EPA wants to develop low-cost sensor system to monitor smoke

EPA wildfire smoke sensor challengeThe Environmental Protection Agency has announced an initiative to develop a new low-cost system that could monitor air quality affected by smoke from wildland fires. The existing hardware is large, cumbersome, and expensive, thereby limiting the number of monitoring stations and the data that is available to help officials provide appropriate strategies to minimize smoke exposure.

Below is an excerpt from the EPA’s announcement about what they call the Wildland Fire Sensors Challenge. The three graphics were part of the agency’s news release.

Today, emerging technologies – including miniaturized direct-reading sensors, compact/powerful microprocessors, and wireless data communications – offer the opportunity to develop new systems to quickly gather and communicate air pollution data.EPA wildfire smoke sensor challenge

Wild fires are increasingly common events that produce significant air pollution, posing health risks to first responders, residents in nearby areas, and downwind communities. Also, wild fires are increasing in frequency and intensity, and the fire season is growing longer.  Prescribed fires, which are used to manage ecosystems or reduce risk of wild fires, are typically managed to minimize downwind impacts on populated areas; however, people in close proximity may still be exposed to smoke.  The description “wildland fires” refers to both wild and prescribed fires.

This challenge seeks a field-ready prototype system capable of measuring constituents of smoke, including particulates, carbon monoxide, ozone, and carbon dioxide, over the wide range of levels expected during wildland fires. The prototype system should be accurate, light-weight, easy to operate, and capable of wireless data transmission, so that first responders and nearby communities have access to timely information about local air quality conditions during wildland fire events.

EPA cooperators

The EPA is partnering with several agencies to develop this equipment: Forest Service, National Park Service, National Oceanic and Atmospheric Administration, National Aeronautics and Space Administration, and Centers for Disease Control and Prevention.

However, with the current Administration’s intended massive cutbacks to the EPA and even scattered calls to eliminate the agency, finding the money and staff to bring this idea to fruition is anything but a slam dunk.

Study shows firefighting puts a strain on the heart

A new study conducted in Scotland found that fighting fires could increase the risk of a heart attack.

Wildland firefighter fatality data collected by the National Interagency Fire Center from 1990 to 2014 shows that most of the deaths in that period were caused by medical issues (primarily heart related). The top four categories which account for a total of 88 percent are, in decreasing order, medical issues, aircraft accidents, vehicle accidents, and entrapments. The numbers for those four are remarkably similar, ranging from 23 to 21 percent of the total.

The new UK study suggests that exposure to heat and the physical exertion required to control a fire can cause firefighter’s blood to clot and is putting firefighters at risk of heart attack.

Physical analysis of 19 firefighters in Scotland also found that tackling blazes put a strain on their hearts and worsened the functioning of their blood vessels.

Previous work has shown that firefighters have the highest risk of heart attack of all the emergency services.

The new study reported that a heart attack is the leading cause of death for on-duty firefighters and they tend to suffer cardiac arrests at a younger age than the general population.

Nationwide in the US, around 45% of on-duty deaths each year among firefighters are due heart issues, and researchers at the British Heart Foundation (BHF) and Edinburgh University believe the situation in the UK is comparable, although they did not know the cause.

On two occasions, at least one week apart, they either performed a mock rescue from a two-storey building for 20 minutes or undertook light duties, in the case of the control group, for 20 minutes.

The firefighters wore heart monitors that continuously assessed their heart rate and its electrical activity.

Blood samples were also taken before and after, including measurement of a protein called troponin that is released from the heart muscle when it is damaged.

Those taking part in the rescue had core body temperatures that rose by 1C and stayed that way for three or four hours.

There was also some weight loss among this group, while their blood vessels also failed to relax in response to medication.

Their blood became “stickier” and was more than 66% more likely to form potentially harmful clots than the blood of people in the control group.

Dr Mike Knapton, associate medical director at the BHF, said: “Firefighters routinely risk their lives to save members of the public. The least we can do is make sure we are protecting their hearts during the course of their duties.”

