Research: global wildfires did not kill the dinosaurs

Contrary to what other researchers concluded, a new study revealed that an asteroid that hit the Earth 65 million years ago on the Yucatan Peninsula in Mexico did not cause global wildfires that wiped out the dinosaurs. The first study led scientists to think that the impact raised temperatures to 1,000 degrees C, igniting global wildfires that killed most organisms.

The latest research team from Royal Holloway, University of London, led by Claire Belcher, concluded that “…the amounts of thermal radiation released by the impact of an asteroid with the Earth 65 million years ago, were not as significant as previously thought, and the energy component of the K-T event was not responsible for the extinctions seen at this time”.

Public Service Announcements about wildfire

An organization in Nevada has produced and released nine 31-second public service announcements about wildfire evacuation and defensible space. The list is HERE, and below is an example:

Colorado state Senator has second thoughts about bill that would have limited agricultural burning

A Colorado state Senator who introduced a bill that would allow county commissioners to ban agricultural burning and campfires when fire danger is high has had second thoughts and now wants to pull the bill. Senator Larry Crowder from Alamosa, under pressure from farmers, said Friday that there could be a possibility of county officials over using the power. The bill already passed the House by a 36 to 27 vote on February 14.

Research: titanium golf clubs can start fires

fire started by golf club

In August, 2010 golfers reported that  a 12-acre fire ignited when a golfer, whose ball was in the rough, struck a rock with his club, causing sparks which started the fire. It took hand crews, helicopters, and 150 firefighters to put out the fire at the Shady Canyon Golf Club in Orange County, California.

Following that fire and another one that also may have been started by a golf club, fire investigators in Orange County asked researchers at the University of California to investigate the issue. The report below is from UC Irvine:

“Irvine, Calif., March 19, 2014-Titanium alloy golf clubs can cause dangerous wildfires, according to UC Irvine scientists. When a club coated with the lightweight metal is swung and strikes a rock, it creates sparks that can heat to more than 3,000 degrees Fahrenheit for long enough to ignite dry foliage, according to findings published recently in the peer-reviewed journal Fire and Materials.

Orange County, Calif., fire investigators asked UC Irvine to determine whether such clubs could have caused blazes at Shady Canyon Golf Course in Irvine and Arroyo Trabuco Golf Club in Mission Viejo a few years ago.

“One fire almost reached homes before they stopped it. This unintended hazard could potentially lead to someone’s death,” said chemical engineering & materials science professor James Earthman, lead author on the paper. “A very real danger exists, particularly in the Southwest, as long as certain golf clubs remain in use.”

He suspected that the titanium heads on some clubs designed for use in “the rough” – natural areas off irrigated fairways – could be to blame for the fires. Most golf clubs have stainless steel heads. However, a significant number being manufactured or in circulation have a titanium alloy component in the head. Such alloys are 40 percent lighter, which can make the club easier to swing, including when chipping errant balls out of tough spots. In Southern California, those spots are often in flammable scrub brush.

The researchers painstakingly re-created in the lab course conditions on the days of the fires. Using high-speed video cameras and powerful scanning electron microscope analysis, they found that when titanium clubs were abraded by striking or grazing hard surfaces, intensely hot sparks flew out of them. In contrast, when standard stainless steel clubs were used, there was no reaction.

“Rocks are often embedded in the ground in these rough areas of dry foliage,” Earthman noted. “When the club strikes a ball, nearby rocks can tear particles of titanium from the sole of the head. Bits of the particle surfaces will react violently with oxygen or nitrogen in the air, and a tremendous amount of heat is produced. The foliage ignites in flames.”  ”

Fire whirl full of tumbleweeds

This very impressive fire whirl was captured on video March 14 at the Rocky Mountain Arsenal near Denver, Colorado during a prescribed fire. The swirling wind swept up tumbleweeds, some of them burning, and created a problem for firefighters. It was posted on YouTube by Bellevue Wildfire.

Ten things I think I think

As the Aerial Firefighting conference winds down at McClellan Air Force Base in Sacramento, these are the 10 things I think I think (with apologies to Peter King).

