What kinds of numbers can be used within an alligation grid?

You are on the scene of a bus rollover on a rural interstate. A person states that he is a volunteer at an out-of-state fire department and that the worst patient is "over there." He insists that you follow him to this person. You can see that there are other people in and around the bus who could be injured. Which of the following best describes your role and your actions at this point?

A) Give the first responder your aid bag and tell him or her to provide care until more units arrive. Quickly assess the scene, then return to the patient. B) If you have not done so, radio a size-up. Then, you and your partner triage all persons needing care and/or rescue. Pay particular attention to the need for specialized rescue companies. C) You are overwhelmed at this point. It is not prudent for you to take action, because you will undoubtedly be unable to care for all situations that will come upon you. Do a size-up and remain in the unit until you have more resources. D) Follow the first responder; to neglect the patient after he has told you he or she needs care is negligence.