Wildland firefighter fatalities 1990-2014

Four firefighters killed in China

Posted on Categories UncategorizedTags ,

Four firefighters that were working on a wildfire in the Shanxi Province of northern China were found dead Monday April 3. According to local authorities they became entrapped while fighting the fire near Wenjiazhuang Village of Taigu County.

The initial report is that the fire was caused by a villager who was burning paper money while visiting the tombs of relatives before Tomb Sweeping Day, which was on April 4 this year. The custom in China is for people to pay respect to their deceased family members at that time of the year by burning incense and paper money.

The Smokey Generation’s road trip

What is The Smokey Generation? (They offer a description:)

The Smokey Generation is an oral history and digital storytelling project dedicated to collecting, preserving, and sharing the stories and history of wildland fire.  We are passionate about the wildland fire community and culture, celebrating it everyday. We are excited about communicating the beneficial role of fire in the environment and encouraging conversations about how to better use fire as a land management tool. We are committed to giving a voice to wildland fire and fire practitioners in a way that honors our history and proudly demonstrates our relationship to fire and the natural world.  Check us out at: TheSmokeyGeneration.com

We first wrote about the Smokey Generation in 2015.

Looking into the forces that drive wildfires

High Country News has an excellent article written by Douglas Fox that looks under the hood, so to speak, at the science that causes wildfires to burn the way they do. There are forces, unknown until the last decade or two, that are major influences on the spread of a fire, such as the 100 mph flamethrower-like jets of flame that may have contributed to the deaths on the 1994 South Canyon fire near Glenwood Springs, Colorado.

Mr. Fox writes in illuminating detail about state-of-the-art research being conducted by Janice Coen, David Kingsmill, Craig Clements, Mark Finney, Michael Reeder, and Brian Potter, as well as legacy research done by the the U.S. military in the 1940s that provided data on how to design incendiary bombs to burn down many of the buildings in Hamburg, Germany on July 27, 1943 in order to demoralize the workers in Germany’s critical U-boat industry.

Most of the article is about recent research on wildfires, but here is an excerpt about the military’s work in the 1940s in northwest Utah that facilitated the attack on Hamburg by the British that killed at least 42,000 people.

…The U.S. Army’s Chemical Warfare Service had commissioned Standard Oil Development Company to construct a row of steep-roofed European-style apartment buildings. Erich Mendelsohn, an architect who had fled Nazi Germany, specified every detail: 1 1/4-by-2-inch wood battens, spaced 5 7/8 inches apart, to hold the roof tiles; 1-inch wood flooring underlain by 3 1/2-inch cinderblocks, and so on — all to replicate the dwellings of German industrial workers. The wood was maintained at 10 percent moisture to mimic the German climate. Rooms were outfitted with authentic German curtains, cabinets, dressers, beds and cribs — complete with bedding — laid out in traditional floor plans.

Then, military planes dropped various combinations of charges on the buildings, seeking the most efficient way to penetrate the roofs and lace the structures with flame.

Those experiments offered clues on what factors could cause firestorms. And in the years following World War II, scientists would study Hamburg and other bombing raids to derive basic numbers for predicting when a firestorm might form: the tons of munitions dropped per square mile, the number of fires ignited per square mile, and the minimum area that must burn. They concluded that Hamburg’s unusually hot weather set the stage for the firestorm, by making the atmospheric layers above the city more unstable and thus easier for a smoke plume to punch through. Scientists theorized that this powerful rise had drawn in the winds that whipped the flames into even greater fury.

The differences between fighting wildfires in Oklahoma and Kansas

Above: A view of the wildfires in Kansas, Oklahoma, and Texas as seen from a NASA satellite on March 7, 2017. The red areas represent heat.

In some areas of the United States crossing over a state line can bring a person into a completely different wildfire suppression structure. I first noticed the difference between Oklahoma and Kansas while attempting to gather current information about the fires that broke out in both states during very windy Red Flag Warning conditions that began on March 6, 2017. Many fires broke out in both states but the largest became an interstate emergency when several fires burned together straddling the Kansas/Oklahoma border blackening over 700,000 acres.

