Can compressed air be used for cleaning purposes?
Questions: Section 1926.302(b)(4) provides that “compressed air shall not be used for cleaning purposes except where reduced to less than 30 p.s.i. and then only with effective chip guarding and personal protective equipment which meets the requirements of subpart E of this part.
What air pressure is recommended for cleaning?
The Occupational Safety and Health Administration (OSHA) standard 29 CFR 1910.242 (b) requires that the nozzle pressure of an air gun used for cleaning purposes remain below 30 pounds per square inch (psi) for all static conditions. In the workplace, pressure to air guns can range from 55 to 160 psi.
Can you get an embolism from compressed air?
Air Embolism
When high-pressure compressed air is used to clean skin and clothing, it can penetrate the skin and enter the bloodstream. This, in turn, can cause blood vessels to become blocked by air bubbles, triggering stroke-like symptoms. If left untreated, an air embolism can lead to coma, paralysis and death.
