The value of critical thinking could probably never be understated in our industry.

I’ve found that many of the sharpest minds and best leaders I’ve encountered in fire protection are avid readers and relentless learners. Reading regularly is an incredibly valuable tool to broaden our perspective and grow our own limits. 

This week I’m taking a step aside from the technical content a putting up a summer reading list for books I’ve found interesting and helpful for professionals in our arena.

#1 Talking to Strangers
Accomplished author Malcolm Gladwell offers an extremely timely perspective of our natural tendency to overestimate our ability to judge others and underestimate our own ability to be understood. Published just in Fall 2019 this book explores major storylines of the last few years and breaks down the misunderstandings we carry when talking to strangers. 
​
This is a powerful and timely read, especially after the events of the past couple months. | Link

#2 The Future is Faster Than You Think
If you’ve followed some of the prior book summaries I’ve written you know that the advancements we have coming our way in the near future is something I take great interest in. This book is a continuation of my favorite book of all time (next), by Peter Diamandis. 

Every innovation we’ve achieved has been from a mixing of ideas that are at the cusp of the technology at any given time. We have witnessed more technological advancement in the last one hundred years than our entire history before it. 

While we naturally tend to think the present will continue into the future (without major innovation) for the next decades, our history is saying the opposite; the time gap between major innovation has shortened (think major disruptions like internet and cell phones). Due to “convergence” of a wide variety of innovations in transport, medicine, AI, and a host of other developments, these time gaps are getting shorter. If our history has shown us anything, its that the pace of change is increasing and the near future will see major advancements that will reshape how we view the world. | Link

#3 Abundance: The Future is Better Than You Think
I’ve written on this one before, but I continue to circle back to it and never finish the book without a sense of hope for the direction our world is heading.

​If you follow the nightly news its easy to see that the world is shattered and on the verge of complete collapse… except that’s a microview.

Stepping back and looking at trends across history, its clear that we’re in store for a better, cleaner healthier future that is backed by data. A phenomenal read. | Link

#4 Design is a Job
This is a surprisingly brash and straightforward book of guidance on how to market, sell and support a design-related business.

​While the author is in the programming and graphic design industry, so much of the discussion in this book applies directly to the architectural/engineering space.

​A very interesting and refreshing read about the nuances of working in a design-related field. | Link

#5 Thirst: A Story of Redemption, Compassion, and a Mission to Bring Clean Water to the World
This is the first time I’ll mention it, but it won’t be the last. The long-term vision for going starting this website and going independent is to try and make the world a little better each day. Water doesn’t just fight fires, it’s the single most important need we have as humans. This book takes a very personal transformative story of a nightclub promoter turned major nonprofit co-founder. The more interesting and encouraging part of the story is about the positive impact that providing clean water to the developing world does. The long-term MeyerFire vision is pointed directly at the most fundamental need we have globally and we’re saving towards some exciting goals on this front. More to come, but as for the book it’s an impact read. | Link

Those are five of my most impactful reads recently. What have you read that you'd recommend? Comment here.

I hope you are having a great week.

This week is a 2020 update to a popular post from 2016 with a free PDF cheatsheet. It's usefully for novice designers or experienced inspectors, with clear code references and purposes of each of the components that go into a floor control assembly serving a fire sprinkler system.​

​

Last week I introduced a Remote Area Analyzer that evaluates remote area size and shape. 

This week could possibly be the biggest and best expansion of any tool created thus far. I'm thrilled to present a beta version of our Sprinkler Estimator tool. 

With a few default adjustments, you can quickly get a remote area's pressure and flow demand, remote area shape, and have a live schematic of the calculation that updates without a need for "re-running" the calculation. 

For a long time now I've wanted a tool where I could quickly estimate pipe sizes and a remote area's demands before I started laying out the system so that I could be as efficient in my design workflow as possible. What typically takes me 30 minutes to a couple hours can now be gathered in less than 30 seconds.

