TACTICAL FIRST AID + BLAST INJURY CARE

Today I received an email from InSights about changes to one of their classes:

InSights Training Center Tactical First Aid Featuring Caring For Blast Related Injuries On August 3, 2013

Bellevue, WA – InSights Training Center announced today that it added Blast Injuries Care to the Tactical First Aid class to be taught by Mike Shertz M.D. on August 3, 2013.

Following recent events we are reminded that we need to be prepared for injuries occurring to yourself and/or others during an active fight situation.  With these factors in mind, InSights Training Center has expanded it’s Tactical First Aid curriculum to now include caring for blast related injuries.

Most penetrating injuries are not immediately life-threatening. However, there are some injuries where death before the arrival of EMS is almost assured if not quickly and effectively managed.

Our 1-day Tactical First Aid class is designed to give you the knowledge and skill to identify and manage those immediately life-threatening injuries, whether they occur to you or another individual, while you are still engaged in the violent attack.

The cost of the Tactical First Aid class is $225. Students may register at http://insightstraining.com/view_course.asp?courseID=11.

The temptation is great

Barb L. and I have arranged to spend some time on the beach next weekend.

After making the arrangements my thoughts soon went to what my profile on Match.com (where I meet Barb) said about the beach:

Long walks on the beach are nice–if we brought the explosives to see how big a crater we can make in the sand and how high the water will shoot up into the air.

In addition to the legal issues involved I left my chemistry set in Idaho.

Still… there are solutions to most of the issues and the temptation is great.

Quote of the day—Tam

We Americans do love our killin’. Lots of dead bodies, one or three at a time, every day… Of course, Europeans like their killing, too, but they tend to do it every twenty years or so, and by the millions. Personally, I prefer the Etsy model to the Wal-Mart model. I mean, when you think about it, our killing is more European… artisinal. To say nothing of the carbon offsets you’d need to buy to run a mass crematorium these days.

Boomerite packaging test

On Saturday Barron and I did a simple test on the Boomerite packaging. It was hypothesized that the heat from heat shrinking the plastic wrap was causing evaporation of the ethylene glycol. We put a thermocouple temperature sensor just inside the cardboard box and applied the heat shrink plastic bag as normal. There was less than 1 degree F rise in temperature.

We applied heat until the plastic melted. The temperature just barely raised. That means it’s not the heat.

There are two remaining hypotheses:

  1. The additional thickness of the shrink wrap caused compression of the Boomerite when we squeezed the same number of boxes into the crates. I’ll have to order some more boxes and heat shrink bags to test this hypothesis.
  2. The slight change in mixing order changed things. Last year when we had exceptional good detonation rates someone, not me, had the bright idea of mixing the potassium chlorate with the secret ingredient before mixing in the ammonium nitrate and ethylene glycol. They told me they were doing it and I had sort of a nagging feeling about there being a reason not to do that but my brain wasn’t working well at the time* and I okayed it. A day or two after the event I figured it out. They were, in essence, making “flash powder”. The EG goes in first to eliminate the dust and static electricity during the mixing process.

It will probably be the middle of June when I go back to Idaho to do the tests.


*Just two weeks before I had served papers for legal separation on my wife of 35+ years. This year I was feeling much better and one guy told me that I looked terrible the year before and that this year I “looked ten years younger”. He also asked, “Is the new woman you are with (Barb L.) just as smart as you? I confirmed his suspicion that she is a smart cookie.

Random thought of the day

Ry stopped by my office this afternoon and shared this bit of knowledge with me:

When you are shooting into a fire a red dot sight is totally worthless.

It’s obvious in hindsight but neither he nor I thought of it ahead of time.

Boomershoot 2013

By most accounts Boomershoot 2013 was good. Two people even came up to me afterward and told me, “This was the best one ever.”

From and staff/organizational standpoint that was certainly true. Everything occurred on time or perhaps only a few minutes late. The targets were produced in record time. The targets were deployed in record time. The clean up on Sunday night was completed in record time. The Saturday dinner and raffle went exceptionally smooth as well.

I give credit to all the staff who showed up early or on time, knew what to do, and worked long hours.

There were some disappointments from the participant side.

The targets for the high intensity events had a very low detonation rate. My guess is that fewer than half detonated. The air should have been filled with so much water vapor that people would have difficulty seeing the targets.

IMG_4447

The detonation rate for the main event was better but still below what we have come to expect.

