  1. Anti-Vibration 101

    When it comes to working in at-height, industry, and construction there is no shortage of dangers. From the risk of falling, heat stress, and cold stress, to dropped tools and deadly gasses, the job site is a minefield of potential hazards. One lesser-known (or at least less frequently talked about) are the dangers of vibrations. This week our Gear Experts® are going to discuss the dangers of vibrations and how the use of Anti-Vibration Gloves can help protect you.

    Bad Vibrations


     

    When the Beach Boys wrote Good Vibrations, they definitely weren’t talking about the kind created by power tools. Using power tools is common on the job site and hard to avoid. Power tools are great – they make extremely difficult tasks easier and save valuable time by making quick work of tasks that would take a lot longer by hand. But, the battery or plug powered devices are pumping out a lot of power and in turn, create a lot of vibrations when in use. Overexposure to those bad vibrations can lead to Hand-Arm Vibration Syndrome (HAVS).

    Hand-Arm Vibration Syndrome (HAVS)


     

    HAVS is diagnosed in three main components.

    Peripheral Neuropathy of the Hands

    This component can cause a loss of dexterity, tingling, and numbness.

    Secondary Raynaud’s

    This component is sometimes referred to as vibration white finger (VWF) and has been described the BC Medical Journal as the most dramatic manifestation of HAVS. Secondary Raynaud’s produces intermittent whitening of the fingers. It typically starts at the tips of the fingers and will travel up your fingers as the disease progresses. You may also experience tingling, pricking, chilling, burning, or a numbing sensation.

    Musculoskeletal Issues

    This is the broadest and least defined of the three HAVS components. Symptoms of musculoskeletal issues include weakness, pain of the hands, wrists, forearms, and elbows, and discomfort.

    Preventing HAVS


     

    HAVS is a serious condition and has been around for decades, but preventative measures can be taken to reduce the effects of vibrations on your hands and arms. Anti-Vibration Gloves have been specifically designed to help prevent the vibrations made from power tools and heavy machinery from making it to your body. But, as with all equipment, knowing the right ones to use is important.

    ANSI S2.73 // ISO 10819


     

    The ANSI S2.73 standard for anti-vibration gloves outlines testing requirements and certifies that the gloves meet or exceed the requirements.

    This standard requires that the gloves meet the following specifications:

    • Must have a full finger design;
    • Must reduce “medium range frequencies” (also referred to as TM) by at least 10% compared to a bare hand;
    • Must reduce “high range frequencies” (also referred to as TH) by at least 40% compared to a bare hand;
    • Must have padding no more than 8mm thick in the palm;
    • Must have at least 50% more padding in the fingers and thumb; and
    • Must not have any break between the palm pad base and fingertips.

  2. 3Z RF Vision Antenna Aligner: Small Cell Mounting

    3Z Small Cell Mounting

    With the 5G rollout in full swing accurate antenna alignment is going to be more important than ever. This week, our Gear Experts® are going to cover the importance of accurately aligning 5G small cell antennas to maximize high-band mmW frequencies and Massive MIMO beamforming antenna performance.

    5G Challenges


     

    5G is a massive leap in cellular technology that will bring near gigabit mobile speeds. It will open up new opportunities for a range of industries from consumer to public health and beyond. But, as with any leap in technology, there are roadblocks that have to be overcome. 5G brings some new challenges that aren’t as prevalent with typical LTE antennas on a tower or monopole.

    Coverage vs Speed


     

    In dense city landscapes, the deployment of 5G will be carried on the backs of small cell antennas that are mounted on buildings, light posts, or any structure that can be used to support an antenna and position it in the direction it needs to be. The reason for this is because of coverage distance.

    Small cell antennas have an extremely powerful signal strength – and they need to in order to transmit 5G. But, as a trade-off for power, the distance they can cover is severely diminished. That means these antennas will need to be positioned closer to the ground.

    Line of Sight


     

    Carriers are using 5G New Radio modeling software to develop their network and rollout plans. But, this software isn’t perfect when it comes to identifying nearfield RF obstacles that could render the antenna useless. That’s where the RF Vision Antenna Aligner from 3Z comes into play. It features a line-of-sight target camera that can help installers both identify and record potential antenna obstructions when performing on-site surveys. Once you’ve achieved a comprehensive antenna alignment with a line-of-sight survey a report is automatically generated of the site for sharing with the carrier.

    Small Cell


     

    The RF Vision is a versatile aligner and fits most antenna types. It features GNSS dual frequency technology to deliver accurate alignment readings – even in high-density urban areas. But, with that being said, aligning small cell antennas still isn’t a walk in the park. Small cell antennas are typically housed in a cylindrical canister which conceals up to 3 directional antennas.

    Alignment can be easier with the use of the small cell reference plate for the strap clamp that comes with the RF Vision. In fact, the small cell reference plate is so simple to use that you simply attach it and line up the tool with the correct antenna. Let’s go ahead and break that down, too.

