Communication & Connection Is Critical

I’ve heard it a thousand times… Communication is the key to success. No matter what avenue of industry, work, or even personal life you are in, this statement rings true. At home, communication between my wife and I, as well as our network of friends is always the easiest thing to forego and not want to spend time on. Once this easy path is chosen the work kicks in because one side of the team doesn’t know what the other side of the team is doing.  Most of the time this works for us, when it doesn’t I quickly realize it would have been a better solution to discuss everything rather than assume or just make a vague attempt at what I think we need to do.

My Rucking Community

As for the network of friends, one of the best things I have learned is, we are not alone… Chances are, if you enjoy doing something or talking about certain topics, even if you are struggling, there is someone, you probably even pass them every day and don’t know. Heck, I even found a group of people that like to get outside of their comfort zones and exhaust themselves physically and mentally through rucking. The fact is, my network of friends is like my council on tough decisions or even daily life recaps, as humans we need other people and interaction is in our being.

At work, this need for communication is just as important. During times like we are currently experiencing thanks to the pandemic, we may be seeing a worst-case scenario when it comes to communicating since we have split into shifts and moved to remote work.

We have blogged before about our response as a company, we have successfully been ahead of the curve on response and how we handled our staffing as well as social-distancing before these “rules” were put out. The largest hurdle for my team was the separation and not being able to easily discuss together due to separating into two shifts. Sharing applications, or problems customers may be experiencing with each other is one of our strong suits. To be able to collaboratively use our experiences to build the best solutions or see improvements was cut in half.

So how have we been able to keep helping customers the same as before when we are divided among two shifts? In case you can’t guess, it is an abundance of communication. We use every tool available to us every single day to effectively discuss what is going on between shifts as well as seamlessly transition notes so a customer who may need contact with both shifts isn’t re-explaining themselves in the afternoon.  Is this easy? No, in fact, we haven’t performed flawlessly this entire time yet we have always kept one focus at the forefront.

We do not want our customers to experience anything different or have any additional hurdles to getting the product they need to maximize their compressed air operation.  In fact, if you have noticed a change I would love to discuss it with you personally. You see, we can’t improve without evaluating the methods, just like the 6 Steps to Compressed Air Optimization, you have to know where you are starting, then fix the leaks.

Teamwork, Leadership, Problem Solving, and History

A few weeks ago I participated in a series of three events that spanned the course of three days.  Each of these events was through a company called GORUCK which manufactures American made gear and conducts endurance events led by Special Forces Cadre that use some of the training methods they have experienced throughout their career in the armed forces. GORUCK also works alongside service projects that help to better and empower veterans as well as their communities. I believe this tag from their page says it best. “So, yes we build gear. Yes, we lead events, build teams, and strengthen communities. But only because if we didn’t, we’d have to find some other way to change the world, one day at a time.” (GORUCK,2020)

 

The events that weekend were to commemorate and tell the story of a battle from Vietnam, specifically the battles for A Shau Valley.  This is where the battle that became known as Hamburger Hill took place.  The valley was an unforgiving place that came with many disadvantages to try and overtake. For example, the elevation goes from 2,000 feet above sea level in the valley to 5,000 ft and anywhere in between thanks to the surrounding mountain ridges.

The valley is also a triple canopy jungle making air support and recon extremely difficult.  This valley was a supply chain during the war and there is still turmoil as to whether the battles were necessary as there were many lives lost and several other options that would have achieved a similar supply chain disruption.  In the end, there were 17 Americans involved in a battle with a constantly changing number of support forces.  100% of the soldiers became casualties, 5 paid the ultimate sacrifice during the battle and there were 2 Congressional Medals of Honor given due to actions during the battle for Hamburger Hill.

Taking roll call and getting the lay of the land for the event.

To learn all of this we started out Friday evening at 2100 hr. in a park here in Cincinnati, on a basketball court.  There were 23 of us total participating in the event as well as Cadre Steve our leader and then a great friend of mine who shadowed and photographed a great portion of the events. After some administration, we did a quick warmup where we quickly learned what it meant to be in sync and to move as a team.  When doing physical exercises, in the dark, with 23 people from all walks of life and varying physical ability it can get interesting. With a team leader assigned by the Cadre, we made around a 1-mile movement as a group carrying with us an American Flag, GORUCK flag, six empty sandbags, and a team weight that weighed in at 25 lbs.

