NREMT Scene Size-Up & Hazard Management

Question 1

What is the first step in scene size-up?

Accepted Answer

Ensuring scene safety

Answer

The very first step in any EMS call, known as scene size-up, is always to ensure scene safety for the EMS providers, the patient, and bystanders. Approaching a dangerous scene without proper assessment can lead to further injuries or fatalities, preventing effective patient care. Only after the scene is deemed safe can providers proceed with patient assessment and treatment.

Question 2

What is considered a potential hazard at a scene?

Accepted Answer

Downed power lines

Answer

Downed power lines are an extremely dangerous hazard at an emergency scene, posing a severe risk of electrocution to anyone who comes into contact with them or the ground nearby. EMS providers must recognize such dangers during scene size-up and maintain a safe distance until the power company has secured the area. Ignoring this hazard can be fatal.

Question 3

What PPE should be worn at a motor vehicle collision?

Accepted Answer

Reflective vest, gloves, helmet

Answer

At a motor vehicle collision (MVC), EMS providers face multiple hazards including moving traffic, broken glass, sharp metal, and potential head injuries. A reflective vest ensures visibility to oncoming traffic, gloves protect against cuts and exposure to bodily fluids, and a helmet provides head protection from falling debris or impacts. This PPE is essential for personal safety in such environments.

Question 4

What should EMS providers do at a hazardous materials scene?

Accepted Answer

Withdraw and call hazmat resources

Answer

At a hazardous materials (hazmat) scene, the immediate priority for EMS providers without specialized training is to withdraw to a safe distance and call for trained hazmat teams. Attempting to enter a hazmat zone without proper PPE and training can lead to severe injury, contamination, or death. Patient care can only begin once the scene is decontaminated and declared safe by hazmat specialists.

Question 5

Why is scene size-up ongoing?

Accepted Answer

It’s an ongoing process

Answer

Scene size-up is not a one-time event but an continuous process throughout the entire call, from arrival until departure. Hazards can emerge or change, patient conditions can deteriorate, and new information may become available. Constantly reassessing the scene ensures ongoing safety for providers and allows for adaptation of patient care strategies.
