How Does EXAIR Fit Into the NIOSH Hierarchy of Controls?

The Occupational Health and Safety Act of 1970 established the National Institute for Occupational Safety and Health, also known as NIOSH. This organization was founded with the goal of researching worker safety and health, and providing guidelines for employers to create safe and healthy workplace environments. A division of the Centers for Disease Control and Prevention (CDC), NIOSH has been diligently working to ensure that information is accessible to those who want to improve the safety of their operations.

On the NIOSH section of the CDC website, they’ve published a helpful guide for helping you to control and minimize the risk of exposure to hazards in the workplace. This hierarchy of controls provides a framework from most to least effective in terms of the way you manage these hazards and the exposure to your operators. This hierarchy of controls contains (5) levels of actions that can be taken to reduce or remove hazards from the workplace. In order of most to least effective, these controls are:

  1. Elimination
  2. Substitution
  3. Engineering Controls
  4. Administrative Controls
  5. Personal Protective Equipment (PPE)

 The least effective option for mitigating risks may not have been what you originally thought. PPE, or personal protective equipment, is something I’m sure you talk about often with your operators. Would you believe that this is ranked as the least effective method of preventing risks? This is because equipment can become easily damaged, may be uncomfortable and not always used when necessary, or simply used in an improper manner. We’ve all been guilty of doing something that we know we should’ve likely worn some PPE for, just out of convenience. Since it’s so easy to forget or simply not use, it makes PPE the least effective method when it comes to enhancing safety.

Moving up one notch on the scale we have administrative controls. These are also at the lower end of the effectiveness spectrum. These types of controls are centered around making changes to the way personnel works around the equipment. This can be achieved through implementation of training to correct operating procedures, cleanliness of the workplace, personal hygiene practices (proper hand-washing after handling hazardous materials for example). These, again, rely on the operator to listen and act in the way they’re trained.

Engineering controls reside in the middle of the effectiveness range. These are implemented by design changes to the equipment or process that reduces the risk of hazard. These controls can be very effective in protecting people regardless of the actions or behaviors of the operators. They are higher in cost generally than an administrative or PPE control, but can make operating costs lower and allow for a cost savings over the long-term.

Substitution is where EXAIR’s Intelligent Compressed Air Products come into play. By offering engineered solutions that meet or exceed OSHA Standards 29 CFR 1910.242(b) and 29 CFR 1910.95(a), EXAIR’s line of Safety Air Guns, Air Nozzles, and other engineered blowoffs will ensure your operators are not at risk when using our equipment. Anywhere you’re performing some sort of compressed air blowoff process, it’s important to be using equipment designed with safety in mind.

The most effective, but usually the hardest to implement, is elimination. This involves physically removing the hazard from the process. In many cases, a complete elimination is not going to be possible. That’s when you turn to the substitution method and look to EXAIR for a solution.

With years of industry experience under our belt, we’re well-equipped to help you improve safety in your workplace through a variety of off-the-shelf products. Give us a call today and we’ll be happy to discuss how we fit into your facility’s processes!

OSHA Safety Standards for Compressed Air

Safety should always be a serious concern within industrial environments.  Walk through any production facility and you should see all kinds of steps taken to give a safe workplace to the operators, contractors, and other team members.  Whether this is through a sign showing PPE required to enter an area, an emergency exit sign, a safe walkway, or machine guards.  Safety has become a standard that should never be lowered and there is good reason for that.

EXAIR designs all of our products to be safe and they meet or exceed OSHA standards that are directed toward compressed air safety.  The first is to ensure that an operator or maintenance worker will not be injured through air impinging their skin should they come into contact with an EXAIR product.   This OSHA standard is 29 CFR1910.242(b) claiming that all point of use compressed air products must be regulated to have less than 30 psig of dead end pressure.   This directive is critical for worker safety and the way many blowoffs skirt by is to cross drill holes in the end of the blowoff.

Cross drilled holes may satisfy the dead end pressure standard but it does not address OSHA’s next important compressed air standard about noise exposure, OSHA standard 29CFR1910.95(a).  The allowable noise level standard combined with 30 psig dead end pressure will render many home made or retail nozzles near useless because few, if any, meet both standards.  Again, EXAIR has engineered and designed our Super Air Nozzles to permit 80 psig inlet pressure and still meet or exceed both of these OSHA standards so that the work can still be done by the operators while remaining safe and retaining their hearing.

For a better explanation and demonstration of how our nozzles meet these standards please see the video below.

While I use nozzles and cross drilled pipes as examples within this blog these safety features are designed into every product that EXAIR offers.  This is due to the fact that OSHA, NIOSH, and the CDC do not delineate between a blow gun, blow off within a machine, or even a Cabinet Cooler System.  If the device is powered by compressed air then the two key OSHA standard are in effect due to the inherit dangers of compressed air.

I encourage you now to walk through your facility and try to listen or spot compressed air points of use within your facility.  Then, I ask you to call, chat, e-mail, or tweet an Application Engineer here at EXAIR and let us help you determine the most efficient and safest product to get the work done.

EXAIR Nozzle Improves Safety & Worker Comfort

This week’s adventures in using compressed air arrives from an unexpected source: installing handlebar grips on a bicycle. The customer used a compressed air gun with an open tube which is not OSHA safe and is LOUD! (pictured below)

This original nozzle does not comply with OSHA’s dead end pressure standard and is exceptionally loud.

The bicycle shop would slip the nozzle of the air gun under the rubber handlebar grips to expand them to slide onto the frames easily.  The original nozzle of the gun did not have a relief port in the nozzle to prevent pressurization over 30 PSIG as mandated by OSHA instruction STD 01-13-0001. On top of the over-pressurization problem, the gun was incredibly noisy. This noise was the reason for their call. During the course of our phone conversation, we also discussed the safety aspect of their application. If you need more information on OSHA’s regulation regarding compressed air please see my blog “Complying with OSHA’s Compressed Air Standard”.

The bicycle repair shop was relatively quiet, so the noise from the 0.175″ opening of the original safety air gun affected a number of shop employees. Every year more and more studies point to a link between occupational noise and health, well being, and productivity. This repair shop had a relatively low noise level in most working hours, so the noise of the air gun continuously rattling through rafters not only threatened the operators’ hearing but also may have affected them in other ways.  The technician manager of the repair shop had heard complaints from operators and called one of EXAIR’s Application Engineers to find a quieter solution. Our solution was the Precision Safety Air Gun, model 1410SS, was the perfect solution. The 1/4″ Nano Super Air Nozzle is 1/4″ in diameter which was able to easily slip underneath the handlebar grips. The gun would then be triggered which allow air to fill the handlebar grip, which caused it to expand just enough to slip onto the bike frame.

Originally, the air gun produced noise levels of over 90 dB every time the gun was triggered. EXAIR’s 1410SS Precision Safety Air Gun only produced a noise level of 75 dB, which is much more manageable in their shop environment. The gun also features EXAIR Super Air Nozzle design which conserves compressed air and complies with OSHA standard 1910.242(b), which prevents the outlet pressure from exceeding 30 PSIG.
