What is the first question you should ask yourself under the "check phase"?

• A. Is the scene safe (check phase of flight, debris, bodily fluid)
• B. Are there any injuries
• C. Do you need air
• D. Is the weather good

Answer: (A)

The first thing to assess is scene safety. Before you do anything else, you must determine whether approaching the scene could put you or others at risk—look for hazards like debris, spills, weapons, or unstable surroundings and ensure you have a safe path and the proper protection. If the scene isn’t safe, you pause, call for help, and secure the area. Only after confirming safety do you proceed to check for injuries and decide what care is needed. The other steps (looking for injuries, deciding if you need to open an airway or provide air, or considering weather) come after establishing safety, not before. Weather can influence safety, but it doesn’t replace the need to assess immediate hazards first.
