In 2021, I wrote an article regarding OSHA’s Permit-Required Confined Space standard and reclassifying PRCSs to a Non-PRCS status. This article centered on the keyword “potential” when discussing a hazardous atmosphere. The intent of that article (Defining and Quantifying “potential hazardous atmosphere”) was to clarify when/how a POTENTIAL was present to create a Hazardous Atmosphere.
