NREMT EMT 1 Scene Size Up and Safety Standard precautions and body substance isolation BSI

What This Is

Standard Precautions and Body Substance Isolation (BSI) are safety measures to prevent the spread of infectious diseases when interacting with patients. Imagine you're a paramedic responding to a call with a patient who has a mysterious rash. You need to protect yourself and others from getting infected. Standard precautions and BSI are like wearing a hazmat suit to keep you safe.

• Communication: Communicate with patients and colleagues about potential infectious diseases.
  • Why: To prevent the spread of microorganisms.
  • Example: Inform colleagues about a patient's potential infectious disease.

What Laypeople Can Do

• If you're a bystander, stay at least 3 feet away from the patient to prevent airborne transmission.
• If you need to touch the patient, wear gloves if available.
