I have seen over the years where OSHA inspectors has visited manufacturing plants for violations. One of the more common areas that they review are compressed air guns because many of them are very dangerous for Dead-End pressure and noise levels. All of EXAIR Safety Air Guns are OSHA compliant. But there is an additional OSHA guideline 1910.242(b) that deals with Chip guarding and shields for cleaning purposes. With these types of applications, EXAIR offers Chip Shields; either as an option with our Safety Air Guns; or as Chip Shields only, or as a Chip Shield kit. In this video, I will go over the Chip Shield Kits that will add a chip shield to your existing EXAIR Safety Air Gun.
EXAIR has many options when considering Air Nozzles, Air Jets and Safety Air Guns. When considering the safety in using these tools one should consider the extra protection that EXAIR Safety Shields offer. Let’s look at the options and sizes of our Chip Shields.
EXAIR Chip Shields are durable polycarbonate shields that can be used with or without extension pipes. The Chip Shield, as the name suggests, protects the operator from flying debris such as metal chips, shavings and liquid coolants. The use of Chip Shields help meet the requirements of OSHA 1910.242(b) for safe use of compressed air.
If you are ordering a new Safety Air Gun from EXAIR and need a Chip Shield you simply place a “-CS” after the Safety gun model number, For example if you order Model 1210 VariBlast Compact Safety Air Gun (SAG) and want a Chip Shield you would order Model 1210-CS and EXAIR will automatically know the size of the shield and will ship the Safety Air Gun and properly sized Shield. If you would like the same gun with a 12″ extension you would order as such; 1210-12-CS and you will receive the Model 1210 VariBlast SAG with a 12″ Aluminum extension and Chip Shield.
If you have a SAG with an extension pipe and want to add or replace a Chip Shield then we must consider the extension pipe and nozzle NPT. All of the Chip Shields are the same size with the exception of the center diameter and the rubber grommet which will accommodate the NPT size of the Air Nozzle and extension. Here is a list of the replacement shields:
If you have a SAG and do not have an extension pipe or shield we have Chip Shield Kits that will allow you to retrofit your existing gun:
One important note is that SAG’s that are equipped with a Stay Set Hose will not allow for the Chip Shield to be installed. Choosing the correct Chip Shield or Retrofit Kit can be tricky but EXAIR Application Engineers are always ready to help.

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.
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.
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.
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.
