2. Sanitation
Keeping something free of any elements that would endanger health.

3. Types of Sanitation
Cleaning: Physically removing all visible signs of dirt and organic matter such as feces, blood, hair, etc.

4. Disinfecting: destroying most microorganisms on nonliving things by physical or chemical means.
Sterilizing: destroying all microorganisms and viruses on an object using chemicals and/or heat.
Antiseptics: solutions that destroy microorganisms or inhibit their growth on living tissue.

5. Commonly Used Chemicals
Alcohols: Effective against gram positive and negative bacteria
Usually diluted to 60-70%
Irritating to tissue
Used as a solvent for disinfectants and antiseptics
Examples: ethyl alcohol, isopropyl
alcohol, ethanol

6. Aldehydes: effective against gram positive and negative bacteria, fungi, and most viruses
Irritating and toxic to tissues
Examples: gluteraldehyde, formaldehyde

7. Chlorine: Effective against gram positive and negative bacteria, fungi and most viruses
Cheapest, most effective chemical disinfectant
Irritating and toxic to tissues
Example: bleach

8. Iodine and Iodophors: Effective against gram positive and negative bacteria and fungi
Usually used in solution with water and alcohol
Iodophors=iodine mixed with detergent to use as a surgical scrub
Stains and irritates tissue
Examples: Betadine

9. Quaternary ammonias: effective against gram positive bacteria and some gram negative bacteria, some fungi and some viruses
Deodorizes
Examples: Centrimide, Quatsyl-D

10. Methods of Sanitation
Physical Cleaning: using a chemical with a mop or sponge (ex. Scrubbing a patient for a surgery or mopping a kennel floor)
Cold Sterilization: soaking items in a chemical disinfectant until they are used.

11. Dry Heat: incinerating an object or exposing it to flame (ex
Dry Heat: incinerating an object or exposing it to flame (ex. Burning infected tissue)
Radiation: using ultraviolet or gamma rays. (UV are used to sterlize rooms; gamma sterilize rubber, plastic, gloves and suture material). VERY DANGEROUS and expensive to use!

12. Filtration: removing particles from the air using a physical barrier (ex. Using facemasks, gloves and gowns or a ventilation system)
Ultrasound: passing high frequency sound waves through a solution to create a vibration that scrubs an object to remove debris. (commonly used as a method of cleaning instruments)

13. Autoclave: a sealed chamber in which objects are exposed to heat and steam under pressure. (used to sterilize items used in surgery)
