The National Fire Protection Association (NFPA) has received a large grant from the Federal Emergency Management Agency to transform its classroom-based wildfire risk reduction training into a digital learning experience for Americans living and working in the wildland/urban interface (WUI).
The organization will develop three training programs — for homeowners, business owners, and public safety personnel. They will cover WUI fire mitigation practices using interactive web-based training and engaging simulations in a 3-D virtual environment. The training modules will be experiential, a process of learning through experience such as hands-on or simulations.
Some of the content from an existing conventional class, Assessing Structure Ignition Potential from Wildfire, will be incorporated into the new experiential format. The two-day course is based on fire science research into how homes and other structures ignite during wildfires and covers wildfire behavior, structure exposure, and the concept of the Home Ignition Zone. Attendees learn how to analyze wildfire risks to structures and provide actionable advice to property owners through an activity-rich curriculum.
The transformation project will be conducted in partnership with the Insurance Institute for Business & Home Safety, an independent, nonprofit, scientific research and communications organization, and overseen by a technical advisory panel of experts.
Michele Steinberg, Manager of NFPA’s Wildfire Division, said work based on the $950,000 FEMA grant began in September, 2020. “We anticipate having the main training module deliverable available by around October 2021, with additional elements being added through the first three quarters of 2022,” she said.
The NFPA has also received two other FEMA Assistance to Firefighter Grants grants to study the effectiveness of fire investigator personal protective equipment and to develop a strategic roadmap for the fire service while transitioning from fluorinated foam usage to fluorine free foam technology.
Vice President Biden at the memorial service for the Granite Mountain Hotshots in 2013: “Firefighting is not what they did — it is who they were”

With a new administration taking the reins of the federal government January 20, some may be thinking about what changes, if any, will affect wildland firefighting. Of course it is dangerous to attempt to predict what any government official will do, but in this case President Elect Joe Biden has a lengthy track record even before he served as Vice President for eight years under the Obama presidency.
Vice President Biden spoke at the memorial service July 9, 2013 in Prescott Valley, Arizona, for the 19 members of the Granite Mountain Hotshots who died June 30, 2013 on the Yarnell Hill Fire. From the C-SPAN recording, we made a video clip of his remarks and the slide show that followed featuring the 19 men. You can see the entire two-hour service at C-SPAN.

At Prescott Valley Mr. Biden showed tremendous empathy and appreciation for the deceased men, their families, and firefighters in general, saying, “All men are created equal, and then a few became firefighters,” and, “They were heroes long before we knew their names.” Few public servants would be capable or have the desire to exhibit the degree of compassion for firefighters showed by Mr. Biden. Most people will find themselves choking up while listening to his sympathetic words. Cameras caught people in the audience wiping away tears.
Vice President Biden also spoke September 12, 2009 at the memorial service for the two firefighters killed on the Station Fire near Los Angeles, Tedmund Hall and Arnaldo Quinones.
In 2013 Vice President Joe Biden and Attorney General Eric Holder presented the Medal of Valor to 18 firefighters and police officers for exhibiting exceptional courage. The Vice President, a former Chairperson of the Congressional Fire Services Caucus, made some very meaningful remarks, some of which appeared to be unscripted. Here is a brief excerpt:
There’s something special about firefighters and cops……. You all share — you’re all crazy, God love you — you all share a selflessness that is not easily explained, a commitment to your fellow man that’s rare, bravery that inspires, literally inspires almost everyone that hears about it……. Being a firefighter or police officer is not what you do, it’s who you are….. There’s something about ya’ll. You can smell it when you’re 10, you’re 12, you’re 15. And God we’re lucky for it man. I marvel at what makes them tick. I marvel at what makes them tick.
But showing compassion and empathy does not guarantee future action or passing legislation when necessary.
The Obama/Biden administration worked with Congress to address climate change in many ways, including participating in the 2015 Climate Agreement. During the last four years the U.S. has withdrawn from the Agreement and taken other actions to reverse previous progress, but Mr. Biden has said he will make dealing with climate change an important priority, will again honor the agreement, and has an ambitious goal of net-zero greenhouse gas emissions by 2050. The large majority of respected climate scientists have concluded that human-caused climate change has greatly affected our weather. The higher temperatures and bouts of drought and extreme weather have resulted in lower fuel moistures and extreme wildfires that are very difficult to suppress. At stake are lives, private property, health of the population, and natural resources. Lack of action to slow climate change is not a reasonable option.