1. I think 150 scoops in a water-scooping CL-215T in a 13-hour flying day is pretty amazing. That’s what a pilot from Spain told me he accomplished on a fire one time before his agency changed the policy of no limit on the number of hours flown to nine hours per day. The average number of scoops he usually completes now is 10 per hour.

basket2. I think the extraction/insertion upside down folding “umbrella” demonstrated by Aviation Safety Tactical today for hauling personnel by helicopter to a remote area is pricey at $75,000 each. A representative said the price will come down if it ever goes into mass production.

3. I think it will be interesting to see if the only purpose-built Type 1 air tanker, the Be-200, ever obtains FAA and Interagency Air Tanker Board approvals. The Be-200 is the Russian-made, jet-powered, 3,170-gallon, amphibious water scooping air tanker made by Beriev. The manufacturer and an American company headed by David Baskett are still trying to push the approval through the bureaucracy. We need more purpose-built air tankers.

4. I think it is surprising that with the highly publicized California drought the two hotels I stayed in while in Sacramento both had high-volume shower heads — the large saucer-shaped versions that Holiday Inn Express advertises on billboards. One community not far from here is requiring residents to reduce their water consumption by 25%, under threat of large fines if they don’t comply.

5. I think I was lucky to be routed into the expedited screening security line at the Rapid City Airport. I was pleased that I did not have to remove the boarding pass from my pocket, take off my belt and shoes, or remove my computer from my carry-on while it went through the machine.

6. I think I miss the days when on a flight we at least were given a tiny bag of peanuts. It is only a distant memory now. How long will it be before they start charging for a soda pop or a glass of water?

7.  I think hotels need more electrical outlets. In order to plug in the coffee maker, I had to crawl under a table and unplug the TV or a lamp that I needed, or carry the machine across the room where there was a vacant outlet. Then there’s other devices that also need electricity, like the computer, camera battery charger, and the cell phone.

8.  I think that since the Lions Gate Hotel at McClellan totally screwed up my reservation, telling me I had none in spite of the printout I showed them of the email confirming the damn thing, I will never go near that hotel again.

9.  I think it is impressive that to get ready for the grid test of their BAe-146 air tanker, Minden Air Corp obtained and pounded into the earth 3,155 four-foot “T posts” to hold the cups that will catch and measure the retardant. The grid test is a requirement to obtain certification from the Interagency Air Tanker Board. The retardant caught in the cups, which are spread over a large area, can determine the distribution of the retardant.

10. Requiring suits and ties for a fire conference is stupid. Hey Tangent Link and conference chair retired Admiral Terry Loughran formerly of the Royal Navy — the 1950s called and they want their “dress code” back.

Throwback Thursday

Today at Wildfire Today we’re looking six years back, at what we were writing about March 16-22, 2008.

Oklahoma State Trooper burned in grass fire. Trooper Josh Tinsler, 23, was severely burned while checking to see if there was anyone at home in a house that was threatened by a grass fire near Hollis, OK.

Update on study about large fires and greenhouse gases

Brush fire at Monkey Junction

The sweet smell of smoke. That was the headline above an editorial in the Payson Roundup in Arizona. They were “giddy” about the Forest Service reducing fuels and burning piles.

Lawsuit against Mark Rey and the USFS dismissed. A lawsuit that forced the nation’s top forestry official to apologize in a Missoula courtroom was over.

Pattern recognition in today’s wildfire community

Today we have an article from a guest author, Derrick Davis, a Fire Captain with the Kern County Fire Department in southern California.

Pattern recognition in today’s wildfire community

There is no doubt in everyone’s eyes that fires are burning more intensely than before and the fire service is getting more and more complex day by day. But what has changed from the fires of the early 1900’s?  Have our tactics changed? Has fire taken on a new role and become a beast that is hard to understand?  There is no doubt that things are harder now than they were back then, with land management policies, urban interface and many other factors that leave us in bondage when we try and do our jobs.

But one thing that really hasn’t changed is fire. It still burns exactly the same as it did when man first discovered it, right?  Or are we missing something?  What’s different from the firefighters that arrived to fires via horseback with back pack pumps, Pulaskis, shovels and crosscut saws?  Were their tactics truly any different from ours now? Anchor, flank and pinch. If the fire is too hot, back off and if the conditions allow, go after it. So why are people getting hurt and killed?

