Fire vehicle rollovers — how serious a problem is it?

Engine 492 rollover accident

On August 8, 2013 Engine 492 from the Medicine Bow-Routt National Forest and Thunder Basin National Grasslands was involved in a rollover accident on Wyoming State Highway 450 southwest of Newcastle, Wyoming. Three firefighters were injured, one seriously.

The rollover of the U.S. Forest Service fire engine near Clovis, California July 12 that injured five firefighters, one seriously, is another reminder about how frequently wildland firefighters are injured in vehicle accidents.

Here are some snippets of data:

  • A study by Dick Mangan of Blackbull Wildfire Services found that between 1990 and 2009 the leading causes of death of wildland firefighters were: 1. aviation accidents; 2. vehicle accidents; 3. heart attacks/medical causes; and 4. burnovers. From 1990 to 2006, 71 firefighters died in vehicle accidents.
  • The Wildland Fire Lessons Learned Center reported that driving-related incidents was the leading category of incidents that were reported to the Center in 2014.
  • This is a very unscientific data set, but since we started Wildfire Today in January, 2008, we have reported 17 rollovers of fire vehicles that resulted in 44 injuries to firefighters working on or responding to a wildland fire. That does not include non-rollover vehicle accidents, rollovers of heavy equipment (of which there were quite a few), or accidents that occurred in Australia and Canada. Articles on Wildfire Today, 28 of them, tagged “rollover”.

One person was injured when this engine rolled over in 2010 on the Bald Angel prescribed fire on the Wallowa Whitman National Forest near La Grande, Oregon.

What can be done to reduce the number of these injuries and fatalities?


The first thing that is always discussed in accident prevention is training. The most difficult factors to deal with in driving a fire engine are the weight, the center of balance (top-heavy), the physical stress of driving long distances or after a 14-hour shift, and the mental stress of driving an emergency vehicle. All of these are difficult, but not impossible, to train for. Some fire agencies have Engine Academies that actually put trainee drivers behind the wheel, which of course can be extremely beneficial. But it is not easy to train a driver how to react in a split second when they are faced with the sudden decision about possibly hitting the brakes, changing direction, neither of the two, or a combination of the two. Operating a top-heavy 12,000 or 26,000-pound vehicle limits your options. A quick flick of the steering wheel can initiate a rollover.

Driver’s qualifications

When I last worked for the National Park Service (NPS) in 2003 the agency had virtually no specific policy or qualification requirements for the drivers of smaller fire engines, such as a Type 6, other than having a standard state driver’s license. Or if they existed, they were not enforced. A person who had been hired off the street having never driven anything larger than an Austin Mini could be placed behind the wheel of a 15,000-pound top-heavy fire engine.

We checked with the NPS today, and spokesperson Christina Boehle told us that their requirements for driving fire vehicles are on pages 6-9 of Chapter 7 in Interagency Standards for Fire and Fire Aviation (Red Book). This publication includes policies for the Bureau of Land Management (BLM), U.S. Forest Service (USFS), U.S. Fish and Wildlife Service (FWS), and the National Park Service (NPS) and supplements other manuals the agencies have. The Bureau of Indian Affairs does not participate in the Red Book program.

In addition to holding a state driver’s license, all drivers covered by the Red Book have to take a defensive driving course. And, as required by Department of Transportation regulations, all drivers must obtain a Commercial Driver’s License (CDL) for operating vehicles weighing 26,001 pounds or more.

Other than defensive driving, no specific additional training is required by the Red Book for driving fire equipment, except for the BLM and USFS which require “driver training”. Those two agencies also complete paperwork to document driver qualifications.

The Engine Operator position has been removed from the Wildland Fire Qualification System Guide (310-1), but now it can be found in the Federal Wildland Fire Qualifications Supplement. The training requirements listed in the document for the position vary widely among the five federal land management agencies. The BIA does not even recognize the position, and on the other extreme is the BLM which requires seven training courses, only five of which are directly related to operating an engine. The FWS and the BLM require the Engine Academy or a BLM Engine Operator Course, respectively. There is also a Position Task Book for Engine Operator.

