The SCBA revolution

1 comment

Thirty pounds. That’s a well-packed office bag, complete with laptop, paperwork, power supplies, etc. It’s a couple of grocery bags, gathered in a bundle to save a last trip from the car to the kitchen. Most people wouldn’t think twice about carrying thirty pounds of anything more than a few steps from the Metro to the office, or from Best Buy to the car. In truth, it’s not that much weight, for short periods of time. But try carrying it on your back while you run, crawl, crouch, climb, or even just take a bone-jarring step down from an elevated vehicle cab with more weight than your body was built to be spry with. However, regardless of the complaints or the conditions, firefighters do this several times each day; and there’s no shortage of members who will tell you the toll it can take on their bodies. The extended use of the Self-Contained Breathing Apparatus (SCBA) currently utilized by departments all over the world doesn’t seem to lead to friendly outcomes for firefighters’ knees or backs—two problem areas that plague many within the brotherhood, both past and present.

Future generations—perhaps even our own, within the next few years—may soon be forced to worry about something else. Vulcore Industrial, based out of Fort Wayne, IN, has been developing what they call the “Flat Pack.” With this new design, they’re setting themselves up to revolutionize the way firefighters carry their most essential tool: breathing air. Current systems are based around a metal cylinder with a carbon fiber over-wrap; at 7+ inches in diameter, the added bulk on top of already shoulder-widening gear can make confined or entangling spaces almost impossible to navigate. Accordingly, a significant portion of fire academy instruction is related to maneuvering with the SCBA; at times, areas can get so narrow that one must resort to removing a shoulder strap and swinging the system around to the side of the now “thinner” firefighter.

At a diameter of 2.75″ each, the multi-cylinder system provides firefighters with no more bulk than a mostly empty school backpack. The new system—based off of CEO Stan Sanders’s patented design and a material called Hytrel—is molded into the thin bottles and then wrapped with Aramid and carbon fiber. According to the manufacturer’s specifications, the first “808 model” weighs up to 30% less than current systems, putting the prototype at a hair over 20 lbs. The “Cobra” model is advertised as 30% lighter than the 808. Thus, the potential exists for a breathing apparatus with the same amount of air/breathing time; but at 14 lbs, it’s over 50% lighter than what the fire service is using now. Vulcore Industrial was unavailable for comment, although their full set of Frequently Asked Questions is available here.

In 2008, the Department of Homeland Security offered a 15-month, $2.7 million grant to the IAFF for the purposes of equipment research; and although the technology and initial prototypes were born from Vulcore, they just didn’t have the manufacturing power to mass-produce their product. Mine Safety Appliances, more commonly known throughout the fire service as MSA, has been assigned the daunting task of making Vulcore’s dream an assembly-line reality. The grant money will additionally be used for field testing and fulfilling government/NFPA certification requirements. An advisory committee working with the IAFF and International Personal Protection, Inc. has recommended a 45-minute service-rated system for the initial wave, although Vulcore states that they have the ability to produce 30- and 60-minute systems for different applications.

According to the May/June 2010 issue of International Fire Fighter, “Several firefighters from the Washington, D.C. area, conducted rigorous field tests to determine how a new, lighter, and lower-profile system would compare to the traditional SCBA… [the] series of functional tests, including timing, donning and doffing, roof operations, ladder escapes, crawling through tight spaces and fire ground survival skills” appeared to bode well for the system’s future in emergency services. Initial reactions are overwhelmingly positive, due to the light weight and increased maneuverability:

Additionally, videos posted on Vulcore’s own website show how the Flat Pack simplifies many of the entanglement hazards present inside dangerous environments:

The IAFF is expecting commercial production of the Flat Pack within the next year, marking a new introduction to an application that hasn’t changed since the first firefighting breathing apparatus was developed almost forty years ago.

A physics nerd’s take on technical rescue.

With an uneasy creak, the spools began to move.

The chains could be heard pinging as they tightened and eventually held fast—little by little, the heavy wrecker began to lift the mammoth monolith of masonry that lay before us in a jungle of weathered stone and twisted rebar.

Yes, it’s drill time again; however, instead of going down into a trench, we’re going up in the air. E15′s collapse drill focused on shoring up ceilings, breaching concrete, and using our behemoth of a heavy rescue crane/wrecker to elevate the chunks of concrete that are piled haphazardly behind the Training Academy.

I have not yet attended the Collapse Rescue class that is afforded members of my firehouse; however, I have always found the physics principles that are inherent in technical rescue fascinating.

That’s right. I’m a classical physics and engineering mechanics dork at heart. Reading about formulas put together by the Army Corps of Engineers is one thing, but applying them in a real-world situation and seeing the results happen in front of you is entirely another.

Today was certainly no exception to my eager thirst for geeky science stuff; pictures, as always, can be clicked for a larger size.

Our concrete jungle, complete with… all sorts of junk.

The big bad boy wrecker. The boom itself is rated for 60 tons, and each of the two cable spools is rated for 16,400 lbs.

