Guidelines for Standard Precautions


Standard precautions are precautions taken to avoid contracting various diseases and preventing the spread of disease to those who have compromised immunity. Some of these diseases include human immunodeficiency virus (HIV), acquired immunodeficiency syndrome (AIDS), and hepatitis B (HBV). Standard precautions are needed since many diseases do not display signs or symptoms in their early stages. Standard precautions mean to treat all body fluids/ substances as if they were contaminated. These body fluids include but are not limited to the following blood, semen, vaginal secretions, breast milk, amniotic fluid, feces, urine, peritoneal fluid, synovial fluid, cerebrospinal fluid, secretions from the nasal and oral cavities, and lacrimal and sweat gland excretions. This means that standard precautions should be used with all patients.

1.  A shield for the eyes and face must be used if there is a possibility of splashes from blood and body fluids.
2.  If possibility of blood or body fluids being splashed on clothing, you must wear a plastic apron.
3.  Gloves must be worn if you could possibly come in contact with blood or body fluids. They are also needed if you are going to touch something that may have come in contact with blood or body fluids.
4.  Hands must be washed even if you were wearing gloves. Hands must be washed and gloves must be changed between patients. Wash hands with at a dime size amount of soap and warm water for about 30 seconds. Singing “Mary had a little lamb” is approximately 30 seconds.
5.  Blood and body fluid spills must be cleansed and disinfected using a solution of one part bleach to 10 parts water or your hospital’s accepted method.
6.  Used needles must be separated from clean needles. Throw both the needle and the syringe away in the sharps’ container.  The sharps container is made of puncture proof material.

7.  Take extra care in performing high-risk activities that include puncturing the skin and cutting the skin.
8.  CPR equipment to be used in a hospital must include resuscitation bags and mouthpieces.


Special precautions must be taken to dispose of biomedical waste. Biomedical waste includes but is not limited to the following: laboratory waste, pathology waste, liquid waste from suction, all sharp object, bladder catheters, chest tubes, IV tubes, and drainage containers. Biomedical waste is removed from a facility by trained biomedical waste disposers.


The health care professional is legally and ethically responsible for adhering to standard precautions. They may prevent you from contracting a fatal disease or from a patient contracting a disease from you that could be deadly
