Why does OSHA disapprove of using compressed air to blow off cars in shops without filtration systems?

OSHA disapproves of using compressed air to blow off cars in shops without filtration systems principally because it can lead to airborne dust particles contaminating the breathing air. When compressed air is used for this purpose, it can stir up a variety of contaminants, including dust, paint particulate, and other debris that may be present in the workshop environment. This can pose significant respiratory hazards to workers, as they may inhale these harmful particles, leading to potential health issues.

Implementing proper filtration systems mitigates this risk by capturing harmful particles before they can become airborne, thereby promoting a safer working environment. This aligns with OSHA’s mission to ensure safe and healthful working conditions, highlighting the importance of using equipment that minimizes exposure to hazardous substances.