Seat belts

It almost seems too obvious to mention, but wearing seat belts is the one thing that every person in a vehicle can do to reduce injuries or save lives in a vehicle accident. Most federal fire land management agencies have policies requiring the use of seat belts.

A study by the Association for the Advancement of Automotive Medicine found that in 7.6 percent of fire truck crashes that were reported to the police some of the occupants were not wearing seat belts, and 74 percent of the fatal crashes involved the non-use of seat belts.

Seat belt use in fire truck crashes

Supervisors at all levels need to proactively ensure that firefighters in all types of vehicles, including crew carriers, wear seat belts.


You may have seen Austin Dillon’s horrific-looking crash in the July 5, 2015 NASCAR race. His car became airborne at about 180 mph and crashed into the fence, coming to an immediate stop. Then when it appeared to be over and the remains of the car were upside down, an out of control car hit it with force, causing it to spin around several times on its roof.

The car was barely recognizable as a car after the crash. The front one-third and the rear one-third were gone, but the integrity of the driver’s compartment and his seat remained intact. The only object in the interior that came loose was the radio. Mr. Dillon walked away with only a few bruises.

This shows what can be done to prevent injuries in a very serious vehicle crash. It is not practical to harden the cab of a fire engine to the degree seen in NASCAR, but there are steps that can be taken to prevent the roof from collapsing in a rollover, such as was seen when U.S. Forest Service Engine 392 rolled over in Wyoming in 2013 (see photo above).

The wildland fire agencies should fund research conducted by engineers to determine how to prevent the passenger compartments in their fire engines from collapsing in accidents.

Ensure that fire vehicles are not overweight

In the 1990s one federal land management agency was accepting new Type 6 engines from manufacturers that exceeded the Gross Vehicle Weight (GVW) the day they were delivered after being filled with water.

Adding thousands of extra pounds beyond the GVW to an already top-heavy vehicle can make it difficult to control, especially when making an evasive maneuver or a quick stop. The additional weight is also hard on suspension systems and can cause premature failure of various components.

While federal land management agencies have been guilty of overweight fire trucks, some local fire departments have had the same problem. Too many departments take a Ford F-150 or F-250 and add a very heavy tank and pump package, exceeding the manufacturer’s designed GVW.

A study by the National Institute for Occupational Safety and Health documented some extreme cases, including one where a military surplus tanker designed to carry gasoline was transporting 1,200 gallons of water primarily off road, which put the weight of the loaded vehicle approximately 7,000 pounds over the cross-country weight rating.

I’m thinking the BLM did not waste a lot of money producing this 36-second public service announcement, but I like it, and it could be effective. Nicely done, BLM!


(UPDATE at 11:18 a.m. PT, July 1, 2015)

After we posted the video, Kevin Conran of the BLM left this comment:

Thank you for the compliments on our PSAs. As you surmised this was very low cost to produce. It was actually produced by a local high school student. We hosted a contest among the high school speech/communications classes and challenged them to produce PSAs aimed at reaching their age group.

USFWS employee receives award for suggestion to track firefighters with transmitter collars

Barton Rye award

FWS Branch Chief John Segar presents National Safety Award to Barton Rye Credit: Josh O’Connor, USFWS

Tallahasee, Florida – On May 7, the U.S. Fish and Wildlife Service (FWS) presented its second annual National Fire Safety Award to Barton (Bart) Rye, Prescribed Fire/Fuels Technician from St Marks National Wildlife Refuge for a simple suggestion that helped direct a lost firefighter to safety during a prescribed fire.

The Award, presented by John Segar, FWS Chief, Branch of Fire Management from the National Interagency Fire Center, recognizes Rye for his innovative use of Global Positioning System (GPS) technology to more easily map, track and monitor the location of multiple firefighters, vehicles, and aircraft during large burns on the 70,000-acre refuge.

Rye suggested that his fire crew on foot and all-terrain vehicles (ATVs) carry GPS transmitter collars, like those worn by his hunting dogs, so that up to ten resources could be tracked in real-time by a Burn Boss on a single hand-held receiver. ATVs and dozers on southeastern forests commonly become high-centered on hard-to-spot stumps in heavy vegetation where they cannot be readily seen by others, risking the loss of life and/or equipment during fires.

