NIOSH Hierarchy of Controls

Last year I hosted a Webinar about the NIOSH Hierarchy of Controls and compressed air safety! You can watch that here on our website!

The hierarchy of controls is a strategy that originates from NIOSH (National Institute for Occupational Safety and Health). NIOSH is the federal agency responsible for conducting research and making recommendations for the prevention of work-related injury and illness. This hierarchy is their recommendation for increasing safety for personnel by taking specific steps and how each step increases safety moving from bottom to top of the pyramid. In this blog I will explain the main elements of the HIERARCHY OF CONTROLS and illustrate how to reach the highest level of control with important compressed air safety standards.

The least effective methods are Administrative Controls and Personal Protective Equipment (PPE). Administrative Controls involve making changes to the way people perform the work and promoting safe practices through training. The training could be related to correct operating procedures, keeping the workplace clean, emergency response to incidents, and personal hygiene practices, such as proper hand washing after handling hazardous materials. PPE is the least effective method because the personnel themselves make the choice to wear them or not wear them in any particular situation. They can be trained on the risks of not using PPE equipment (ear plugs, gloves, respirators, etc.) but we all know it does not always get used. PPE can also become damaged, may be uncomfortable and not used, or used incorrectly.

In the middle range of effectiveness is Engineering Controls. These controls are implemented by design changes to the equipment or process to reduce or eliminate the hazard. Good engineering controls can be very effective in protecting people regardless of the the actions and behaviors of the workers. While higher in initial cost than Administrative controls or PPE, typically operating costs are lower, and a cost saving may be realized in the long run.

The final two, Elimination and Substitution are the most effective but can be the most difficult to integrate into an existing process. If the process is still in the design phase, it may be easier and less expensive to eliminate or substitute the hazard. Elimination of the hazard would be the ultimate and most effective method, either by removing the hazard altogether, or changing the work process so the hazard is no longer part of the process.

EXAIR can help your company follow the Hierarchy of Controls, and eliminate, or substitute the hazards of compressed air use with relative ease.

Engineers can eliminate loud and unsafe pressure nozzles with designs that utilize quiet and intelligent compressed air products such as Air NozzlesAir Knives and Air Amplifiers. Also, unsafe existing products such as air guns, can be substituted with EXAIR engineered solutions that meet the OSHA standards 29 CFR 1910.242(b) and 29 CFR 1910.95(a).

Elimination and Substitution are the most effective methods and should be used whenever possible to reduce or eliminate the hazard and keep people safe in the workplace. EXAIR products can be easily substituted for existing, unsafe compressed air products in many cases. And to avoid the hazard altogether, remember EXAIR when designing products  or processes which require compressed air use for cooling, cleaning, ejection, and more.

EXAIR and the Hierarchy of Controls

The CDC (Center for Disease Control) published a useful guide called “Hierarchy of Controls” that details (5) different types of control methods for exposure to occupational hazards while showing the relative effectiveness of each method.

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.

Minimize Exposure to Hazards Using the Hierarchy of Controls
