph from the west and shifting, taken from the Campo Seco RAWS at 1400 hours.
  • Fuel Type: Approximately two feet tall grass.
  • Topography: Southeast aspect, rolling topography with multiple draws
  • Fire Behavior: Sheeting, fire whirls, spotting

SEQUENCE OF EVENTS

On July 12, 2016, at approximately 1314 hours, CAL FIRE and local government resources were dispatched to a vegetation fire in the vicinity of Langford Pacheco Road and Milton Road in Calaveras County. The initial report on conditions given by the Air Attack at 1329 hours was 15 acres of grass woodland and spotting out in front of the main fire. At 1356 hours, the fire was reported to be 100 acres in size and spotting under the column.

A CAL FIRE engine (E1) arrived at scene at 1345 hours and was assigned Division R, the right flank of the fire. The crew met with a Battalion Chief (BC1) and came up with a plan to create an anchor point and start a mobile attack toward the head of the fire. A second CAL FIRE Engine (E2) and Dozer (D1) were just behind E1.

As E1 crossed through a gate to make access to the fire. E1 stopped in the green and deployed a one inch THY-600 Angus line manufactured by Rawhide Fire, with a 3/8 inch tip for the mobile attack and a reel line to pick up any spot fires. The Captain (FC1) on E1 saw the engine was between the main fire and multiple spot fires. Winds were shifting and the fire behavior was erratic so FC1 from E1 gave the order to pick up the lines so they could move to a better location. As the two firefighters (FF1 and FF2) began to roll up the hose, the main fire and spot fires converged and burned up to the engine. FF1 jumped into the engine while FF2 ran away from the engine into the green, losing his helmet. FC1 lost sight of FF2, and seeing only flames, announced on the tactical frequency that a fire fighter had been burned over. Engine E2 radioed to E1 that they were heading toward them. A large fire whirl was between E2 and E1.

Uninjured, FF2 looked back toward E1 from the green and saw the under carriage of the engine was on fire. FF2 contacted E1 on the radio and told them the engine was on fire. FF1 exited the cab and used the reel line to extinguish the fire under the engine.

Flame impingement caused the airlines above the frame rails to burst. When the air pressure dropped below 60 psi, FC1 was unable to release the spring brake. FF2 ran back to E1. A helicopter dropped water around E1 while D1 constructed line around a portion of E1 to protect the crew. FC1 notified the Incident Commander that all personnel were accounted for and in a good location.

There were no injuries. E1 sustained heat damage to the tires, fenders, lens covers, air brake lines and pump panel.

Review of the 2015 wildfire season in the Northwest

Photo above: Firefighters observe the Cougar Creek Fire southeast of Mt. Adams in southern Washington in 2015. From InciWeb.

The U.S. Forest Service has produced an exhaustive summary and review of the 2015 wildfire season in what they call their Pacific Northwest Region — what the interagency community calls the Northwest Geographic Area — Oregon and Washington.

The report is huge, 281 pages. In addition to general information about the fire activity, it includes sections about weather, air quality, technology, and summaries of 28 fires with 14 of those being covered in greater detail than the others.

The main 281-page report can be be found here (it’s a LARGE file). There is another version they call an “Interactive Story Journal” which provides summary information from the main report as well as interactive web maps, videos, and numerous photos as well as “time-enabled fire progression maps” for selected fires.

Below are some excerpts from the report:

****

Most Severe Fire Season in Modern History

The 2015 fire season in the Pacific Northwest was the most severe in modern history from a variety of standpoints. Oregon and Washington experienced more than 3,800 wildfires (almost 2,300 in Oregon and more than 1,500 in Washington) that burned more than 1,600,000 acres (more than 630,000 acres in Oregon and more than 1,000,000 acres in Washington)—including 1,325 fires representing 507,000 acres on U.S. Forest Service lands (information as of September 30, 2015).

Initial Attack was successful in rapidly containing all but about 119 of these fires. This response represents an almost 97 percent Initial Attack success rate. Approximately 50 of these fire escapes occurred during a ten-day period in mid-August when numerous Large Fires (a wildfire of 100 acres or more in timber or 300 acres or more in grass/sage) were already burning in the Pacific Northwest. During this time, the Northern Rockies and Northern California were also experiencing unusually high numbers of wildfires. This situation limited the ability to rapidly obtain Initial Attack reinforcements as well as almost all types of firefighting resources needed for Large Fires.

Tragedy Strikes

Tragedy struck on August 19 when three U.S. Forest Service firefighters were killed while attacking a fire on private land near Twisp, Washington.

During this severe fire season, approximately 675 structures were lost. While well over 16,000 structures were threatened, most were saved from loss by aggressive suppression actions.

2015 Fire Season Milestones

  • In August, to help support Washington State’s fires, the Emergency Support Function 4 (ESF4) was activated by the Federal Emergency Management Agency (FEMA).
  • The Emergency Conflagration Act—that authorizes the Oregon Office of the State Fire Marshal to mobilize structural firefighters and equipment to assist local resources battling fires—was invoked by the Governor of Oregon on July 30 in response to the Stouts Creek Fire, on August 13 for the Cornet Fire and Windy Ridge Fires, on August 14 for the Canyon Creek Fire, and on August 20 for the Grizzly Bear Complex.
  • The Washington State Fire Service Mobilization Plan is implemented to provide personnel, equipment, and other logistical resources from around the state when a wildland fire or other emergency exceeds the capacity of local jurisdictions. In mid-August, the Chief of the Washington State Patrol authorized such a state-declared mobilization on the Carpenter Road Fire, the Kettle Complex, and the Okanogan Complex.
  • The Pacific Northwest Region had the highest priority in the nation for firefighting resources during these dates: July 25 and 26, August 14-31, and September 8-13.
  • The Pacific Northwest Region was under a Preparedness Level 5 (the highest, most severe level) from August 13 through September 4.
  • The greatest number of uncontained fires occurred on August 18: 25 Large Fires totaling 822,512 acres in the Pacific Northwest Region (105 Large Fires totaling 2.2 million acres nationally).

Weather

The first six months of 2015 were the warmest first six months of any year over much of Oregon and Washington since record keeping began in 1895.

These record-warm temperatures observed during the winter and spring, coupled with below-average precipitation, led to an exceptionally poor snowpack throughout the winter and spring.

From June 1 through September 15, a total of 51,019 lightning strikes were recorded over Oregon and Washington. The average for fire seasons from 2000-2014 through September 15 is 78,775 strikes. While the number of the 2015 strikes was below this average, the background of drought in 2015 enhanced the ability for lightning strikes to ignite multiple fires in short periods of time.
