In electrology, the categorization of objects based on contamination levels is primarily structured around the concepts of critical, semi-critical, and non-critical items. This classification helps professionals assess the level of risk associated with each type of item and determine the appropriate methods for cleaning, disinfection, and sterilization.

Critical items are those that come into direct contact with sterile body tissues or the vascular system; they require stringent sterilization to eliminate all forms of microbial life. Examples include needles and surgical instruments.

Semi-critical items come into contact with mucous membranes or non-intact skin and require high-level disinfection, as they need to be free from all microorganisms except large numbers of bacterial spores. Examples include devices used for skin contact or facial treatments.

Non-critical items only come into contact with intact skin and pose a lower risk of infection; they can usually be cleaned and disinfected rather than sterilized. Examples would include items such as examination tables and countertops.

This classification system ensures that electrologists are properly trained in infection control practices and can maintain a safe, sanitary environment for their clients.
