I do think cars can explode, I have heard that when the gas tank is near empty an explosion is more likely because it is the gas fumes that are explosive, not the gas itself. And yes I just jump right in there during an emergency and fall apart later.
when I was pregnant with my first daughter in 1981, I was taking CPR classes. I already had 2 sons and 2 stepchildren a son and daughter I was about 7 months into my pregnancy and was on my way to pick up my husband from work. I had all the kids in the car and I was driving on a rural road when I noticed some doings in the road ahead, I thought a dog had been run over, as I slowed and came closer, I saw that it was a child. I stopped well back so the kids wouldn't see. I ran as fast as my pregnant body would allow, and a teenage boy was leaning over the little girl. As I approached I hollered, is she still breathing. He said, "she just quit"
I knelt beside the 8 year old and checked for breathing. I had only taken 2 classes-all I knew was how to check for respiration and heart beat. Her heart was beating. I also knew that you can encourage breathing by tipping the head back to open the airway, so that is what I did.
She began to breath. Her eyes were open and her pupils were completely dilated - not a good sign. By this time cars from both directions were stopped and someone had called an ambulance. Her parents came out of their house and her grandparents happened to come by. I had someone get a blanket out of their car to cover the little girls legs, which were each broken in several places. I didn't want her parents and grandparents to see those legs.
I cradled her chin in my hand, and hoped the ambulance would arrive soon.
That evening the hospital called to tell me that the girl had died shortly after arriving at the hospital. We had a family cry, my husband and I grieved for the girl and her parents and the kids cried because Mommy and Daddy were crying. I cried off and on for days.
About two weeks later, with CPR classes completed, we were on our way to the Kingdom Hall for field service, and saw a car had run off the road, my husband and I were the first ones on the scene. We stopped and jumped out. The elderly man was not breathing and had no pulse. We pulled him out of his car and began CPR. I had to remove his dentures, couldn't get a seal-the dentures were too loose.
My husband did the breaths and I did the compressions. When each breath he put in came out, it was accompanied by a ghostly sound, ooohhh. It honestly sounded like a ghost in a cartoon. Each breath did that. The man began to have a pulse, I quit compressions. Again the hospital called that night to report that he had another heart attack once arriving at the hospital, he died.
Another family sob fest ensued.
I have never used my training before or since. Fairly odd that these things should happen at the time we were taking the classes.
When emergencies happen, your thinking brain kicks out and your training and heart kick in. You just do what has to be done, plenty of time to cry and react later. Long story short-of course I would help pretty much no matter what, no thinking involved you just DO it.
