Answer:
The first thing you should do when approaching the scene of an emergency is to assess the situation and determine if it is safe to proceed. This includes looking for any potential hazards, such as fire, chemical spills, or unstable structures, and taking appropriate precautions to protect yourself and others. You should also try to determine the extent of the emergency and the number of people affected, as well as any available resources that can be used to assist those in need. Once you have completed this initial assessment, you can then begin to take appropriate action to address the emergency and provide assistance to those in need.