The larger firefighting organization in Oklahoma, the Oklahoma Forestry Services (OFS), was able to provide much more information to the public about the ongoing situation than the smaller agency in Kansas, the Kansas Forest Service (KSF).

A recent article by Oliver Morrison of the Tribune News Service pointed out one of the differences between the two agencies:

Oklahoma had to learn the hard way that Kansas fights fires unlike almost anywhere else in the U.S., according to George Geissler, the director of the Oklahoma Forest Service.

Instead of reaching out to a single Kansas agency during the Anderson Creek fire last year — which burned nearly 400,000 acres near Medicine Lodge — Oklahoma had to reach out separately to each Kansas county impacted by the fire. Each county gave the fire a different name, Geissler said, and often provided “wildly different” reports about how much damage the fire had done.

So before this year’s fire season kicked off, Geissler took several of his 80 full-time staff members to meet with all five fire people at the Kansas Forest Service responsible for coordinating the state’s response to wildfires. They shared information about how each state handles wildfires.

Below is an excerpt from an article in the Wichita Eagle:

The state’s forest service is the smallest and lowest funded of any in the country – which puts people and property in danger.

Consider the difference in resources and responses between Kansas and Oklahoma:
–The Kansas Forest Service budget in 2016 was about $3 million, with $1 million dedicated to fire service; Oklahoma’s budget was $15 million, with $8 million for fire service.
–The Kansas Forest Service has three trucks and four employees dedicated to firefighting and fire prevention; Oklahoma has 47 fire engines, 47 bulldozers and 84 firefighters.
–On March 6, when the wildfire started, Oklahoma had a plane in the air by 3 p.m. to help firefighters. It was two more days before Kansas could get a rented plane to help in Clark County, after most of the county had burned.

Mr. Morrison reported that “Oklahoma’s total state firefighting budget is about $15 million”.

Kansas budgeted $3,250,985 for the KFS in 2016. Of that total, only 10 percent, or $328,673, came from the state’s general fund, while another $248,384 was generated by technical assistance fees and tree sales. The rest was provided by the federal government (47 percent, or $1,538,660) and state and federal grants (35 percent, or $1,143,268).

In recent years Kansas Governor Sam Brownback, backed by the legislature, has cut taxes in the state.

The New York Times reported on February 22:

Yet Kansas has struggled in the aftermath of the tax reductions, and the state has been rattled by debates about paying for public education and social services. This month, S&P Global Ratings issued a “negative” outlook for its credit rating for Kansas, where the economic growth that Mr. Brownback thought the tax cuts would produce has not materialized. Last summer, S&P downgraded Kansas’ credit rating, to AA-.

It is very likely that the KFS will see even smaller budgets in coming years if the new administration in Washington implements their expressed desire to impose large spending cuts in the federal budget. The President’s proposal is to cut the U.S. Forest Service’s “Payments to State Funds” by 75 percent. The 82 percent provided to the KFS by the feds and grants could be much smaller in the coming years.

But Oklahoma has its own budget worries, with a 10.6 percent cut in funding to the OFS’ umbrella agency, the Department of Agriculture, Food and Forestry after a $1.3 billion state budget shortfall due largely to low energy prices. One of the immediate effects is the closure of four OFS offices.

Kansas has been one of a handful of states that have not become members of interstate wildland fire compacts that provide the means for its member states and provinces to cope with fires that might be beyond the capabilities of a single member. But after two years in a row that saw huge fires burning in the state the legislature passed a bill last week that allows them to become a member of a compact. The one they join could be the Great Plains Interstate Fire Compact comprised of six states and one Canadian province.

In Mr. Morrison’s article he pointed out an issue related to ordering resources for an ongoing fire in Kansas:

During the massive wildfires on March 6, the emergency managers at the state level were using a different system than the emergency managers at the county level, which was a different system than the state Forest Service was using, according to Ross Hauck, who attended the meeting for the Forest Service.

“So the guys in the state emergency operations center were sometimes ordering the same people,” Hauck said.