The refuge first tested the use of the collars last spring. When a firefighter unfamiliar with southeastern terrain walked into a sawgrass pond while igniting a burn and becoming disoriented in knee-deep water with grass over his head, the GPS device allowed the Burn Boss to verbally direct the firefighter out of harm’s way. In February, a helicopter working a 3800-acre burn carried a collar to allow immediate location of the aircraft in case of an accident.

“Bart’s initiative added a level of safety that wasn’t there before and may very well lead to national implementation,” said Segar. “This system is off-the-shelf and simple to operate.”

The Refuge purchased two hand-held receivers — one each for a Burn Boss and Firing Boss — and a transmitting collar for each prescribed fire crew member. A single transmitter and hand-held receiver together cost about $500.

St. Marks National Wildlife Refuge along Florida’s Gulf Coast conducts 40-50 prescribed burns annually, averaging 300-400 acres each, to reduce the risk of wildfire and maintain fire-resilient landscapes.

2014 wildland fire incident summary

The Wildland Fire Lessons Learned Center has released a summary of incidents that occurred on wildland fires in 2014. The document only includes incidents that were reported to the LLC. Unfortunately the LLC does not define the term “incident” but it appears to be a serious injury or accident on a wildland fire, perhaps including serious near misses.

Below we have a few graphic highlights. The complete report can be found HERE.

Grass fire tactics and safety

In a comment regarding the earlier article about the fires in Logan County, Oklahoma, Dick suggested some videos that shed light on the subject of fighting fire in grass —  “Attack from the Black” and “Oh, it’s just a Grass Fire”. We found those videos.

The first one, below, is “Attack from the Black”, which covers the tactics and safety of suppressing grass fires. Produced by the Texas Forest Service, it is actually a series of six videos, with each one being one to seven minutes long. It was uploaded to YouTube in 2011. If you play the one below, it will automatically keep transitioning to the next until you have watched all six.

The next video is “Oh, it’s just a Grass Fire”, uploaded by the Wildland Fire Lessons Learned Center in 2011. Here is how it is described:

Because grass fires often burn in short, light fuels, some firefighters may tend to encounter them with their “guard down”—without taking adequate safety precautions. Using lessons learned from actual grass fire incidents, this video illustrates why such a mindset can have disastrous outcomes. Don’t believe it? Hear a severely burned firefighter explain what he now wants you to always remember.

Still another revision of safety zone rule

safety zone

A safety zone constructed on a wildfire in 2014. Is this like a tactic used in the Vietnam war? “We had to destroy the village in order to save it.” (Screen grab from the video below.)

In May of this year Bret Butler, who works in the Fire Behavior Research Work Unit at the Fire Sciences Laboratory in Missoula, Montana, issued a new rule on the size of a safety zone. Mr. Butler revised it two months later in July, and after an additional four months he changed it still again in November.

The calculation of the size of a safety zone is somewhat complex for a firefighter in the heat of battle, and these various guidelines can only be used if the firefighter on the ground is carrying the latest written directions about how to do the math. While it is laudable that researchers are working to improve the safety zone guidelines, changing them every two to four months is too confusing.

In the video (webinar) below the new revision is discussed in detail in the one hour and 15 minute presentation, including questions. (A three-minute executive summary version would be very much appreciated.) This new November, 2014 version of the “Preliminary Proposed Safety Zone Rule” appears at 44:00. The fact that it is called both preliminary and proposed leads us to believe there will be still more changes in the near future.

Below is the description of the December 2, 2014 webinar, presented by Mr. Butler.

Current safety zone guidelines for wildland firefighters are based on the assumption of flat ground, no wind, and radiative heating only. Recent measurements in grass, shrub and crown fires indicate that convective heating can be significant especially when wind or slope are present. Measurements and computer modeling supports this finding and suggests that convective energy transport should be considered when assessing safety zone effectiveness any time wind or slope is present. The results of the research are presented along with recommendations for modifications to current safety zone guides.