    Small Cell Reference Installation and Use


     

    The first step when using the small cell reference plate is to install the rubber bumpers to protect the small cell housing. Next, you want to mount the reference plate on the bottom of the strap clamp pointing in the same direction as the rubber bumpers. Please note that you will need to flip the mounting plate for the alignment tool so that it is pointing in the opposite direction of the bumpers and reference plate.

    Once the tool, mounting clamp, and reference plate are securely attached, locate the reference arrow on the bottom of the small cell antenna. That arrow tells you which direction each antenna is facing within the canister. Line the reference plate up with the desired antenna and strap the mounting bracket down tightly so it can’t be moved. Now, you're properly lined up with the antenna and you can proceed with aligning the antenna.

  3. Product Spotlight: 3M SecureFit Safety Helmet

    Protecting your skull is an important part of job site safety. After all, without your head – it’s kind of hard to do anything. This week our Gear Experts® are going to break down the all-new 3M SecureFit X5000 Series ANSI Safety Helmet.

    The Features


     

    Let’s start with the basics of this helmet. Like most standard helmets it features suspension and adjustment options. But 3M has taken these basic features a step further to create a quality helmet that breaks the status quo.

    Suspension

    This helmet features 3M Pressure Diffusion technology in the suspension to increase both comfort and security. In fact, the Pressure Diffusion reduces the force on your forehead by up to 20% when compared to older styles of 3M helmet suspension. The suspension also has been designed to sit lower on the head to further reduce the pressure and increase both comfort and security.

    Adjustments

    What good is a helmet that has comfortable suspension if the helmet doesn’t fit on your head you ask? Well, with 15 different adjustment settings that allow for a range of different height and front-to-back settings, you won’t have to worry about that anymore. Plus, the smooth, turning ratchet suspension system makes the headband adjustments quick and easy.

    Additional Features

    This helmet doesn’t just stop at basic features like suspension and adjustment options. It also includes accessory slots and clips integrated into the helmet that are compatible with a wide variety of 3M accessories. And, it includes a UVicator sensor that is installed on the helmet. The UVicator sensor changes color from red to white over time as it is exposed to UV (ultraviolet) light. Once the color has changed to white it indicates that that the helmet should be retired due to UV exposure.

    Design


     

    You’ll notice as soon as you look at the helmet that it doesn’t look like a traditional safety helmet. That’s because the design is inspired by modern climbing helmets. Who said you can’t be safe while looking cool? And, the brimless design ensures that you have a better awareness of hazards.

    Standards


     

    Now we get to the most important part – standards. After all, you need to know if this helmet is something that you can use on a specific job site. All 3M SecureFit X5000 Series helmets meet ANSI Z89.1-2014 and are Type 1 helmets. We covered helmet standards in more detail in our Safety Helmets 101 blog post. We also have a free Safety Helmets 101 poster that you can download from our Knowledge Base.

    Options


     

    This helmet comes in a wide variety of options. First, you can choose if you want standard or reflective. Then you can choose whether you want a vented or non-vented helmet. The last thing you can choose is color. This helmet is available in a total of 8 colors.

    For more information about the 3M SecureFit X5000 Series ANSI Safety Helmet you can view the product here or click here to contact one of our Gear Experts®.

  4. Product Spotlight: PPG Keeler & Long Anodic Self-Priming Cold Galv

    PPG is a household name. Primarily known for their paint and coatings, PPG isn’t a name that comes to mind for most people when they are thinking about cold galv. But, through their Keeler and Long brand, PPG offers a full line of Self-Priming Cold Galvanizing Compound. This week, our Gear Experts® are going to break down Keeler & Long Anodic Self-Priming Cold Galvanizing Compound.

    Cold Galv 101


     

    Cold galvanizing compound (cold galv for short) is a single component zinc coating that is used to protect bare steel from rust and corrosion. It is applied like paint, but it’s not paint. It actually gives the same protection as hot dipped galvanizing and it also makes painting a tower easier. Cold galvanizing compound acts as an active coupling to the bare steel parent metal to form an electrolytic bond. In the presence of an electrolyte (aka moisture) the zinc dust in the cold galv will sacrifice itself to protect the steel.

    For a more complete breakdown on cold galv, surface prep, application methods, and more click here to check out our full Cold Galv 101 blog post.

    Keeler & Long Anodic Self-Priming Cold Galvanizing Compound


     

    The Keeler & Long Anodic Self-Priming Cold Galvanizing Compound is a rust inhibitive coating designed for corrosion protection in a single coat. Keeler & Long Cold Galv is self-priming in many applications and will dry when applied in temperatures down to 35 degrees Fahrenheit as long as the temperatures are expected to rise over the following months. The Keeler & Long Cold Galv Compound is usable for coating weathered galvanized or previously painted surfaces of transmission or communication towers, poles, substation structures, chain link fencing, buildings, and bridges.