Here are some examples of Mr. Biden’s record on firefighter issues documented by the International Association of Firefighters:
As vice president, Mr. Biden was tasked by President Obama as the administration’s point-person on first responder issues.
During his time in the Senate, he played a leadership role on nearly every piece of legislation introduced affecting fire fighters.
Early in his Senate career, Mr. Biden championed the Public Safety Officers Benefit (PSOB) program, which provides death benefits to the families of fallen fire fighters. He later introduced and passed legislation to increase PSOB benefits from $150,000 to $250,000, and indexed it to inflation so the benefit is now $340,000.
Senator Biden helped create the Assistance to Firefighters (FIRE Act) and Staffing for Adequate Fire and Emergency Response (SAFER) grant programs, and consistently advocated for robust funding.
As vice president, Mr. Biden helped push through the Zadroga 9/11 Act to provide healthcare and compensation to those fire fighters who participated in the 9/11 response and recovery efforts. (Video of Jon Stewart advocating for the extension of the Act in 2019.)
William Shakespeare wrote in his play The Tempest, “What’s past is prologue.” We can safely assume that in his administration, Mr. Biden will continue to care about firefighters. But he can’t pass legislation — he will need the cooperation of Congress, which has found it difficult move any kind of bill in recent years.
Perhaps Mr. Biden will have more luck than previous presidents due to having served in the Senate for 36 years and his relationship with Mitch McConnell, who may still be the Majority Leader in the Senate going forward. Here is an excerpt from an article at Firechief.com:
In his book “The Long Game: A Memoir,” McConnell stated that trying to deal with then-President Obama was impossible. “[Obama] acted like a professor every time we tried to discuss legislation. The first 45 minutes was always a lecture about how and why we were wrong,” McConnell wrote. On the other hand, McConnell loved dealing with Biden. “Joe would come into a meeting and say, this is what I need, and this is what I understand that you need. Is there any way to work out a deal here?”
Steven Metheny’s falsification of records for a helicopter led to the deaths of nine firefighters and crew members in 2008
Photo credit: Carson Helicopters
Steven Metheny, 50, the former Vice President of Carson Helicopters has requested compassionate release from prison because he fears he will contract COVID-19 while serving time in the federal prison in Lompoc, California.
He filed the request in October and on November 2 Assistant U.S. Attorney Amy Potter wrote in a response, “The mere existence of COVID, without more, is not sufficient to justify compassionate release.” Potter argued that Metheny’s weight is the only eligible health condition that increases his risk of COVID-19. “But, obesity alone should not result in defendant’s release,” Potter wrote.
Mr. Metheny’s falsification of records for a Sikorsky S-61N helicopter under contract to the U.S. Forest Service led to the deaths of nine firefighters and crew members in 2008.
Mr. Metheny was accused of falsifying performance charts and the weights of helicopters his company had under contract to the U.S. Forest Service for supporting wildland fire operations. As of a result of his fraud, a Carson helicopter crashed while trying to lift off with too much weight from a remote helispot on the Iron 44 Fire on the Shasta-Trinity National Forest near Weaverville, California in 2008. He was sentenced to 12 years and 7 months in prison in 2015 for attempting to defraud the government out of more than $32 million and has been serving time in Lompoc, California.
Nine people were killed, including the pilot-in-command, a U.S. Forest Service check pilot, and seven firefighters. The copilot and three firefighters were seriously injured.
Mr. Metheny went to great lengths after the crash to attempt to conceal the fraud. When he knew that investigators would be examining the company’s operations, he directed other employees to remove weight from other similar helicopters, including taking off a fuel cell and replacing a very heavy battery with an empty shell of a battery. Some of the employees refused to participate in that deception, with one explaining that he was done lying about the helicopter’s weight.
During the trial in 2014 defense lawyer Steven Myers argued that the helicopter pilot could have avoided the crash by doing a standard maneuver on takeoff, where the pilot hovers and checks his gauges.
Judge Aiken who presided over the trial dismissed that argument, noting her father had flown helicopters in the Korean War, crashing 13 times. “Whether the gauges were right or not, the pilot didn’t have the right information,” Aiken told Mr. Metheny.
In June, 2020 the same judge refused to reduce Mr. Metheny’s sentence when he argued he had ineffective counsel. He said he would not have pleaded guilty in 2014 if his attorney had told him that crash victims were going to be allowed to testify at his sentencing, or that he’d be ordered to repay tens of millions of dollars in restitution upon release from prison. Judge Aiken called Mr. Metheny’s claims that his defense lawyer made false promises “palpably incredible.”