The low detonation rate was at least 90% responsible for the disappointing fireball this year.

We have more tests to do but the best hypothesis so far is that the heat guns used to do the shrink wrapping of the targets overheated the ethylene glycol in the Boomerite and evaporated a significant portion of it. Our tests were done in the winter and a lot of our target production was done when it was very warm in the shipping container.

The weather wasn’t bad. It could have been better though. On Sunday the winds were high enough that some people reported 10+ feet of windage was required for .223 calibers at the tree line 380 yards away. It’s crazy to expect to get hits on a 4” square target when you put on that much windage.

IMG_4606

On the good side, at noon we moved about 150 or 200 7” targets from the distant hillside to the tree line. The original targets at the tree line were 3” and 4” square. The addition of 7” square targets was very popular with the shooters and there was a great deal of excitement as the targets detonated in rapid succession. The difference between hitting 2 MOA and 1 MOA targets is huge.

As usual there were interesting people and equipment at Boomershoot:

Most of the staff left about 5:45 PM. Daughter Kim and Jacob left sometime after 6:00 PM. I puttered around Mecca putting things away, taking down the tent, and packing stuff into my vehicle for the return trip to the Seattle area the next day. I left via the tree line at the Boomershoot site and spread the remaining coals from the trash fires to cool. I left at almost exactly 8:00 PM. It was still light out which was a first. There have been times, like last year, when I did not leave until after 11:00 PM.

Boomershoot 2013 final prep

I arrived at the Boomershoot site Saturday April 20th. This was almost a week before the event started.

I was coming from the Seattle area and drove via Colfax, Lewiston, and Kendrick. I was pleased to see the hills were greening up and took a few pictures. This one was as I was a few miles out from Kendrick:

WP_20130420_005

What I didn’t tell anyone except my brothers, who helped me load the flooring material on the top of my vehicle, was that I was going to put down a new floor at Boomershoot Mecca before anyone else arrived. Here I have the rolls on top of the Escape just after I arrived on site:

WP_20130420_008_Web

I actually gave some clues to the staff that something was up in this post.

I had great fun seeing the surprise on people’s face when they noticed the new awesome floor. And even more fun when Barb L. didn’t notice. This was even though on our previous visit to Mecca just three weeks earlier we had talked a great deal about doing something different with the floor. We had just about settled on tile. But with all the stuff in the shipping container it was going to “have” to wait until after Boomershoot this year. I found some roll flooring that I was able to install, by myself, in about one day’s worth of work.

Barb had spent many minutes inside Mecca and I even asked her if she saw anything different. She couldn’t figure it out. I finally asked her about the floor and she went a little crazy about it (“I could totally get my freak on about it! I could mop it!”). She really likes to have clean floors and with the previous floor it just wasn’t practical.

After my tent blew down the hill in the Sunday evening windstorm I put a 50 pound bag of ammonium nitrate on each end of the tent to keep it a little more “grounded” for the rest of my stay:

WP_20130422_001

Wednesday I almost always have to myself but at about noon both Scott and Antitango reported they were about to arrive. Scott, as always, arrived first and I had him do some more work preparing a parking area near Mecca for the staff.

I ended up not getting some of the things I had planned on doing done. But we got 500 hillside stakes in the ground Wednesday afternoon! We also had the shooting position stakes and signs laid out and ready for Thursday morning.

Thursday morning Barb and Max L. were there along with Antitango and his gang.

The rubber bands were put on the hillside stakes (or did we get that done Wednesday? I’m not sure.) The fiberglass stakes for the caution tape to keep people from parking in the shooting area were put in place, the shooting positions marked, and the garbage cans distributed by about 10:00 AM.

We were WAY ahead of schedule so we did a quick initial run of targets and learned some lessons. My biggest lesson was to not let the staff run off and try it by themselves. I was getting the Wi-Fi and AT&T microcell up while the staff went off to make a few targets.

Barb L. came back looking for me and said, with a very concerned look on her face, “We need you.” I arrived back at Mecca to the sound of multiple alarms screaming, the air filters off or on the lowest settings, the air filled with dust, and people doing things differently from what I had planned. The alarms were low voltage alarms because they were trying to run everything on the batteries. Batteries that I had already determined were nearly dead. I turned off the lights which was enough load drop to get the alarms silenced, turned all the air filters on high, and started up the generator. I then went inside to talk about my vision of production versus what was actually happening.

