Here on the EXAIR Blog we frequently discuss dead-end pressure as explained in OSHA Standard 1910.242(b). This directive states that the when compressed air is used for cleaning purposes, the dead-ended pressure must not exceed 30 psig. When pressures greater than this occur, there is potential for an air embolism. This animation shows and explains how an air embolism can affect the body.
EXAIR’s Flat Nozzles adhere to this OSHA directive. The Flat Nozzles consist of three primary components: the body, the cap, and the shim. The thickness of the shim will dictate the flow and force through the nozzle and can be easily adjusted. The cap slightly protrudes from the body and shim, creating a gap when it is pressed up onto the skin. By ensuring that there is always an avenue for that air to escape, there is no potential for it to be dead-ended.
EXAIR’s flat nozzles are available in two sizes: 1” and 2”. Each size has a shim set that can be purchased for adjusting both the flow and force from the nozzle. These nozzles are available in both zinc/aluminum alloy as well as 316 grade Stainless Steel. They can be used by themselves, installed on our Safety Air Guns, or in conjunction with our Stay Set Hoses that allow for easy re-positioning.
You may have seen (or used) the plastic flat nozzles that come in a variety of different colors. EXAIR’s flat nozzle is a safe, efficient, and more robust replacement that will maintain a similar airflow pattern at a dramatically reduced operating cost. Where plastic nozzles may become damaged or break off, the rigid construction of EXAIR’s Flat Nozzle will not. In addition to be safe, durable, and reliable, EXAIR’s flat nozzles also offer a reduced sound level compared to these styles of nozzle. Reducing sound is another directive that OSHA 29 CFR 1910.95 covers. If you’re using an unsafe nozzle in your facility, OSHA can quickly begin assessing fines for each violation. They don’t announce their visits beforehand, so make sure you do your due diligence and assess your compressed air blowoff products yourself!
