You may have had a visit from OSHA (or other regulating authority) in the past. We have had them here and we also speak to customers daily who have had the pleasure. Typically our customers need to address a pressure or noise violation, and need help finding the right product to get them right with OSHA.
Recently, I spoke with a customer that was visited by OSHA (Occupational Safety and Health Administration). If you do not know, OSHA is a federal agency charged with the enforcement of safety and health. In order to protect workers, they can enforce fines and penalties for violations. This customer had a very common violation with their compressed air guns. They were too loud, and they may not meet the dead-end pressure requirement. Many companies will modify their compressed air guns to better fit their application. The problem occurs when they modify them to the point that the products no longer meet the OSHA standards. You have to make sure that you meet 29CFR Part 10910.95 (a), which addresses the maximum allowable noise exposure your personnel can experience, and 29CFR Part 1910.242(b) which addresses the maximum pressure allowable at the outlet of an air product.
My customer sent me a picture of the compressed air gun that they were currently using (shown below). The problem was the noise level was too high. With this “open pipe” design of a nozzle, the noise level was exceeding 100 dBA. This was a major concern. The number of hours that an operator used this noisy air gun exceeded the OSHA exposure limit. The customer called EXAIR because he needed to replace his existing air guns with quiet safety air guns. The main component of an air gun is the nozzle. It is like buying a great paint gun, and if the spray nozzle is cheap, you cannot lay a nice spray pattern of paint.
In his application, he needed 6” (152mm) to reach into and around his product. I suggested a model 1310-6 Heavy Duty Safety Air Gun with a 6” extension. With the model 1100 Super Air Nozzle attached, the noise level was decreased to 74 dBA, and if checked by OSHA, it will not exceed the 30 PSIG pressure standard either. With the unique design of the nozzle, it entrains ambient air to help create a powerful force to remove the chips. With the 1310-6 Heavy Duty Safety Air Gun, the customer was happy and OSHA was happy.
We are all individually in charge of safety. To help meet the OSHA standards, EXAIR has a variety of Safety Air Guns and nozzles to make your operation quiet and safe. It can become very costly if you are in OSHA violation. If you need help in determining which product would best fit your application, you can contact us at EXAIR at 800-903-9247 and speak to one of the Application Engineers.
