Why should responders wear PPE during arrival and scene size-up?

• A. PPE should be worn to protect against hazards on the scene.
• B. PPE is optional if the scene looks safe.
• C. PPE should only be worn after patient extraction.
• D. PPE is unnecessary if weather is good.

Answer: (A)

Protecting responders from hazards at the scene is essential, and putting on PPE during arrival and scene size-up is the first line of defense. The moment you arrive, you don’t know exactly what hazards you’ll face, and some dangers aren’t immediately visible. PPE acts as a barrier against bloodborne pathogens, bodily fluids, sharp objects, chemicals, smoke, and other environmental risks, helping prevent exposure and cross-contamination as you evaluate the scene.

Scene size-up is a quick risk assessment that guides what PPE is appropriate. You assess traffic, structural stability, hazardous materials, lighting, weather, and other factors, then don the needed protection to proceed safely while you gather more information and begin patient care. Waiting until after contact or extraction increases the chance of injury or contamination.

Weather or not the scene looks dangerous doesn’t determine the need for PPE, since many hazards are independent of conditions and can emerge unexpectedly. In short, PPE during arrival and size-up is about reducing risk and keeping both responders and patients safer from the outset.