The movement was to a public sand volleyball court where the sandbags quickly went from empty to filled.  Thus adding around 650 lbs of extra weight to the team.  Each movement, from the point we stepped off to filling the bags became a task as we had to stay within a certain distance of each other, everyone wanted to go different speeds and the urban terrain was an added obstacle. Adding in the weight and suddenly the team will quickly realize how important communication as well as cooperative work and supporting one another is.

We then moved to a small secluded area where the Cadre had done some excellent recon to locate a downed communication device that needed relocation. This was a downed telephone pole that we are estimating weighed in at well over 300 lbs and was around 20′ long.  6 people were assigned from the team to carry that and continued our movement to another park within the city limits that had no easy way to reach other than up and over several of the hills our great city offers.  Around 5 miles later and 5 hours later we reached our destination to get some more history on the events that took place during the war.

Along the way, our tactics for the weight continued to vary and we eventually placed 9 people tripping over each other on the heavy communication device, then an additional six on the sandbags, two people on flags, one on the team weight, and the rest just falling in line. By the time we got to the park, everyone on the team had become exhausted, some believed they were carrying more of the load than others, people carrying sandbags would want to not carry weight and have to go under the log then back to a sandbag all because communications were breaking down and the team was beginning to fray at the seams.

At some point it is human nature to look outside rather than inside and begin to focus on what others aren’t doing rather than what you can personally do in order to improve the situation of everyone. The rhythm that the team had been keeping broke down with mental and physical fatigue.  Once we had received some more knowledge on the battles the Cadre asked how we were doing and what could be done better. We gave the team leader at each of these sessions three items they did well and three items to improve on then they are removed from their position and another is placed before the next movement.  This also helps those that were leaders to understand their importance when placed in a support role.

At this stop, we were able to pay out through exercises leaving the communications pole at a safe location and have a better understanding of how to better move as a team and be congruent even in the middle of the night.  We were able to move faster and get to the last stopping point for more education then off to where we started everything at to finish out the event.  From this point on we had constant communication, we were working fluidly as a team and everyone from the front to the back of the pack was in the know of what our goal was, our time, and what was needed to get there.

During these events, every single person gets to fight their own minds and questions whether or not they are being an asset to the team or being a liability.  It is when you are feeling weak, have pain, see others not struggling, or just get tired that this simple question can become devastating.  That’s when everyone has to be willing to communicate and expose their weakness to their team in order for their team to support and help them overcome these internal hurdles.  Not everyone gets there and not everyone can overcome.  The team as a whole will grow closer and become far more effective if the members all experience this.

Experiencing this throughout the course of the night and seeing the kinds of opportunities that the team here at EXAIR has made possible for me to grow goes hand in hand.  When someone here has not experienced an application, or we are weak within a certain area of knowledge or ability, the rest of the team will support, strengthen and ensure everyone makes it through.  This is one reason that communication will always be one of the most important traits I can find in a team member.  It is also one reason EXAIR continues to progress and continue forward even through trying times.

We communicate from the front all the way to the back of the building fluently and concisely.  When something doesn’t happen then we know there is a problem and rather than focusing on blame or what went wrong the teams here all focus on the solution and then we can debrief once the issue is resolved.  This leads to on-time and shipping accuracy percentages that continue to improve over the past decade.  We place our team’s focus on being able to take care of our customers, give them a safe and efficient way to utilize compressed air and be easy to do business with throughout the entire process.

If you would like to discuss any compressed air application you may have or if you would like to discuss an interaction that you have had with us and share anything good or bad, please feel free to contact me directly.

Torque Values and Tapered Threads – Do They Go Together?

IMG_20200202_155004_377.jpg

Over the past few weeks, I have been working on various cars in the garage with some good friends. We generally get together and help each other out to make the jobs go easier as well as help each other learn more about keeping our family’s vehicles safe and even helping out some others that don’t have the means to work on their own vehicles. Throughout these repairs, we always end up in some type of discussion over something fairly technical. Sometimes it is the proper installation of a part such as take the bolts to snug, back them out, then torque to half the total torque value, back off again, then finally tighten to the complete torque.

