How do you validate EtO sterilization?
The common approach for ethylene oxide sterilization (EO sterilization) validation is referred to as the “Overkill Approach,” in which a biological indicator, placed in the most resistant location of the device, is deactivated or killed in one-half the time of the routine sterilization cycle.
Is sterilization FDA approved?
FDA recognizes many of these standards. This means FDA finds them acceptable. A list of recognized sterilization standards appears at FDA’s Center for Devices and Radiological Health (CDRH’s) web site. NOTE: Many device manufacturers use contract sterilizers for sterilization of their devices.
What is EO gas sterile?
Ethylene oxide (EO) sterilization is the most common industrial sterilization technique for medical devices. It is a relatively ‘cold’ sterilization technique and offers high compatibility with most materials used in the manufacture of medical devices, such as plastics, polymers, metals and glass.
How do you confirm sterilization?
Biological indicators, or spore tests, are the most accepted means of monitoring sterilization because they assess the sterilization process directly by killing known highly resistant microorganisms (e.g., Geobacillus or Bacillus species).
How does EtO sterilization work?
EtO is known as a powerful sterilant. The simple answer is that ethylene oxide rips apart cell membranes, causing microorganisms to die. Ethylene oxide is a colorless, flammable gas.
What birth control is FDA approved?
The Food and Drug Administration (FDA) approves the world’s first commercially produced birth-control pill–Enovid-10, made by the G.D. Searle Company of Chicago, Illinois.
Is EO harmful to humans?
Chronic (long-term) exposure to ethylene oxide in humans can cause irritation of the eyes, skin, nose, throat, and lungs, and damage to the brain and nervous system. EPA has concluded that ethylene oxide is carcinogenic to humans by the inhalation route of exposure.
What is a Class 3 indicator?
Class 3: A specific variable indicator is created to purposely show the exposure to a single sterilization procedure at a stated value of the identified variable. For example, a specific variable is a temperature tube that hosts a chemical tablet which melts at an identified temperature.
What are 3 forms of sterilization monitoring?
The effectiveness and proper performance of a sterilizer must be confirmed through a combination of three types of monitoring: physical or mechanical, chemical and biological.