Another fun application? Want to see what effect k-factors have on your calculation? What about long sprigs? Or what about pipe schedule changes? Wet versus dry systems? What about a consistent branch size versus changing pipe diameters? With this tool you can adjust parameters with just a click and see the live impact it has on your calculation.

I'm really not trying to hard sell this one, I've just had my morning coffee and I'm thrilled to have you give it a try. It's been something I've thought about and developed piece by piece for a couple years now. 

The best way to experience it is with the downloadable version of the Toolkit. You can get a free 30-day trial of that here, or download the latest full version here. The downloadable version has a split-screen that shows the live preview and live calculated results while also allowing you to adjust parameters... no scrolling required.

Click here to give it a try on our cloud version, and shoot me an email at joe@meyerfire.com if you have any feedback or suggestions.

Thanks and I hope you have a great week!

When I initially set up a hydraulic calculation for a tree-style sprinkler system, there are a few key points I have to consider. All of these points today and the tool are specifically for tree systems (not gridded).

First, we need to determine what the remote area actually is. In NFPA 13, for instance, there are multiple adjustments (quick-response sprinklers, dry systems, sloped systems, high-temperature, etc.). Even if we start with a 1,500 sqft remote area, it could look a lot different after multiple adjustments.

Second, we need to determine the minimum length of the remote area along a branch line. This is a relatively straightforward at 1.2 x √ (remote area size), but it's still another hand-calculation that needs to take place.

We then round up to determine the sprinklers along the first branch line, then expand by branch lines to figure out how many sprinklers are actually in a calculation.

The tool I'm introducing today (which is also now available on the Toolkit) is a schematic-level remote area analyzer that will apply multiple adjustments and quickly estimate the important parameters associated with a remote area.

With only a few quick inputs, you'll see an initial remote area laid out with a live schematic of your situation. Click either of the images below to give it a try:

If you already have the toolkit, you can download this and three other recently added tools in today's Toolkit update here. If you're interested in giving this tool a try, check it out here. I'll have it up without any login credentials for a couple months.

In time, I'm looking forward to expanding this tool to have some powerful estimating abilities. 

Any suggestions, tips or feedback? Post a comment or shoot me an email at joe@meyerfire.com. 

A Hurting World at Large
Just like I don't ask hollywood to be my moral compass, you don't come here for my my personal opinions. I get it. That said there has been a tremendous amount of unrest here locally, nationally, and worldwide this past week.

I think there's a major feeling that our collective perspective has to improve. I want to do better and be part of a better future for everyone. I want you to know that whoever you are and wherever you are, I very much care about you and your well being. You have tremendous value. Hope you and yours are safe, healthy, and doing well.

Thanks & I hope you have a great week.

Did you know there are over 1,500 variations of sprinkler models which are actively on the market today?

Around three years ago we began development on one of the largest research projects we've ever undertaken - organization of all the fire sprinklers available on the market today. It took several hundreds of hours to finely comb through all the k-factors, pressure listings, spacing distances, model numbers, responses, and links to websites and product data.

​The Comprehensive Fire Sprinkler Database
In late 2018, we finally released it - a comprehensive Fire Sprinkler Database. With it you can search by SIN, k-factor, type, spacing distances.... most any parameter you need to in order to find the sprinkler that's the best fit for your design.

​The introductory video to it is here (forgive the terrible voice narrator... it was me): https://www.youtube.com/watch?v=DsLPg4GKaCU

Updates from This Week
Just this week we've updated the database to include recent releases for new sprinkler models from Tyco, Viking, and Reliable, including new window sprinklers, concealed sprinkler options, MRI sprinklers, institutional sprinklers, and corridor sprinklers.

Use It Today
If you haven't checked it out - here's an opportunity to do so. I've opened it up for everyone just for the next couple weeks. Just go to this link - www.meyerfire.com/sprinklerdatabase - and login using info@meyerfire.com as the username and sprinklerdatabase as the password if you're not already a Toolkit subscriber.