The next hearing on Mr. Metheny’s motion for compassionate release is a phone conference scheduled for November 13 in U.S. District Court in Eugene, Oregon.
Killed in the crash were pilot Roark Schwanenberg, 54; USFS check pilot Jim Ramage, 63; and firefighters Shawn Blazer, 30; Scott Charlson, 25; Matthew Hammer, 23; Edrik Gomez, 19; Bryan Rich, 29; David Steele, 19; and Steven “Caleb” Renno, 21. The copilot and three other firefighters were seriously injured.
Thanks and a tip of the hat go out to Pat and Kelly.
The accident occurred July 7, 2020 on the Polles Fire west of Payson, Arizona
Bryan Jeffery “BJ” Boatman
On July 7, 2020 a UH-1H helicopter crashed while transporting supplies to firefighters who were spiked out (camping) while working on the Polles Fire about 10 miles west of Payson, Arizona. The only person on board, pilot Bryan Jeffery “BJ” Boatman, 37, of Litchfield Park, Arizona was killed. We send our sincere condolences to the family and friends of Mr. Boatman, and to the forestry technicians who were at the fire.
The brief preliminary report issued by the National Transportation Safety Board (NTSB) did not mention any obvious causes for the crash, which happened while transporting firefighters’ equipment in an external sling load. Multiple personnel on the ground observed the helicopter flying erratically until finally “it entered a steep nose up attitude and then descended rapidly,” according to the report. Fire personnel saw no signs of fire before the crash and all major structural components of the helicopter were accounted for at the accident site.

BJ was born on June 8, 1983 in Provo, Utah. He was a third-generation pilot and worked alongside his parents to build their company, Airwest Helicopters of Glendale, Arizona.

The helicopter, N623PB, serial number 64-13689, was manufactured in 1964. It is a UH-1H registered to Aero Leasing in Glendale, Arizona, the same city where Air West Helicopters is located.

In addition to the preliminary report released by the NTSB, a 23-page facilitated learning analysis (FLA) was commissioned by the U.S. Forest Service.
The FLA is solely devoted to analyzing the response to the accident — the Incident Within an Incident and the actions taken in the following days. It does not address what caused the helicopter to crash. The report found very little to criticize and praised most of the actions that were taken. It goes into quite a bit of detail about how the fire’s Incident Management Team handled the emergency response during the first few hours, as well as organizing over the next several days to care for BJ’s family and the forestry technicians that were witnesses to the crash or were otherwise affected.
Anyone who could in the future find themselves in a similar unfortunate situation would benefit from reading this FLA. Firefighting is dangerous, in the air and on the ground, and others will have to walk this same path.
During a 49-day period that began July 7, 2020 there were six crashes of firefighting aircraft — three helicopters and three air tankers. In addition, three members of the crew of a C-130 from the U.S. died when their air tanker crashed January 23, 2020 while fighting a bushfire in New South Wales, Australia.
Below is the text from the narrative portion of the three-page NTSB report. The complete report which will analyze the cause, might be released within the next year.
“On July 7, 2020, about 1213 mountain standard time, a Bell/Garlick UH-1H helicopter, N623PB, was destroyed when it was involved in an accident near Payson, Arizona. The pilot was fatally injured. The helicopter was operated as a Title 14 Code of Federal Regulations Part 133 external load flight.
Figure 1: Depiction of helicopter flight path based on witness statements. From the NTSB preliminary report.
“The helicopter was owned by Airwest Helicopters LLC and operated by the United States Forest Service at the time of the accident. According to witnesses, the helicopter was transporting supplies using a long line for a hotshot firefighting crew that were repositioning on the ground. The pilot transported three loads to the new destination uneventfully prior to the accident and had been using an indirect route to the north to avoid a fire area (Figure 1). While transporting the fourth load, witnesses observed the helicopter begin to fly erratically while en route to its destination. During this time, a witness stated that he observed the helicopter enter a high nose-up pitch attitude and the external payload began to swing. The helicopter then displayed irregular movements for several seconds before the external payload settled and the helicopter appeared to stabilize. However, after about 3 seconds, multiple witnesses observed The witnesses did not observe the helicopter on fire during the accident flight, nor did the pilot report any anomalies over the helicopter crew’s common air-to-ground radio frequency or any other assigned frequencies for the fire.
“The helicopter wreckage came to rest about 0.5 nm north of its drop off destination, oriented on a heading of 074° magnetic and was mostly consumed by postcrash fire. All major structural components of the helicopter were accounted for at the accident site. The helicopter’s external payload was found 123 ft southeast of the main wreckage.
