Environmental Control includes physical and chemical processes. Some examples of physical control methods are:
Sterile - Free from all life forms, including viruses.
High Level Disinfectant - Kills all life forms except endospores.
Mid Level Disinfectant- Kills all life forms except endospores, encapsulated mycobacteria, viruses
Low Level Disinfectant -Kills vegetative bacteria, enveloped viruses, and some fungi.
Aseptic -Free of pathogenic organisms and without addition during a procedure.
Sanitized- Mimimized to what is considered safe.
Pasteurize- High heat/short time. Minimizes number of bacteria in food products and juices without harming food.
Degerming Agents:
Antimicrobial
Antibacterial
Antifungal
Antiviral

HOSPITAL SETTINGS
Critical Level Items- are items that penetrate the epithelial layer of tissue, therefore, they must be sterilized.(Needles, scissors, etc.)
Semi-Critial Items -Do not penetrate the epithelial layer but may enter a cavity. Sterilization of these items is not required. (Endoscopes, speculas, etc.)
Non-Critical Items -Do not break the tissue or enter into any cavity. (stethescopes, bp cuffs, etc.)