What's Next?
For those in the inspection department - it's been asked how we can take this to the next level.

Can we get obsolete and recalled sprinklers into the database as well, so that we can quickly search to find information on recalls? That answer is yes, but I need your help. I'm not regularly involved in inspections, but I know many of you are.

If you have a good understanding of where all the various manufacturers recall information (old and current companies) and how I could best showcase that material, please reach out to me at joe@meyerfire.com. I'd be happy to get some input on how I can tackle this next phase of the database and make it that much more useful for us all.

​Thanks & have a great week!

Another summer on its way, and another year of feedback says that the Fire Protection PE (Principles and Practices of Engineering) Exam ranks as one of the toughest disciplines based on pass rate.

Here are some figures for first-time examinees from the Fall of 2019:

And here's what we saw for repeat examinees:

What's New in 2020?
This is a big year for the Fire Protection PE Exam. The long-awaited transition to computer-based testing has shaken up the exam with plenty of new offerings, new standards, new questions styles, and stirred up the prep-community too.

Exam Updates
I'll start with the exam first - this fall will mark the first Fire Protection PE Exam that's computer-based. They'll be given on a single-day this fall (October 22, 2020) at Pearson-Vue test centers.

The exam is moving from an 8-hour, 80-question, multiple-choice only question style to an 8.5-hour, 85-question, varied question style exam. 

Why the change? The exam will start to feature "alternative item type" questions that have shown to better test knowledge than the multiple-choice style questions. The can consist of multiple-correct answer questions, point and click, sequencing, drag and drop, or fill in the blank style answers.

While there isn't an expectation that all the exam questions will be this style, it'll be introduced for the first time this fall and should become more prevalent in future exams going forward.

New Standards
Gone are the days of lugging 75-pound suitcases full of hardcover books into the exam room. I say definitively say 75-pounds, because that was the limit the airline accepted when I took the exam.

The new exam features ready-access to PDF versions of multiple standards, and a new NCEES supplied reference manual. Here are the changes across the board, by year: 
​

In 2020, we're seeing a total of eleven references for the exam. This now consists of ten different standards, but pulls out the two largest volumes with the SFPE and NFPA Handbooks from the exam. 

While this is opposite of the direction we've been told the exam would take for a long time, it will do a good job of reducing the sheer quantity of content that's referenced by the exam into more practical deliverables.

New 2020 Prep Guide & PE Prep Series
The MeyerFire PE Prep Guide is getting an overhaul, as it does most years, to update to the latest exam standards. This year is taking some extra work and we're still looking to ship out by the end of May. The 2020 Prep Guide incorporates all the standard changes and has some new question styles, too. 

Each year is a bit of a writer's jam between when the exam standards are published and when I get the 2020 PE Prep Guide out for printing. This year has been especially busy and I sincerely appreciate the patience while I get this edition updated so that it's helpful for you, the user. If you've pre-ordered a copy and are dying to get started studying, reach out to me at joe@meyerfire.com and we'll see if I can set you up with materials in the interim. Thanks again for your patience.

The PE Prep Series will start the first week of June. It's our most adaptive and robust series of questions we have - the difficulty is closely monitored to help mirror the actual exam, all of the questions are timed, it's entirely computer-based, and it incorporates the question styles of the exam itself. Learn more about that here.

New PE Roadmap
The prep-space is updating as well. One of the frequent requests I've gotten the past few years is about studying - what should I study? When should I study? Am I on the right track? How do I keep myself accountable?

In the past there's only been a study course or two to help with this.

I'm now proud to say there is another option for those looking to go beyond the PE Prep Guide & online questions, but who might not be a good fit for a full-fledged course. It's the PE Roadmap by Chris Campbell. He's an Adjunct Lecturer at the University of Maryland, a Senior Fire Protection Engineer, the writer at the Building Code Blog, and a great guy.

