OQ is aimed to confirm that the power / process / instrument are operating effectively, and which the reaction of critical elements (e.g. sensors) match Along with the supposed values and inside the desired vary.

Zone 1: Locations prone to have ignitable concentrations of flammable gases or vapors under standard running ailments.

Each individual HEPA filter must be tested and monitored periodically (e.g. per year or every single two many years). It's important to be aware of When they are broken.
