Minimizing Hazards using the CDC’s Hierarchy of Controls

CDc Hierarchy of Controls

The management and effective control to reducing or eliminating workplace hazards can be frustrating. Controlling the exposure(s) to occupational hazards is the fundamental method of protecting employees. The CDC published a useful guide called “Hierarchy of Controls” detailing 5 types of control methods as a means to implement effective control solutions.

The idea behind this hierarchy is that the control methods at the top of graphic are potentially more effective and protective than those at the bottom. Following this hierarchy normally leads to the implementation of inherently safer systems, where the risk of illness or injury has been substantially reduced.

Elimination and substitution, while most effective at reducing workplace hazards, also tend to be the most difficult to implement in an existing process. If the process is still in a development stage, elimination and substitution of hazards may be inexpensive and simple to implement. For an existing process, major changes in equipment and procedures may be required to eliminate a hazard.

With 23 lbs of hard hitting force, this 1-1/4 NPT Super Air Nozzle is perfect for the most extreme blow off and cleaning jobs.

EXAIR can help your company follow the Hierarchy of Controls, to eliminate or reduce the hazards of compressed air usage. Many EXAIR products, including Super Air Knives and Air Amplifiers are simple to use for the substitution level of the hierarchy. The simplest substitution may be any of the EXAIR Air Nozzles and Jets, which have been designed to meet OSHA standards. All are safe to be supplied with higher pressure compressed air and meet OSHA standards 29 CFR 1910.242(b) and 29 CFR-1910.95(a).

Of course, when designing new systems, keep these products in mind and begin to design safer and more efficient compressed air demand elements of your machines and processes.

This Is A Hold Up

To clarify, right off the bat:

  1. Nobody is getting robbed here.
  2. Nothing is being delayed, especially a shipment from EXAIR. If it’s in the catalog, it ships on time, 99.97% of the time, for 17 years & running. This has nothing to do with this blog; I just never get tired of bragging about that.

Today I wanted to write about installing EXAIR products, but hey, it’s Friday, so I thought I’d start with something that would get your attention. If you’re still reading, I guess it worked.

We talk to users…and potential users…all the time about how to install an Air Knife, Air Nozzle, Vortex Tube, etc. And the answer is…it depends. But, it’s almost always quick and easy.

Consider the EXAIR Super Air Knife. There are a few ways to hold one in place:
*There are 1/4″-20 tapped holes, every 2″ along the bottom. These can be used to bolt it to just about anything you want to bolt it to.
*The 1/4″-20 cap screws can also be replaced with fasteners of sufficient length to allow use of a bracket. In fact, this is what we use for…
*The Universal Air Knife Mounting System – it’s a quick and convenient way to support an Air Knife. It’s especially beneficial to precisely position the Super Air Knife for optimum performance.
*Last but not least, Super Air Knives 24″ and longer need to be plumbed to both ends for proper performance. If you hard pipe it in, it’ll be as well supported as the piping.

EXAIR Super Air Knives are easy to install, no matter what the length, or application.

Then there’s our Super Air Nozzles:
*With standard, common NPT threads, these are easy to install anywhere you have an existing air line. You can get NPT adapters for darn near any threaded connection, off the shelf, from a friendly local air compressor or hydraulic/pneumatics shop.
*We’ve got Stay Set Hoses in lengths from 6″ to 36″ – these let you reposition the Air Nozzle at will. It’ll “stay set” until you bend it again.
*Our Swivel Fittings can be used with any of our Super Air Nozzles, as well as our Air Amplifiers, for sturdy, yet easily repositionable, installation.

EXAIR Swivel Fittings or Stay Set Hoses - no better way to optimize your air flow than aiming it where it needs to be!

We’re even committed to making our air preparation accessories easy to install…our Automatic Drain Filter Separators, Oil Removal Filters, and Pressure Regulators (up to 1/2 NPT) can be coupled via a modular block assembly that eliminates a threaded connection between them, and is ideal for close quarters.

That’s not even mentioning the products that are ready to install, right out of the box with a convenient Magnetic Base:
