Chip Shields, OSHA, And You

Safety is a key part of our culture at EXAIR Corporation.  We have regularly scheduled, all-hands required, safety training on a number of topics.  Our Order Entry team can likely tell you as much about our lockout/tagout procedures as our Machinists can.  Nobody even thinks about entering The Shop without safety glasses, and it’s not just because of the signs.

We pay attention to these…
…so we don’t ever have to use this.

OSHA 1910.242(b) states that “Compressed air shall not be used for cleaning purposes except where reduced to less than 30 p.s.i. and then only with effective chip guarding and personal protective equipment. (emphasis mine)  All EXAIR Intelligent Compressed Air Products are engineered to meet the requirements of the first part (30psi outlet pressure to prevent dead ending…we’ve written about that numerous times, including here, here, and here) and we can also provide pre-installed devices to satisfy the second part:  the EXAIR Chip Shield.

Any EXAIR VariBlast or Heavy Duty Safety Air Gun can come fitted with a Chip Shield, and any Soft Grip Safety Air Gun, except for those with Stay Set Hoses, can as well.  Safety Air Guns with Back Blow Nozzles automatically come with a Chip Shield. The principle is simple: a clear polycarbonate (so you can still see what you’re doing) round disc slips over a short (or long if you want) pipe extension between the gun & the nozzle.  It’s fitted with a rubber grommet so you can position it to where it’s most effective – sometimes that might be closer to the part being blown off; sometimes it may be back a little closer to the operator.

EXAIR Safety Air Guns are available, from stock, with Chip Shields.

If you already have an air gun that’s doing the job, you can easily add an EXAIR Chip Shield to it.  They’re made to fit a wide range of extension diameters, and can even come with the extension if you need it.  We also stock a number of adapter fittings; if you know what threads your air gun has (or if you can send us some photos) we can quickly & easily spec those out for you.

Convenient and inexpensive “thumb guns” with cross drilled nozzles (left) are compliant with the first part of OSHA 1910.242(b). Fitting one with an EXAIR Chip Shield (center) makes it compliant with the second part. A Model 1102 Mini Super Air Nozzle (right) makes it quiet & efficient.
We can provide a Chip Shield for most any device with a threaded fitting. I couldn’t find a way to re-use the non-OSHA-compliant nozzle that came with this gun (thank goodness.)
Another example of a larger air gun fitted with a more powerful cross drill nozzle (left) that can be made totally OSHA compliant with an EXAIR Chip Shield (center.) An EXAIR High Force Super Air Nozzle (right) keeps the power, while reducing noise level and compressed air consumption (right.)

Since 1983, EXAIR Corporation has been manufacturing quiet, safe, and efficient compressed air products for industry (emphasis mine.)  If you have concerns or questions about safety in regard to your compressed air use, call me.

VariBlast®Compact Safety Air Gun

EXAR’s VariBlast® Compact Safety Air Guns are small and lightweight air guns capable of handling the toughest of jobs. With its variable flow trigger being its greatest design feature, it can take on small jobs and even big ones! This means you can get different flow and force out of the same nozzle by just adjusting the amount you pull the trigger.

The VariBlast Safety Air Gun, when outfitted with an EXAIR nozzle is OSHA safe and CE compliant. 

VariBlast Safety Air Gun With Extension and Chip Shield

The VariBlast can also be customized by adding one of our many 1/8 NPT engineered air nozzles, a chip shield and even an extension pipe up to 72″ long.

Safety Air Gun Promotion: Now Through September 30th!

August 1st through September 30th EXAIR is running a promotion that’ll get you a free 1” Flat Super Air Nozzle with the purchase of any promotional VariBlast, Soft Grip, or Heavy Duty Safety Air Gun. Inexpensive air guns are commonly seen through a variety of industrial supply companies. Most consist of poorly made parts or materials that will wear out and break quickly. In addition, their performance is commonly akin to that of an open-ended pipe and can necessitate an extremely high compressed air consumption.

In addition to wasting unnecessary air, they’re also VERY loud. Many of these guns do not adhere to the sound level restrictions set forth by OSHA in 29 CFR 1910.95. All of EXAIR’s Safety Air Guns are available with Chip Shields to protect operators from debris and adhere to dead-end pressure requirements as outlined by OSHA 29 CFR 1910.242(b). It’s much easier to implement safe products upfront than after you’ve had a random inspection by OSHA. As anyone who’s experienced one can attest to, they don’t just fine you once. You’ll get fined for each individual location in your facility where operators are using air guns that don’t adhere to the proper standards.

1699-CS-PRB.png

EXAIR offers (4) different styles of Safety Air Guns with a wide range of different force levels, flows, and accessories. The VariBlast Compact Safety Air Gun is a powerful gun that allows you to adjust the force delivered from the gun depending on the trigger valve pressure. Pull the trigger just a little for a light force, or all the way for maximum force without having to adjust your air pressure. It’s small and compact, but powerful while still light and ergonomic. blog_SGSAG_500x

The Soft Grip Safety Air Gun has a durable cast aluminum body suitable for rugged industrial use. The large trigger makes for easy operation and a convenient hook at the top allows the gun to be easily stored. Chip Shields for worker safety and extensions for hard to reach areas are available up to 72” long.

The Heavy Duty Safety Air Gun also comes with a durable cast aluminum body and incorporates a rugged composite rubber grip. Also with a wide trigger, these guns can be used for hours without fatigue. The Heavy Duty Safety Air Gun is available with Chip Shields and extensions up to 72”.

