Compressed Air Safety Fundamentals

Published on by jasonkirbyLeave a comment

Safety in the workplace is of paramount importance, and it is widely recognized that annual safety training is a common practice among organizations. A fundamental message from these training sessions is that safety is a collective responsibility, not limited to a select few. At EXAIR, we prioritize safety in all aspects of our operations. Our product line, particularly our Safety Air Guns, exemplifies this commitment, as they are engineered with safety considerations at the forefront. This emphasis on safety is critical, especially given the potential health hazards associated with the improper use of compressed air.

In the United States, the Occupational Safety and Health Administration (OSHA) is responsible for enforcing regulations that promote safe and healthy working conditions. This agency possesses the power to levy significant fines for any infractions. Among the frequent violations related to compressed air are those concerning air guns and blow-off devices, specifically detailed in 29CFR 1910.242(b), which addresses dead-end pressure and chip shielding, as well as 29CFR 1910.95(a), which pertains to permissible noise exposure levels.

The regulation 29CFR 1910.242(b) addresses the use of hand-held tools, particularly emphasizing that blow-off devices must not operate at pressures exceeding 30 PSIG when there is a risk of compressed air becoming dead-ended. In situations where there is no escape route for the air, it poses a serious risk of penetrating the skin and causing an air embolism. A potential remedy is to drill a hole to create an alternative escape route. However, this solution may introduce additional safety hazards, which will be discussed later. EXAIR’s air nozzles are engineered with fins that facilitate safe air escape, thereby preventing skin blockage. Consequently, users can operate the EXAIR Super Air Nozzles at pressures exceeding 30 PSIG with confidence.

The regulation 29CFR 1910.95(a) specifies the permissible sound levels for safe human exposure, emphasizing that extended exposure to elevated noise can result in irreversible hearing loss. However, the cross-drilled nozzle falls short in this regard, as it generates significant noise due to turbulent airflow, despite being suitable for dead-end pressure applications. In contrast, EXAIR’s nozzles are engineered to incorporate ambient air, resulting in a significantly quieter laminar flow. For example, the Model 1210 Safety Air Gun, equipped with the Model 1100 Nozzle, operates at a sound level of only 74dBA, which is comfortably below the noise exposure threshold for an eight-hour work shift.

Utilizing EXAIR Accessories

Published on by jasonkirbyLeave a comment
Accessories

At EXAIR, we take great pride in our Intelligent Compressed Air Products, which are renowned for their efficiency and minimal maintenance requirements, thanks to their design featuring few or no moving parts. While we often highlight these advantages, we also do not want to overlook the importance of the accompanying accessories that enhance our products’ performance. These accessories play a crucial role in ensuring our compressed air solutions maintain their low maintenance and reduced noise levels, further solidifying their compliance with OSHA safety standards.

Compressed air filters and regulators are among the most essential accessories we offer, and we highly recommend their use with all our products, as well as with other brands. The Filter Separator effectively eliminates water, dirt, and rust from your compressed air system, while the 5-micron filter element prevents contaminants from clogging or damaging connected equipment. For more precise and additional filtration, an Oil Removal Filter should be installed downstream of the Filter Separator; it utilizes a 0.03-micron element to remove oil and solid particles. Our Pressure Regulators allow you to set the desired operating pressure, and we advise maintaining the minimum pressure necessary for optimal performance. This not only conserves air but also fine-tunes the efficiency of EXAIR products in various applications.

Good engineering practice calls for point of use filtration and moisture removal, such as that provided by EXAIR Filter Separators.
The Thermostat’s leads (left) are spliced into the Solenoid Valve’s ‘hot’ lead (bottom right), which essentially acts as the automatic temperature controlled ‘on/off’ switch for the Cabinet Cooler System. NEMA 4/4X versions include mounting hardware (top right).

We offer specialized accessories designed to enhance the performance of some of our products. For instance, our Line Vacs are complemented by the Line Vac Hose, while our Cabinet Coolers can be paired with Thermostats and Solenoid Valves. Additionally, we recommend Mufflers for optimal use with our Vortex Tubes. When it comes to our Air Knives, we provide several excellent options. The Universal Air Knife Mounting System offers a straightforward and dependable solution for mounting. For applications requiring longer knives or independent control of airflow sections, our Coupling Bracket Kits are ideal. Lastly, our Air Knife Plumbing Kits simplify the plumbing process for Air Knives exceeding 24 inches in length.

For those looking to connect Intelligent Compressed Air Products, we offer a range of compressed air hoses and fittings designed to enhance the convenience of installation. Coiled Hoses are an excellent match for our Safety Air Guns, providing greater mobility during operation. Additionally, our Compressed Air Hoses are frequently utilized with our Industrial Housekeeping products, ensuring that both the drum and dolly have the necessary reach for effective use.

Industrial Safety: Compressed Air

Published on by John BallLeave a comment

At EXAIR, we have a statement that says, “Safety is everyone’s responsibility.”  EXAIR builds its name around manufacturing safe and protective compressed air products.  In the United States, we have an organization called the Occupational Safety and Health Administration (OSHA) that enforces governmental directives for safe and healthy working environments.  They do training, outreach programs, and educational assistance for manufacturing plants to reduce injuries and fatalities.  They can also enforce these directives with heavy fines for violations.  With compressed air systems, the two most common violations are 29CFR 1910.242(b) for dead-end pressure/chip shielding and 29CFR 1910.95(a) for maximum allowable noise exposure.

Unsafe Nozzle

Here is an example of a nozzle that is dangerous.  As you can see, there is only one path where the air can pass through.  Other similar types of blow-off devices that would fall into this same group would include copper tubes, flexible lines, and open pipes.  They are dangerous as compressed air cannot escape if it is blocked by your body or skin.  If operated above 30 PSIG (2 bar), these nozzles could penetrate the skin and create an air embolism within the body, which can cause bodily harm or death.  This is a hazard that can be avoided by using EXAIR Super Air Nozzles and Safety Air Guns.  The nozzles are designed with fins, which allow the air to escape and cannot be blocked by your skin.  So, you can use the EXAIR Super Air Nozzles safely above 30 PSIG (2 bar) and remain OSHA compliant.

Unsafe Air Gun

To counteract the dead-end pressure violation, some nozzle manufacturers create a hole through the side of the nozzle (reference photo above).  This will allow the compressed air to escape, but now the issue is noise levels.  With an “open” hole in the nozzle, the compressed air is very turbulent and very loud.  The National Institute for Occupational Safety and Health (NIOSH) states that 70% to 80% of all hearing loss within a manufacturing plant is caused by compressed air.  OSHA created a chart to show the maximum allowable noise exposure.  This chart shows the exposure time and noise limits before hearing protection is required.  The EXAIR Super Air Nozzles, Super Air Knives, and Super Air Amplifiers are designed to have laminar flow, which makes them very quiet.  As an example, the model 1210 Soft Grip Safety Air Gun has a sound level of only 74 dBA, well under the noise exposure limit for 8 hours.

One of the last things that companies think about when purchasing compressed air products is safety.  Loud noises and dead-end pressure can be missed or forgotten.  To avoid any future fines or having to purchase additional personal protective equipment (PPE), it will be much safer to purchase EXAIR products.  If you would like to improve the safety of your facility and reduce energy costs, an Application Engineer at EXAIR can review your current blow-off devices.  Remember, safety is everyone’s responsibility.
