What is the leading cause of sterilization failure?

Steam penetration and airflow are essential for effective sterilization. When you overfill the sterilizer, items press against each other and the chamber walls, trapping air pockets and blocking steam from circulating freely. That obstructed circulation prevents heat from reaching all surfaces for the required exposure time, creating cold spots where microbes can survive. Because of this, overloading most commonly leads to sterilization failure. Underloading can waste capacity and alter efficiency, but it typically doesn’t create as many sterilization failures as packing too full. Packaging issues and too-short cycle times can also compromise effectiveness by hindering steam contact or reducing exposure, but the primary, most preventable problem is loading the chamber too full.