My plan also had some problems and after a short run we shut down the line, cleaned up, and went to Orofino for lunch and the Utah CCW class put on by Antitango.

The next morning I rearranged things to correct for the problems discovered the day before. This is what the interior of Mecca looked like on Friday morning before we started target production “for real”:

IMG_4341

And here is the production line in action about 11:30 AM:

WP_20130426_002

And at about 10:30 Saturday morning:

WP_20130427_002

The guy with the smile is Rolf—just so you know what you are dealing with when you read his posts here.

Notice that most of the crates and cardboard boxes are gone. We produced about 1600 targets in less than two days.

We had a lot of staff producing targets. So many that I didn’t have jobs for everyone. This was actually a good thing because part of the time it was very hot in the container and people needed to get out to cool off. We had the staff to swap out and rest while keeping the line up and running.

Here is a picture of the parking area at Mecca Saturday morning:

IMG_4347

Which of the vehicles is not like the others?

Out of band from the target production at Mecca was Ry and Ben (with a little enabling help from me) working on the fireball target at the shooting line. This should give you a clue about the effort involved:

WP_20130427_006

Sunday morning I was on site by about 5:30 to prepare for the rest of the staff that I asked to arrive at 7:00. Here is a picture of the shooting line I took at about 6:30:

WP_20130428_001

The targets were all mounted on the stakes nearly an hour earlier than scheduled thanks to lots of staff and a different target delivery plan. And this included putting in the tree-line stakes Sunday morning instead of Saturday evening as planned.

Ry and Ben assembled the fireball target as the rest of us put the 1000 targets on stakes on the hillside and at the tree-line.

Here is the completed fireball target:

Maybe by this weekend I’ll write up my thoughts on the event itself.

The short version is that some things went exceptionally well. Others were a disappointment.

Boomershoot charity raffle

I just had my bank send the Boomershoot 2013 raffle proceeds to Soldier’s Angels. This included some private cash donations given to me before and after the Boomershoot dinner and raffle.

I received $150 from G. before dinner, then $200 from D., and $40 from someone else (sorry it was quick and I didn’t catch his name) after dinner.

Here is what my bank says about the payment they are making on behalf of Boomershoot:

Boomershoot status

The weather is looking pretty good this year.

Details are here.

The short version is:

  • Friday: Partly cloudy. High of 68F. Winds from the WSW at 5 to 10 mph.
  • Saturday: Mostly cloudy in the morning, then overcast. High of 63F. Winds from the SSW at 5 to 15 mph shifting to the West in the afternoon.
  • Sunday: Partly cloudy in the morning, then clear. High of 54F. Winds from the WSW at 5 to 15 mph.

So far I have been concentrating on getting Boomershoot Mecca ready for target production. Staff will start showing up for a full day of work tomorrow and I want everything to be ready for them. It’s essentially ready now. Just a few odds and ends still to do.

The portable toilets were delivered yesterday. Brother Gary brought the ATV and trailer over yesterday as well.

I had some exciting times when my tent blew away on Sunday night just before I was going to take a nap about 6:00 PM:

WP_20130421_003

A heavy suitcase prevented it from ending up several miles away in the lake. I had heavy rock on the stakes on four corners but it worked its way loose somehow.

There was no way I was going to get it staked down in that wind so I just took the suitcase out and rolled it on down the hill and put it in the shipping container:

WP_20130421_005

My Verizon phone does not have nearly as good a reception at Boomershoot Mecca as my various friends have reported. Ry ordered a Verizon “Network Extender” (a femtocell) for me which is supposed to arrive today.

My AT&T microcell wasn’t working either. I had to reactivate it and got it working on Sunday.

That was the worst of things so far.

I’ve rearranged Mecca some:

WP_20130420_010

I moved the 3350 pounds of ammonium nitrate twice (“vitamin I” is my friend) before I was happy with things.

I did detonation tests on round targets Barb L. and I had built and stored over two weeks ago. Typically targets go dead in as little as a week during the summer. I figured that if even a small percentage detonated it should be considered a pass. In the first batch only 20% detonated. The others got solid hits but just popped open. I switched to hollow points and 80% of the rest detonated. It didn’t seem to matter if the boxes had the shrink wrap plastic on them or not. That is good to know. There is no need for that time consuming step.

Bottom line is that everything is looking good for a great Boomershoot 2013.

