When it comes to OSHA and their standards in regard to compressed air, it boils down to two main topics. OSHA standard 1910.242(b) and 29 CFR-1910.95 (a).<\/p>\n
OSHA standard 1910.242(b) \u2013 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. <\/strong><\/em><\/p>\n 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\u2019t 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\u2019s body. The \u201cdynamic\u201d pressure, which is the speed of the air as it flows from the nozzle, can be much higher, provided that the static pressure \u201cDead end Pressure\u201d remains under 30 psi when the nozzle is obstructed. This is why it\u2019s crucial for employers to educate their workers about the dangers of compressed air and the significance of not modifying air nozzles.<\/p>\n Our\u00a0Air Nozzles and Jets<\/a>\u00a0video 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\u00a0Super Air Knife<\/a>\u00a0may 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.<\/p>\n \n
