What should you ensure before performing CPR on someone?

Before performing CPR, it is essential to ensure that the scene is clear of hazards. This step is crucial for the safety of both the rescuer and the victim. If the environment is dangerous—whether due to traffic, fire, electrical hazards, or other risks—attempting to perform CPR could put you in harm's way and hinder your ability to help the victim effectively.

By assessing the scene first, you can protect yourself and ensure that you can proceed with giving aid. This consideration is particularly important because any distractions or dangers could lead to further injury or complications for both the victim and the person performing CPR. Once the area is confirmed to be safe, you can then focus on providing the necessary care without risking personal safety or the success of the rescue effort.
