What Is Purging? |
|
Answer» PURGING is the process of supplying ENCLOSURES with compressed air or inert gas at the proper flow and pressure in order to REDUCE the hazardous gas inside the enclosure to a SAFE level. Pressurization is the process of bringing compressed air or inert gas within an enclosure to a pressure where there is no ingress of hazardous gasses or combustible gas. Both purging and pressurization are required in a ClassI,gas atmosphere. Only pressurization is required in a ClassII, DUST atmosphere.
