Event-related sterility depends on factors such as the handling of instruments, storage conditions, and environmental factors. The expiration date is not a factor that directly affects event-related sterility. Instead, it is crucial for items with expiration dates to be monitored and replaced before they expire to ensure sterility. Magnetic, weekly monitoring, and BI PCD (biological indicator process challenge device) are all important factors in verifying the sterility of processed instruments.
