With regards to your comment:
b) is it safe for me to get and be near the patient?
Is this where you include "Secure the scene so that no one else gets hurt" including me.
Yes, that's exactly what I mean. The patient may not like it much, but it's worth it for me to delay aid for 120 seconds so I can park a truck the correct way to block traffic and still be useful on the scene.
I'm not going to run up to a vehicle leaking fuel without first advancing a CHARGED handline - and that's a hard instict to overcome, but a dead or disabled me isn't going to do anyone any good later.
Scene safety is SO important.