“The wreckage was retained for further examination.”

Originally published by the Centers for Disease Control and Prevention
While research has not yet been conducted on all the hazards and risks associated with the wildland firefighting job, the National Institute for Occupational Safety and Health (NIOSH) is asked numerous questions about the hazards of fighting wildland fires. This blog is designed to answer some of those questions.
What Is in Wildland Fire Smoke?
Wildland fire smoke is a mixture of gases and particles such as carbon monoxide (CO) and respirable particulate matter (PM) that may cause short- and long-term health effects. Wildland firefighters can be exposed to smoke at wildfires and “prescribed” fires (planned and intentionally ignited low-intensity fires). The contents of and exposure to wildfire smoke can vary greatly throughout the day depending on the vegetation type, fire behavior, and meteorological conditions. Research has shown that wildland firefighters have been exposed to gases and particles such as CO and PM above the occupational exposure limits during both wildland and prescribed fires. While burning vegetation is the primary exposure of concern for wildland and prescribed fires, when fires burn in the wildland urban interface (WUI, where wildland vegetation and urban areas meet) the smoke may contain compounds that are more similar to what structural firefighters encounter. Wildland firefighters will often suppress these fires and may be exposed to some of the hazardous compounds of WUI smoke such as volatile organic compounds (VOCs), flame retardants, and polycyclic aromatic hydrocarbons (PAHs). However, wildland firefighters do not have the benefit of wearing some of the personal protective equipment (PPE) typically used in a structural response (e.g., self-contained breathing apparatus [SCBA], turnout gear) that could provide protection from these compounds. Additionally, wildland firefighters may be exposed to smoke at firefighting base camps (incident command posts) where they eat and rest while off-duty.
What Do We Know About the Health of Wildland Firefighters?
Cardiovascular and Lung Health
In the past decade, several studies have linked exposure to wildfire smoke to short-term health effects, such as increases in inflammation and respiratory effects, for example, lung function decline.[i] However, these studies have only examined the health effects across a few shifts or a single fire season. It is not clear if these adverse health effects continue after fire season and whether they worsen after several seasons of fighting fires. Researchers suspect that exposure to particulate matter and other contaminants from wildfire smoke, heavy physical exertion, existing health and behavior risk factors, and cardiovascular strain could contribute to sudden cardiac events for wildland firefighters. Recent research indicated that wildland firefighters may be at an increased risk of mortality from cardiovascular disease and lung cancer than the general public from career exposure to wildfire smoke.[ii]
COVID-19
The strenuous work, long work shifts, close living and working conditions, limited access to hygiene supplies, and a workforce that responds to incidents all over the country on short notice to wildland fire incidents may be conducive for the transmission of infectious diseases, including SARS-CoV-2. Exposure to air pollutants in wildfire smoke can irritate the lungs, cause inflammation, alter immune function, and increase susceptibility to respiratory infections, possibly including COVID-19.[iii] In addition to potentially making firefighters more vulnerable to getting COVID-19, inflammation in the respiratory tract due to wildfire smoke might also increase the risk of developing more severe outcomes for those with COVID-19.[iv] Wildland firefighters should implement the recommendations described in the CDC’s FAQ for Wildland Firefighters to prevent infection and spread of COVID-19.
Heat-Related Illness and Rhabdomyolysis
Due to the nature of their work, firefighters are at risk of developing severe heat-related illness (such as heat stroke) and rhabdomyolysis (muscle breakdown).[v],[vi] Delays in diagnosis and initiating treatment of these illnesses increase the risk of permanent muscle damage. Since 2010, 62 cases of severe rhabdomyolysis among wildland firefighters have been reported to a passive surveillance system designed to capture fatalities and certain types of injuries and illnesses including rhabdomyolysis. The actual number of cases is likely higher due to underreporting and inconsistencies in reporting requirements and systems. Prior to 2010, no cases were reported.
Hearing
Wildland firefighters work around power tools and heavy equipment that produce noise levels that are hazardous to hearing. In addition to hearing loss, noise exposure may also cause tinnitus (ringing/buzzing in ears), increased heart rate, fatigue, and interfere with verbal communication. Researchers from NIOSH and the United States Forest Service (USFS) evaluated personal noise measurements on 156 wildland firefighters conducting various training and fire suppression tasks, and reported that 85 of the 174 measurements were above the NIOSH maximum allowable daily dose[vii]. A follow-up study showed use of hearing protection was mixed; while almost all the wildland firefighters were aware of the noise in their environment and potential risk, very few were enrolled in hearing conservation programs.
