Well whats worse, 2nd degree burns on your arms and a headache from insurance and work or watching someone burn up in a rolled over vehicle while you just stand and watch?
*Sigh* You do not want my answer to that question.
If you want to spend months in excruciating pain while going through rehab, thats your choice. I on the other hand elect to use a thought process that will allow the best outcome for the most people; and my personal safety tops that list. My family depends on my ability to perform in the field and I enjoy my livelihood. I am not equipped nor prepared to deal with someone elses emergency off duty, I have no duty to act, I am not covered under any insurance policy, do not wish to be part of litigation, and I have the faith in our local professional resources that can effectively deal with these emergencies.
Get some experience in this industry and you will see why most of us feel this way. You cant save the world, unfortunately Darwinism sometimes does apply.