As part of the promotion, you’ll receive one free Model 1126 1” Flat Super Air Nozzles. Delivering a 1” wide, high velocity airflow, these nozzles utilize EXAIR’s patented shim design to maximize entrained airflow while reducing noise levels. They also offer a great deal of adjustability, shim sets in varying thicknesses are available to allow you to either reduce force and flow, or increase it depending on the application. Don’t wait until after the promotion ends, get your Safety Air Guns on order now so you can take advantage of this great promotion!

Flat Super Air Nozzles by EXAIR: A Wide-Range of Customizable Solutions

EXAIR’s Flat Super Air Nozzles have been blowing away the competition since 2003.

EXAIR’s line of 1” and 2” Flat Super Air Nozzles are rugged, efficient, and ideal for applications that require a wide forceful stream of airflow. The patented design utilizes a special shim to maintain the critical position of the component parts. The result is a laminar, high velocity blast of air with minimum air consumption and sound level.

The Flat Super Air Nozzles are available in a wide range of configurations. With both the 1” and 2” sizes you have the ability to select either Zinc Aluminum alloy or Type 316 Stainless Steel for higher temperature or corrosive applications. They’re also available installed at the end of our Safety Air Guns. The 1” Flat Super Air Nozzles are ideal for our VariBlast Compact Safety Air Gun while the 2” is suitable on either our Soft Grip Safety Air Gun or the Heavy Duty Safety Air Gun.

With extensions ranging from 6”-72” and Chip Shields also available, you have the ability to tailor a blowoff gun to your exact application. Since the design of the nozzle prevents any chance for it to be dead-ended, all configurations will be compliant with OSHA directive 29 CFR 1910.242(b). This means you’re able to operate at pressures in excess of 30 PSIG without risking harm to your operators.

In addition to two different sizes and materials, there’s also a wide range of shims that can be installed. Just like the Super Air Knife, the thickness of the shim installed (in addition to the input compressed air pressure) will dictate the force and flow through the nozzle. For both the 1” and 2” Flat Super Air Nozzles, shim thicknesses are available ranging from .005”-.030”. Thicker shims will increase the force and flow, thinner shims will reduce it while also reducing the air consumption. To allow you to experiment with different flows, we make shim sets available that’ll allow you to test out a few different sizes in order to determine the best solution for your application.

New to EXAIR in 2018, the Model 1144 2” Super Air Scraper is a patent pending nozzle used to remove stuck-on debris from work or machine surfaces. It incorporates a strong corrosion resistant scraper blade to add necessary leverage to allow you to get underneath and scrape away debris. The strong airflow from the 2” Flat Super Air Nozzle then is able to get underneath and blow away the material. The scraper nozzle is great for applications involving the removal of tape from floors, gaskets, adhesive, labels and stickers, grease, paint and sealant. It’s also available on the end of our Soft Grip Safety Air Gun with durable ¾” air extensions in lengths ranging from 6”-72” and Chip Shields. All of these possibilities are available from stock with same day shipments.

EXAIR’s wide-range of solutions allow you to customize the product to your exact specifications. Stop wasting time and money replacing cheap plastic air nozzles, get yourself a nozzle that’s Built to Last by EXAIR!

Airguns, OSHA, And You

Depending on the context, those may be three words you DON’T want to hear in the same sentence. Case in point…a caller I spoke with recently, who works at a large steel forging plant. During a recent inspection, management was surprised (and disappointed) to find out that, unbeknownst to them, some of their operators had modified some of their compressed air blow off devices.

These modifications left them in violation of both OSHA Standard 1910.242(b) (limit on outlet, or dead end pressure) and 1910.95(a) (limits noise level exposure.)  The OSHA inspector left them with an $8,000.00 fine, and a promise to return with an even higher one if the situation wasn’t corrected.

We discussed the ways their current devices were supplied, the conditions they were operating in, what they were used for…and why the operators had modified them.  Sadly, we found the devices were underperforming due to air supply issues – hoses that were too small in diameter and/or too long, with restrictive quick connect fittings.  And some of their modifications (drilling out the discharge) just exacerbated those problems.

Most of their applications were pretty typical – blowing flash, chips, oil, coolant, etc. from processed metal parts.  Typical enough that a couple of EXAIR Safety Air Guns would allow them to determine what they would need, by taking them around to various stations in the plant and trying them out.

My caller ordered a Model 1210 Soft Grip Safety Air Gun with a Zinc Aluminum Super Air Nozzle (our most popular for typical blow off applications,) and a Model 1260 Soft Grip Safety Air Gun with a High Force 1/2 NPT Zinc Aluminum Super Air Nozzle (the most powerful one available on the Soft Grip Safety Air Gun.)

Here’s Model 1210-6-CS, fitted with a Zinc Aluminum Super Air Nozzle on a 6″ Rigid Extension & Chip Shield.  All EXAIR Safety Air Guns are compliant with OSHA Standard 1910.242(b).

I feel pretty good about the chances of publishing a future blog about the success of this application.  If you want to keep up, I encourage to follow the EXAIR blog – there’s a link to the right to provide your email address – for more on this one, other applications, and a wealth of expert writings on how to get the most out of your compressed air system.

As always, if you’d like to discuss a particular compressed air application and/or product selection, give me a call.