Tab clearing

I have a bunch of open tabs in my browser and I only have a few minutes before I’m leaving for 10 days to put on Boomershoot. I’ll have some time to make a few blog posts but I want to clear these up before I go.

It’s rare but sometimes they really do say the incredibly stupid things that we accuse them of:

Rep. Jackson Lee: ‘Don’t Condemn the Gangbangers’ – We Need Gun Legislation

Jackson Lee took the House floor on April 9 to argue in favor of increased gun control legislation, “Don’t condemn the gangbangers, they’ve got guns that are trafficked — that are not enforced, that are straw purchased and they come into places even that have strong gun laws.”

“Why? Because we don’t have sensible gun legislation.”

Jackson Lee continued by saying that current gun laws need to be enforced,  “I’m going to agree with my friends on the other side of the isle. Our Republican friends, let’s enforce the gun laws that we have – – who would run away from that. That’s a sensible proposition. Put a resolution on the floor of the House – – let’s enforce gun laws that we have.”

Yes. She said that. Blame the gun not the criminals.

Yes. She said that. Put a resolution on the floor to enforce existing laws.

Her babblings should qualify her for dementia medicine trials.


I could only see four out of the ten weapons being in the category “you won’t believe are legal”. And then only if you don’t understand the 2nd Amendment. They had to be desperate for content:

10 Weapons You Won’t Believe Are Legal

  1. Flame Thrower
  2. Miniguns
  3. Katana
  4. Cannon
  5. Crossbow
  6. Grenade Launchers
  7. Nunchucks
  8. Umbrella Sword
  9. Speargun
  10. Chain Whip

There has to be more to this than what I have had time to dig into.

Judge: lawsuits can proceed against theater owner in Colorado massacre

A federal judge refused on Wednesday to dismiss wrongful death and personal injury claims brought against a movie theater chain on behalf of victims of last summer’s mass shooting at a suburban Denver screening of the Batman film “The Dark Knight Rises.”

U.S. District Judge R. Brooke Jackson ruled that Cinemark
USA, owner of the theater where 12 people were shot
dead, could potentially be found liable for damages under a
Colorado law that holds landowners responsible for activities on their property.

What? The best I could come up with for a plausible grounds for claiming the theater was responsible was if the plaintiffs believed they were disarmed and unable to protect themselves. And I think that is only about 10% chance of being the case.


Yes. Some people blamed the 2nd Amendment for the Boston bombing:


I once had a boss suggest that I was making so much money at time and a half on weekends that I shouldn’t fly back to Idaho to visit my family. I should just hire a hooker to give me blow jobs under the desk while I continued to write code. I laughed and went home for the weekend.

It turns out there might actually be a market for that sort of service:

Silicon Valley’s other entrepreneurs: Sex workers

In a quiet cafe outside San Francisco, “Josephine” — a local prostitute — arranges a collection of t-shirts across the table. They’re emblazoned with phrases like “Winter is Coming” and “Geeks Make Better Lovers.” She wears them in her online ads to catch the eye of the area’s well-off engineers and programmers.

“I’m trying to communicate to them that I understand a little bit what it’s like to be techy, nerdy, geeky,” she says. There’s another thing Josephine and her clients have in common: Like many of the techies she caters to, Josephine views herself as an entrepreneur.

Boston explosives

I’m setting aside the tears that come from looking at the pictures and reading the articles and just channeling “Spock” as best I can on something I know a little bit about.

The first thing I noticed from watching the video and then from the still photo I found at the Los Angles Times is that this looks like a crude homemade bomb.

BostonBombViaLaTimes

Here is a cropped version from the Boston Globe YouTube video:

BostonBombViaBostonGlobeVideo

This is a full two seconds later from that same video:

BostonBombViaBostonGlobeVideoPlus2Sec

See all that flame? And it looks as if there is still fuel burning in the cloud two seconds after the explosion.

I’m almost certain that no commercial or military explosive produces that much flame. Something like that would be totally banned in the mining industry.

That may mean there was a great excess of fuel in the explosive composition. Boomerite has an excess of oxygen which makes for easier detonation. Maximum power comes from a balance of oxygen and fuel. Some explosives are naturally oxygen or fuel rich. For example TNT is fuel rich. During WW II they would add ammonium nitrate which is (under the proper conditions) an explosive that is oxygen rich. The excess oxygen in the AN increased the power of the detonation by consuming the excess fuel of the TNT.

