When it comes to OSHA and their safety standards in regard to compressed air, it boils down to two main topics. OSHA standard 1910.242(b) and 29 CFR-1910.95 (a).

OSHA standard 1910.242(b) – Compressed air shall not be used for cleaning purposes except where reduced to less than 30 psi and then only with effective chip guarding and personal protective equipment.

For a logical reader, it might seem that this standard requires the air used for tasks like blowing off equipment or cleaning floors to be limited to a maximum of 30 psig. However, this interpretation isn’t entirely accurate. When the standard mentions reducing air pressure to below 30 psig, it specifically refers to the static pressure measured when the air nozzle is blocked against an object, such as a person’s body. The “dynamic” pressure, which is the speed of the air as it flows from the nozzle, can be much higher, provided that the static pressure “Dead end Pressure” remains under 30 psi when the nozzle is obstructed. This is why it’s crucial for employers to educate their workers about the dangers of compressed air and the significance of not modifying air nozzles.

Our Air Nozzles and Jets video shows a great depiction of how this can be achieved with our engineered design of nozzles. The recessed holes and the fact that there are multiple passages for the air to exit are easy to see on the nozzle. Products like the Super Air Knife may not be so easy to see, but the way the air knife cap overlaps prevents the Super Air Knife from being dead-ended in the event an operator comes into contact with the discharged air.

OSHA standard 29 CFR-1910.95 (a) – Occupational noise exposure.

The Occupational Noise Exposure regulation (OSHA’s 29 CFR 1910.95) mandates that employees who are exposed to an average noise level of 85dBA TWA (time-weighted average) must be included in a Hearing Conservation Program (HCP). Employers are obligated to ensure that these employees receive hearing conservation training throughout their employment. This training should commence with an initial orientation and be reinforced annually. Section 1910.95(a) of the standard lays the groundwork for a hearing conservation program aimed at safeguarding workers from the detrimental effects of noise exposure in the workplace. Let’s take a brief look at the key aspects of implementing a hearing conservation strategy, including the “what,” “who,” “how,” and “when.”

The first step in understanding and addressing any sound level issues is to measure the sound. The easy-to-use Digital Sound Meter, model 9104 shown below, allows for accurate testing of noise levels throughout the facility.  Noisy areas can be quickly identified, leading to review, design and implementation of the engineering controls.

Some of the worst offenders for noise violations are compressed air applications.  A prime example would be inefficient blow offs used for cooling, drying, or cleaning.  Open pipe, copper tube or drilled pipe are a few of the common culprits.  Not only do they consume excessive amounts of compressed air, they can produce noise levels above 100 dBA.

EXAIR manufactures a wide variety of engineered products that utilize compressed air and deliver it in a controlled manner.  This allows for the most efficient use of compressed air and keeps the sound levels much lower than homemade methods.  A Super Air Knife can replace a drilled pipe, reducing sound by as much as 20 dBA, while using 50-70% less compressed air.  An engineered Super Air Nozzle can replace an open pipe or copper tube and reduce sound levels down to 74 dBA, and even down to 58 dBA for the smallest available nozzles.

The Occupational Safety and Health Act was signed by Richard Nixon in 1970. Under the United Sates Department of Labor, shortly thereafter; OSHA, or the Occupational Safety and Health Administration was born. OSHA is a large regulatory agency tasked to assure safe and healthy working environments by setting and enforcing standards as well as to provide training, outreach and assistance. Although some people’s first response is to cringe at the word OSHA, they have been instrumental in dramatically reducing injury rates and injury costs without negative effects on employees or companies.

Sure we can all cringe by looking up OSHA horror stories on YouTube. And many of us have a story about that one company that was fined 10’s of thousands of dollars for x, y, or z violations… But in reality, OSHA are not the bad guys. They are not looking for fines, in fact they generally give warnings and timelines to fix possible issues, prior to an incident. The fines typically are generated when companies fail to comply. Yes, I know there are always exceptions, but exceptions are not the rule. We hear and hold on to the radical stories, and the day to day, mundane stories fall to the wayside. Regardless of how we feel, we all must comply.

When it comes to EXAIR products, there are two OSHA standards that we must adhere to. One is related to “sound” and one is related to “dead end pressure“.

First let’s look at the dead end pressure. OSHA Safety requirement 29 CFR 1910.242 (b) discusses the possibilities for air embolisms when more than 30 psi is “dead ended” into your skin. EXAIR products have pathways for air to exhaust so that they cannot be “dead ended”. Each product has a way for the air to exhaust to avoid danger. Here are a couple of examples:

Take note that when being used properly (no horseplay) the airflow will have some path to escape and cannot be blocked. They are designed so that air will escape prior to any danger.

Next we will take a look at OSHA requirement 29 CFR-1910.95 (a). This regulation deals with occupational noise exposure. Measuring sound in decibels (dBA) the magic number is 90. Anything under 90 dBA has no limitations on how long you can be exposed to it. For a reference 60 dBA is about the sound level of a normal conversation, or an air conditioner. 70 dBA is about the noise of a washing machine, 80-85 is like city traffic. Then we start getting loud like a motorcycle around 95, shouting or barking is about 110, and standing near a siren is about 120dBA.

As mentioned, 90 dBA or less is our target to avoid needing alternative solutions such as noise barriers or PPE. Nearly all EXAIR products are compliant at or under 90 dBA. The few exceptions are with some of our high force / extensive reach products such as our High Force Air Nozzles.

Please reach out at anytime if you have any questions, or want to discuss EXAIR and OSHA compliance, or any EXAIR questions at all.