Rigging our strangely-shaped concrete tube of choice.

The Captain looks on…

Success! Yes, this is what I did at work today. I love my job.

Trench drill; or, playing in the mud for fun and profit.

One of the unique things about being assigned to Engine 15 is the occasional need to support Rescue Squad 3 in their technical area of expertise: trench and collapse rescue. We’re expected to know more than the average bear about the various tools and concepts within the scope of these topics, and to be able to assist the squad guys with various aspects of each while on the scene of an actual incident.

Sure enough, I found myself back at the Training Academy on a dreary mid-week morning, slogging through the mud and dragging various lengths of lumber around.

It’s an entirely new set of skills (and a language that goes along with it, to boot) that I have yet to learn. Although from what I saw during this drill, I think it’d be something I would enjoy—hell, I’ve always loved building things, so combine that with some ropes, a bit of math, and a whole boatload of physics? I’d be a happy guy.

(Haha, you’ll have to forgive the weird vignetting on some of the photographs. I’m using a digital camera from 2004—which makes it electronically ancient—and the shutter leaves over the lens get stuck sometimes. I think it’s kinda cool, actually.)

The new Resusci-Annie is more than okay, guys. She’s damn fine.

Q: “Annie, Annie, are you okay?”
A: Hell yes she is.

I present to you: Super Sexy CPR (also coming in June, Super Sexy Abdominal Thrusts! Main link here, slightly NSFW). If they could have made a year-long paramedic course as riveting as the following video, I’m certain I would have entered academia to study this sort of thing instead of being a street-level provider.

Maybe EMS isn’t so bad, after all.

Georgetown University EMS: a story in photos.

1 comment

A little while back, I spent a day with Georgetown University’s EMS system (officially yet whimsically known as “G.E.R.M.S”). I originally contacted their PR director because I was intrigued by the notion of an independent emergency service provider that operates within a city that already has a full-coverage Fire and EMS Department. It’s not a bad little operation; the providers are competent and excited to work, their training regimen goes above and beyond the national minimum standards, and there’s certainly no shortage of undergraduate students eager to join the ranks. As an entirely student-run organization under the umbrella of Campus Safety, they have developed as an excellent resource on campus whose response and subsequent medical care has proved useful to students, faculty, and visitors alike.These frames and accompanying text are what I dug up one rainy afternoon with G.E.R.M.S.

Thank you to the entire G.E.R.M.S administrative and training staff, with a special thank-you to Brendan Maggiore (VP of Operations), without whom this endeavor would never have come together. If anyone would like to see additional pictures from that day, all of them are available in this gallery on Raising Ladders Photography.

Keep up the great work, G.E.R.M.S.!

P.S. – an interesting bit of lore: on a shelf above the staff mailboxes, there is an old frame holding a conundrum of a photograph. It is, quite clearly, a glamour shot of actor Danny Glover. However, upon closer inspection, it says “To Germs, continue your great work. Danny Glover.” The strangest part? Nobody has any idea how it ended up there. Despite the photo’s prominent location for “quite some time now” (i.e. longer than anyone whom I asked remembers), there are no records, memories, or even legends of its origin. One G.E.R.M.S. member took it upon himself to look back more than a decade into the service’s employment records, interviewing and calling prior staffers about the photo—nevertheless, the search proved once again fruitless.

Any ideas?

10am: Area Drills.

“Uh, left on Rhode Island, right on Montana… uh… left on…”

Frustrated, I looked down at my paper. There were lots of street names, copied from the chalkboard—just no descriptions of how to get there, which was the purpose of the whole exercise.

It will come in due time, I suppose. I’ve been trying to learn the area as best I can without formally receiving any maps or running routes; it’s been mostly based off of talking with the wagon driver and the other guys on the back step with me. We’re all supposed to know our first-due area like the backs of our hands, and now that I passed my seventh-month test last tour, I’ll be receiving a list of common addresses to tackle—not to mention major buildings, abnormal addresses, hydrant locations, short streets, and a plethora of other data that we need to know.

I remember when I was sixteen and volunteering as an EMT, I had a map of our first-due area that I had drawn my self, and I used to drive around the area on the weekends to get a feel for it. I may have to do this again; granted, the area I’m supposed to know is much larger now, but I believe the process is the same.

Just add it to the pile of stuff to study; a fellow probationer told me that your eighth-month test is the hardest, because it’s more of those damned questions on top of trying to turn your head into a mapbook.

Either way, it’s just another step. As one of the more senior technicians told me last tour:

“One day, you’re going to be here at night, sleeping. And then the bells are going to go off. And as you wake up, you’ll hear the address… and a map is just going to pop right into your head. You’ll know exactly how to get there… and by the time you fully wake up, you’ll realize that you’re sitting outside of that very house with the parking brake on.”

Note: Similar to “The Sitting Room,” “10am” will be reserved as a header title for anything related to drills and training—the name stems from the fact that by Department rules, every shift is to train on something at 10am each day (with certain exceptions, but the general idea holds true).