What Are NIOSH Researchers Doing to Better Understand Exposures and Health Effects?
NIOSH is currently conducting research to understand the exposures and health effects of firefighters suppressing wildland and WUI fires. NIOSH researchers and collaborators at the US Forest Service and Department of the Interior have finished the second year of a multi-year study investigating exposures and health effects among six federal 20-person firefighting crews. The primary goal of this study is to measure exposures in the wildland fire environment and examine associations between those exposures and changes in lung, cardiac, kidney, and hearing function during each fire season and the off season over multiple fire seasons. This study has been paused in 2020 due to COVID-19 but is expected to resume.
To understand exposures and health effects faced by WUI firefighters, NIOSH is working with researchers from the University of Arizona and University of Miami to expand an existing collaborative research study (the Fire Fighter Cancer Cohort Study) to collect data regarding exposures from WUI fire incidents during the 2019 and 2020 fire seasons. Characterizing the types of chemicals, as well as the routes and levels of exposures, will help us understand health risks for wildland firefighters.
NIOSH is also in the process of developing a study assessing self-reported exposures to wildfire smoke and COVID-19 health outcomes among wildland firefighters. Additional information about this research will be available soon on the NIOSH Fighting Wildfires Page.

At least 219 U.S. Forest Service personnel involved in firefighting have tested positive for COVID-19 so far this year, according to Stanton Florea, a Fire Communications Specialist for the agency.
Since early March, 141 employees of the California Department of Forestry and Fire Protection have tested positive, said Alisha Herring, Education, Outreach, and Engagement Officer for the agency on November 5.
Jim Gersbach, Public Information Officer for the Oregon Department of Forestry, told Wildfire Today that “among all wildland firefighters in Oregon this summer – not just ODF personnel — seven tested positive.”
Wildfire Today has also learned from other sources that more than half a dozen members on one of the teams managing wildland fires have also tested positive in recent weeks. In the interests of privacy we will not identify the team.
Two months ago the Forest Service reported 122 positive tests. The Bureau of Land Management had 45 which at the time included one person in critical condition and one fatality from the virus.
No deaths were reported among fire personnel in the U.S. Forest Service, Oregon Department of Forestry, or CAL FIRE.
As this was written at 4:17 p.m. MST November 5, the National Park Service and the Bureau of Land Management had not provided updated numbers of their fire personnel that have tested positive.
For the most part wildland firefighters have adapted to the reality of working with the continuing threat of COVID-19. Here are examples of mitigation measures taken by wildland fire organizations:
Physical distancing and wearing face coverings.
Daily self-assessments.
Only one person from a unit or module attend physical briefings; or,
Briefings by radio, rather than in large groups.
Distributed Camps and multiple staging areas, having a much smaller number of people than traditional Camps or Incident Command Posts. This puts an added burden on the Logistics section, but is safer for all.
Some crews have become virtually self-sufficient for days at a time, carrying enough equipment and supplies to prepare their own meals.
“Module as One”, means a crew is treated as a family, not individuals. When together and away from others, they would not have to physically distance or wear masks.
Crew Time Reports (CTR) showing the hours worked each day can be submitted and approved electronically.
Demobilization documents can also be emailed and signed remotely.
Email incoming resources a short in-brief with PDF maps, digital CTRs, digital time sheets.
Use QR codes to provide access to maps and Incident Action Plans.
Use a Unit Log to record all close human contacts outside of the Module As One, in order to facilitate contact tracing if someone tests positive.
Establish trigger points around COVID-19 for PPE, sanitation, and holding capacity. Don’t order more resources than you can sustain.
When feasible, Air Tankers work from a home base and return to that location at the end of each day. Before this year, especially when there have been less than 24 large air tankers on contract, they would often be repositioned for days at a time, frequently staying overnight in different cities.
Fire officials are discovering that some of the measures above might continue to be used after the pandemic since they can enhance efficiency and productivity.
One high-ranking fire official who spent much of the summer on fires told us that some incident management teams (IMT) are applying the mitigation measures to a greater extent than others. The Alaska IMT for example, is very careful and requires that incoming personnel from the Lower 48 states be tested before they travel and after they arrive in Alaska. Some teams are adamant about wearing face coverings while others are not.
There are anecdotal reports that the mitigation measures taken this year have reduced the occurrence of diseases that are sometimes common at large fires, such as respiratory and digestive disorders.
