All air guns operate on compressed air—compressed air that can be extremely dangerous if misused, or if horse-play in the workplace occurs. Not only can workers be severely injured from the use of non-compliant, illegal air guns, but compliance failures can mean steep fines for violators. Although OSHA Standards pertaining to air guns can be confusing, OSHA's three primary concerns are Noise, Output Pressure and Chip-Guarding.

To address excessive noise in the workplace OSHA has developed permissible daily noise exposure specifications. Since air guns can potentially contribute to high levels of occupational noise, Guardair safety air guns incorporating noise suppression nozzles can be an important component in moving towards noise level compliance.

Guardair recommends the use of noise suppression nozzles and/or hearing protection equipment as part of a comprehensive noise control program.


Factory air compressors and air lines nominally operate at pressures between 80 and 120 psi (pounds per square inch). Most pneumatic tools, including air guns, require such high pressures to operate effectively. However, OSHA Standards requires that in the event such air lines are dead-ended (i.e. if the tip of an air gun is blocked) the static output pressure at the point of the blockage may not exceed 30 psi. All Guardair safety air guns incorporate nozzle designs which are engineered to meet, or exceed, this 30 psi requirement.OSHA Standard and Instruction Related to Output Pressure

Guardair recommends the use of OSHA compliant safety air guns to insure that static output pressure does not exceed 30 psi.


When blowing off debris with an air gun in close quarters, workers may be subject to "chip fly-back." This term refers to the tendency of loose particles or chips to fly back into the operator's face, eyes or skin. For operations that require close-in work, OSHA mandates that "effective chip guarding" be incorporated into the workplace. Effective chip guarding means methods or equipment that will prevent chips or particles from flying back at the operator. Guardair offers several safety air gun models incorporating the Air Shield nozzle, which protects the operator from chip fly-back.