We also share different ways of doing the jobs, such as how to lessen the amount of hot oil you are about to pour all over your hand, or how to get that rusted bolt out without a torch and without breaking it. One discussion that comes up quite frequently is torque specs and then the torque spec for a tapered thread.

In case you were not aware, the NPT or BSPT (male) inlets on EXAIR products are both a tapered thread. Tapered threads are generally used on pipe fittings under pressure to seal better and provide a secure engagement. When comparing this to a standard bolt, or straight thread, one is generally accustomed to receiving a torque spec on just how tight to get the fitting or threaded product. For example, the 1/4-20 bolts used in our Super Air Knives are torqued to 7.5 ft-lbs. in order to properly seal the cap, shim, and body together. These are straight threads and thus a torque spec is often driven by the material, size, and thread of the bolt. Torque on tapered threads such as NPT or BSPT fittings is not as easy to find, and not really reliable.

For tapered threads, the engagement of the thread is not always at the same point due to differing tolerances on thread dimensions. These differences create different points of thread engagement with the corresponding thread it is tightening into. For these scenarios, the torque specification is not always best suited as a numeric value. If you search hard enough you can find a table like the one shown below, but again, not the best value to use when installing a tapered thread.

Size in-lbs N-m
1/16″ 5 0.57
1/8″ 7 0.79
1/4″ 16 1.81
3/8″ 23 2.6
1/2″ 30 3.39
3/4″ 54 6.1
1″ 78 8.81

I personally would not use a straight numeric torque when tightening something with stainless steel thread into a brass fitting, or other dissimilar materials together. For this scenario, I would recommend using something like the table below. The TPFT value is, turns past finger tight. This means you would snug the super air nozzle, vortex tube, or other fittings by hand to finger tight. Then using a wrench or two if needed, turn the fitting to the correct number of revolutions for the given thread size. By utilizing this method and the correct amount of thread sealant, see John Ball’s video blog below, you can ensure there will not be a concern on whether or not the joint will leak and also if the fitting is tight enough.

NPT Size TPFT
1/8″ 2-3
1/4″ 2-3
3/8″ 2-3
1/2″ 2-3
3/4″ 2-3
1″ 1.5-2.5

Sound: What Is It … More Importantly, Weighted Scales of Frequencies

We’ve blogged about sound and what exactly it is before, see the link. Understanding that sound is vibration traveling through the air which it is utilizing as an elastic medium.  Well, rather than me continue to write this out, I found a great video to share that is written in song to better recap how sound is created.

Now that we have that recap and understand better what sound is let’s dig a little deeper to better understand why some sounds may appear louder to a person when they may not appear different on a sound scale that is shown by something like a Digital Sound Level Meter.

Loudness is how a person perceives sound and this is correlated to the sound pressure of the frequency of the sound in question.  The loudness is broken into three different weighing scales that are internationally standardized. Each of these scales, A, C, and Z apply a weight to different frequency levels.

  1. The most commonly observed scale here in the USA is the A scale. A is the OSHA selected scale for industrial environments and discriminates against low frequencies greatly.
  2. Z is the zero weighting scale to keep all frequencies equal, this scale was introduced in 2003 as the international standard.
  3. C scale does not attenuate these lower frequencies as they are carrying the ability to cause vibrations within structures or buildings and carry their own set of risks.

To further the explanation on the A-weighted scale, the range of frequencies correlates to the common human hearing spectrum which is 20 Hz to 20kHz. This is the range of frequencies that are most harmful to a person’s hearing and thus were adopted by OSHA. The OSHA standard, 29 CFR 191.95(a), that corresponds to noise level exposure permissible can be read about here on our blog as well.

When using a handy tool such as the Digital Sound Level Meter to measure sound levels you will select whether to use the dBA or dBC scale.  This is the decibel reading according to the scale selected. Again, for here in the USA you would want to focus your measurements on the dBA scale. It is suggested to use this tool at a 3′ distance or at the known distance an operator’s ears would be from the noise generation point.

Many of EXAIR’s engineered compressed air products have the ability to decrease sound levels in your plant. If you would like to discuss how to best reduce sound levels being produced within your facility, please contact us.