With that much flame persisting that long after the explosion occurred means huge amounts of power was wasted in light and relatively slowly expanding gases. This was not a military grade explosive. Getting the most bang for the least weight is worth the cost of getting the oxygen balance right.

This means it’s a homemade explosive.

Another possibility is that it wasn’t really a detonation at all but rather a deflagration. For example gun powders typically do not detonate. They “just” burn very rapidly. The flash you see at the muzzle of your gun at night (and sometimes even in bright sunlight) is composed mostly of burning particles of gunpowder. Confine the powder in a strong closed container, such as a pipe, and you get an explosion when the container bursts.

From the sound of the explosion and the speed of the blast product development I’m leaning toward a deflagration.

Mr. Completely sent me an email asking if I could “rule either in or out that readily available reloading powder could have been used”. My answer to that question is that I think it is definitely possible.

Update April 16, 6:20 AM: At least one source says:

…the devices used gunpowder as the explosive and were packed with ball bearings and other shrapnel to maximise injuries.

Update April 16, 1:25 PM: Rick Boatwright has an excellent analysis which points to black powder being the explosive.

Boomershoot 2013 shirts

I’ve created the Boomershoot 2013 Cafepress store.

The image (via Barron Barnett, see also his post) on the products is:

Cafepress

You don’t have to be a participant to buy from the store. And there is still time to enter the event if you do want to participate.

We used 14 pounds of explosives and 13 gallons of gasoline for the fireball in the image above.

Fireball2012Configuration

I got a really good deal on 150 gallons of fuel this year. Ry was a little evasive in his answers but I’m pretty sure he promised not to use it all up this year. You should attend to find out what he has planned. Nomex clothing is optional.

Quote of the day—Mine Safety and Health Administration

Explosives; magazines.

[Shall be]

(4) Reasonably bullet resistant.

(9) Posted with suitable danger signs so located that a bullet passing through the face of a sign will not strike the magazine.

Mine Safety and Health Administration
Title 30 CFR § 77.1301
[Why do people shoot at signs? I just don’t get it. I know that they do because I have seen a lot of shot-up road signs.

And shooting at an explosives magazine is well beyond shooting at the yellow 35 MPH caution sign for going around the curve ahead. It’s nominating yourself for a Darwin award. You would think that seeing a sign that that even hints at “EXTREME DANGER! EXPLOSIVES!” would be enough to give Cletus a clue to keep the muzzle pointed in some other direction. But no. We have to have a government regulation to put the sign in a location such that it has a proper backstop between it and the nearby magazine.

At times one has to wonder about the viability of the human race or speculate that perhaps we discovered fire 100,000 years too soon.—Joe]

The rest of the story

Remember last January when I helped out a new author with some gun and explosives stuff for her story?

Here is the rest of the story.

I haven’t had time to read it all but I’m hooked and making good progress.

Boomershoot 2013 conditions

Things are looking good for Boomershoot 2013. Some years 16 inches of snow on the shooting line two weeks before the event. And we have even had snow on the hillside where the targets are for the actual event.

This year the local farmers were actually in the field for a few days last week before it started raining. Assuming it doesn’t continue like it was this weekend when Barb L. and I did some work at Boomershoot Mecca there should be good ground conditions and lots of green scenery.

Here is what it looked like today:

IMG_4224Corrected2013
The target area is still wet but it will dry out quickly with warm weather.

IMG_4218Corrected2013
The field around Boomershoot Mecca is green and in a few weeks will be very pretty.
IMG_4239Corrected2013
The fog lifting up out of Clearwater Valley looked really neat. The power lines are from Dworshak dam.

Boomershoot daffodils

Most people attend Boomershoot for the chance to shoot at explosives. Some come for the daffodils.

IMG_4226Cropped2013
IMG_4229Cropped2013
IMG_4231Cropped2013

These daffodils were planted by my grandmother and her sisters when they lived on the property where the shooting line is. The daffodils survived even though the land was farmed and they have to compete with the grass for moisture and nutrients.

Each year I think, “This year I’ll move them out of the field and onto the front edge of the shooting berm where they will be out of the field. They will do better without fireballs wilting them.” I think this year will be the year it actually happens. Barb L. saw them for the first time yesterday and she instantly agreed it was a great idea and she has experience with flower bulbs. She plans to help me with the project.

I think that within a year or two we can completely cover the front edge of the berm. I think it will be awesome.
