How should hinged instruments be placed in the sterilizer during processing?

Hinged instruments should be placed open and unlocked in the sterilizer during processing to ensure that the sterilizing agent can access all areas of the instrument effectively. When instruments are open, the sterilant can penetrate the joints and crevices where blood and debris may accumulate, thereby allowing for thorough sterilization. This method also facilitates drainage of any residual moisture, which is crucial for effective sterilization and to prevent the growth of microorganisms.

Placing hinged instruments closed and locked may prevent the sterilant from reaching all surfaces, while using trays or plastic bags can impede the necessary exposure to the sterilizing agent unless specifically designed to allow for appropriate circulation around the instruments.