With the PE Roadmap, he's building on the book and the online questions I've written with his own guidance on when & how to study with study schedules, guidance on study content, and one-on-one personal check-in calls. Check the full offering here: www.buildingcode.blog/pe-roadmap

​Thanks & have a great week!

While couped up in our house I've been binging on creating cheatsheets instead of Netflix. Sorry Tiger King. 

This week I'm debuting an overview of the components for seismic bracing in fire sprinkler systems. Seismic bracing is a nuanced and complex topic, but my hope with this overview cheatsheet is that you'll have a starting point for reviewing all the different requirements that go into seismic bracing.

As always, be sure to check the code, the commentary, and any other information you can find on these topics to make sure your work or your reviews are top notch.

That being said, here's the two-page introductory cheatsheet for seismic bracing in sprinkler systems under NFPA 13. If you find this content helpful, please considering sharing with colleagues and subscribing to resources like this here: www.meyerfire.com/subscribe.
​

​Thanks and have a great rest of your week!

A couple weeks ago I sent a sprinkler obstructions cheatsheet for the options with standard spray sprinklers and ceiling-mounted obstructions where the sprinkler cannot throw over the obstruction.

Thanks to some great suggestions, I've now incorporated some visuals that might help. As always, thanks for the feedback! You can download the updated cheatsheet here:

NFSA Expert of the Day Handbook Coming Summer 2020
One of the major projects I've been working on since last fall is development of the National Fire Sprinkler Association's Expert of the Day Handbook. It is a two-volume hardcover compilation of thousands of informal interpretations by NFSA's Experts, spanning 2004 through 2018. 

The set will be available through NFSA later this summer (likely by July). I'm thrilled to be a part of compiling these in a searchable, organized manner that could very well be the go-to resource for suppression design, inspection & testing outside of the standards themselves. There will be plenty more on this as the book becomes available for sale, but wanted to share a little of the good news on this exciting undertaking. 

Thanks & I hope you have a safe and great rest of your week!​

Earlier this week I read a very basic question on a sprinkler design forum. Some say there are no bad questions. Those hypothetical people may never have been in a Facebook Group.

The question clearly showed the lack of understanding on the part of the person asking the question.

You can imagine what happened next – the keyboard warriors went to battle. They had fun blasting the novice into the internet oblivion.
 

And this happens all the time.
 

It doesn’t have to be Facebook. It happens on Facebook for Businesses (also known as LinkedIn), email forums, Reddit, and other online technical forums.

It is also not limited to the digisphere. A bad question in a conference room or in the field gets chided at best or embarrassingly criticized at worst.
 

Did we all not start somewhere with nothing?


I’m not a second generation Fire Protection Engineer, but my guess is those that are third and fourth generation practitioners don’t come out of the womb spelling escutcheon correctly.

I'm still not 100% convinced I spelled it right just now.

We all started knowing literally nothing. We each are on our own journey learning piece by piece and at different paces that never really ends. The best experts that have spent three decades in the industry are still always trying to improve.
 

Is there harm in asking a dumb question? Yes, but it’s not the embarrassment in the moment or the obvious display of misunderstanding. It’s the discouragement to ask the next question.

When Average Jim (I have to use Average Jim because Average Joe hits a little too close to home for me) actually seeks an answer to a basic question and gets lambasted – you know what he’s not going to do? He’s not going to ask the next five questions that he also needs answers on. 
 

On the very first morning of my very first internship, I asked a bad one. I was maybe 15 minutes into that first day when the site project manager asked me to make copies of a handful of documents. I asked if the staples had to come out before making copies.

Dumb question? Yeah. Do commercial copiers appreciate hard metal through their sensitive little feeder claws? No. And had I ever used a commercial copier before? No.

If I hadn’t asked, would I have been the dufus that destroyed a commercial copier 15 minutes into his first internship? Yeah brah, that would have been moi.
 