If we take a look at some of the recent fatality and near-miss fires, what are some common things we see that leads us down a road into trouble?

  • Unburned Fuel between Us and the Fire
  • Lookouts, Communications, Escape Routes, and Safety Zone (LCES) Not in Place (all components of it)
  • Wildland Urban Interface

These are three major things that can eventually lead to game changing outcomes. We already know that we must face and mitigate them. But the reality of it is, are we truly mitigating them or just checking boxes so that we can move forward?  We know there are many other things, that play serious roles in injuries and near-misses on fires, like human factors, inexperience and the nature effect. Let’s face it, our jobs are dangerous, nature is far more powerful than us, but we step out there and combat against it every summer.  Why not try increasing the odds in our favor?

Unburned Fuel between Us and the Fire

It’s no longer a “watch out” situation. It’s a killer, it’s behind every corner and it’s on every rooftop waiting for the right time to pull the trigger or plant the ambush. We need to really re-evaluate (seriously evaluate) every time that we consider being placed in that situation. The way “today’s” fires have the potential to burn and are burning, our time wedge is greatly reduced and we are having a hard time truly estimating and understanding real and true potential of fire spread and intensity.

LCES Not in Place

It’s a pretty simple concept and is the key to safety and going home at night if you understand its true meaning. It’s not a something we can just cover in a briefing so we can move forward with the plan. It is constant and needs to be continually re-evaluated to ensure safety.

Every crew has at least one lookout, but if it’s only one, can that one person truly see everything that’s coming our way?  Two or three of them plus, a set of outside eyes always helps. What’s the phrase? One is none and two is one. So if two is one, then four is really two? The more lookouts, the better, and other people’s eyes and voices are good to confirm that little voice in your head saying “this isn’t feeling so right” when it’s hot and heavy. Remember that using air resources is great. They can see a lot when they focus directly on you, but air should not be your only lookout.

Communications 

Communication is the key to clarity. It’s a must, and not just internally. You need to have multiple sources. Share information with everyone. Let all the necessary people involved know exactly what your intentions are and ask for feedback. It’s not reality unless it’s shared.  If your assignment or intentions are effectively communicated,and understood by everyone, then everyone knows the plan. If there is uncertainty in the plan it draws questions that will lead to plan modification, probably for a safer working environment.

Escape routes 

We must have escape routes and they must be known. They have to be validated so that in this “new normal” fire environment they will be adequate to lead to the bigger picture (safety zones).

Safety zones

What is a good safety zone anymore? Is it the black? And if that’s the case, what is a good black or burned area?  It’s a topic that needs to be revisited over and over again. If it’s not the black then what is it?  Structures? Roads? Vehicles?  Is the safety zone adequate for the fire behavior that is forecast, predicted and being observed?

LCES is vital to our safety and it needs to be properly understood, developed and practiced.

Wildland Urban Interface

It’s unavoidable that people build their houses in the woods. Who wouldn’t want to be in the woods?  We are asked every year to go out there and save those structures from fire. We get target fixated at times during structure defense. LCES goes out the window and we put ourselves out in front of the fire. These are the things that can spell disaster with a capital D. We will continue to do this every year, so we need to do a much better job of recognizing the patterns that lead to disaster.

So how do we mitigate it and make it fighting fire safer?  Pre-planning to ensure the public is doing their part in creating defensible space is key. This firefighting game is a partnership between us and the public. No partnership lasts very long in an 80/20 effort. It needs to be a 50/50 relationship.

Each year about this time we start preparing for this season’s challenges after catching our breath and look back at the adventures of the past summer. Most of us go “wow that was a good one, glad we got out of that one safely”. But why are we still having the “that was close” conversations? Are we failing to recognize the patterns that lead to trouble?  Is our situational awareness not built up enough?  As it’s been said before, we go out each year and go to war with a force that is always much stronger and more powerful than us. Don’t you think we should start stacking the odds in our favor?

Keep your head and senses up and come home safe.
