Before initiating first aid, the provider needs to assess the situation. If the environment is hazardous, steps may need to be taken before first aid may commence. Effective first aid will not be possible, if either the provider or the victim is in danger of further injury. Only after ensuring that first aid can be provided safely should care actually be provided.
The answer can be A or B. To find out why, we must consider the chances. C is a probable answer but it might not be the first thing taught. D goes against the question which makes it wrong. Now to check between A or B. Emergency respondents will still enter the dangerous area because they know how to handle the situation. This makes A wrong. The answer is B because theoretically, in a scenario, any action can lead to a series of events. Lets say someone needs the defibrillator. First off, there must be no electronic appliances or loose cords in the room. Next, when the Defibrillator say shock we must makes sure no one is having physical contact with the patient or else the shock can cause more problems to a bystander. This is why the situation must be perceived in different perspectives. It is to makes sure the live people are still OK, and that no one else gets hurt. <span />