I heard so much crap about asking that question, but I was glad I did. I also never had to ask it again.

Eventually my questions got slightly more sophisticated and a little better, but I did start at nothing.

 
I’m not going to change human behavior. I can’t help people act online like they would in a face to face conversation.

What I can do is provide a better avenue for those people who don’t want to be vilified but do need answers to their question.

With nearly a couple decades of internet usage we know now that it isn’t Vegas - what happens on the Internet stays on the Internet. Like forever.

It’s getting more and more difficult to ask a question that isn’t tagged to your name, your company, or your reputation. Your forum question you wrote in 2007 when you didn’t know anything on pre-action systems? Yeah it’s probably still searchable.

Goodness knows I’d rather not have my kids go post-by-post from what I put on Facebook during high school. Same would go for a client seeing questions I would have had early in my career.
 

So what can I do about it now? Create a quality avenue for the question - any question - whether it’s expert-level or at square one - and not tie a personal reputation to it.

If you haven’t checked it out, the Daily Forum is a place for a single, filtered, anonymous question each day. There are experts there from a wide variety of backgrounds and locations that have far more knowledge than I could hope to gain.

Experts from across the globe, from AHJs to Designers to Researches to Installers to Engineers. Last I checked we were approaching nearly 3,000 subscribers just to those questions.
 

If you have a "dumb" question, if you don’t want to ask your boss, if you need an outside opinion, and you don’t want your identity tied to something it? Send us your question here. Also consider bookmarking the page so you can send in that question the next time you're stumped.

The link toward the bottom of this email “Have a fire protection question?” is always there for exactly that same reason.
 
Chances are, if you have an interest or can’t find an answer, someone else is looking for it too. When you ask, we all learn. And that’s exactly what this site is all about. 


Free NFSA Virtual Conference Tomorrow
This year's National Fire Sprinkler Association Business and Leadership Conference went Virtual. The virtual seminars are this week (Thursday the 30th and Friday the 1st). Registration is live, it is FREE, and CEUs will be awarded. Check it out here.

I had the pleasure to talk about the changing digital media opportunities in fire protection with the host of the Fire Sprinkler Podcast, Chris Logan, as part of the virtual conference. I believe we'll air at 2:35 pm Eastern Time on Thursday.
​

A New, Free, Fire Protection App
I've gotten asked a good handful of times - "Will you make an app?"

While I am quintessentially a millennial who disowns being a millennial, I have thought about making an app.

The good news is, there's already one that I was able to help beta test and can now share with you. It's free and was developed by Michael Swahn and the helpful engineers over at Sebench Engineering out of Atlanta. It's now live on both Google Play Store and the Apple App Store. Here's links to get it:

Apple: https://apps.apple.com/us/app/sebench-engineering/id1506207375
Google Play: https://play.google.com/store/apps/details?id=al.pragmatic.sebench.android
 
The app has quick-calculations for Fire Pump Tests, Hydrant Flows, Equivalent K-Factors, Flow/K-Factor/Pressure Calculations, and Friction Loss. Download it today with the links above.

Thanks & I hope you have a safe and great rest of your week.

There are a handful of rules in NFPA 13 covering how sprinkler protection works in and around obstructions. It's for good reason; we don't want objects getting between a growing fire and our best method of suppressing it.

The PDF cheatsheet this week covers options for throwing water below obstructions, where the top of the obstruction is at or above the sprinkler deflector, for standard pendent and upright sprinklers.

If the sprinkler deflector has the ability to throw over the top of an obstruction - different rules apply - which we'll get to in the coming weeks. 

To get your free PDF download, enter your email below and you'll immediately have the PDF sent right to you. If you're already subscribed to the blog, check the Recent Resources section at the very bottom of your latest April email.

​As always, any tips, ideas or feedback feel free to send my way at joe@meyerfire.com. Hope you find this helpful and that you have a great & safe week!
