Which action is NOT part of the scene size-up process?

The action of donning personal protective gear is not considered part of the scene size-up process. The scene size-up is an essential initial phase in emergency medical response, focusing on gathering critical information to ensure the safety of both the responders and the patients.

The scene size-up involves assessing the need for assistance, which helps determine whether additional resources are required based on the nature of the incident. Determining if the scene is safe is crucial for ensuring that the EMTs and other responders are not exposed to any potential hazards that could jeopardize their safety or the safety of bystanders. Evaluating the mechanism of injury provides insight into the possible injuries that victims may have sustained, guiding the treatment approach.

While personal protective gear is vital for ensuring the EMT's safety during patient care, the act of putting it on is more of a preparatory step that occurs before or in conjunction with the scene size-up rather than a direct part of it.
