Wait a minute. Your *third* step is scene safety?!? That is my first! Then, and only then, call 911. What good does it do to call 911 if people are shooting at you or if after the call you are wiped away by a logging truck? Always always always always always always always make sure that your location is secure before you do anything. And I would also add, constantly reevaluate that security. Stuff can go south in a big frickin hurry, and, oh buddy do you feel stupid and scared when all of a sudden the wacked out dude on speed, who was supposed to be somewhere else, is now between you and your partner with the pt, and somehow the idiot cops are in the other end of the house. And all you are holding is the clipboard. Or (and I did not experience it personally though) the transmissin line abouve you attached to the pole the vehicle hit has been arcing for the past 5 minutes, starts dripping insulation about 30 feet aylway, and then explodes. Constant reevaluation of safety and security can prevent you from being there in those situations. Nothing is more importaint than scene safety and security. Nothing. At the worst, you remove yourself from the sene and then call 911.
Sorry bout the thread jacking. End of rant. :-/
