To keep patience and cool
To successfully come out from a situation of sheer test one must have patience and cool head other than the emergency tools. Though it might seem to be a simple thing to discuss but I have felt that on situations of real test it becomes really a challange to keep the cool and patience.
Assess everything around you
In a danger situation/emergency/crisis (I've been in a few in a number of settings) I've found that sort of taking a step back and quickly looking over the entire situation helps one not only stay cool, but act competently dealin with whatever the situation is. One of the reasons I mention this is because someone posted about how some people always stay...you know, way cool, be aware of anyone who seems so cool that nothing is bothering them. Give them a job to do, you might be staving off shock for them. Encouraging anyone involved in the emergency to help creates a positive sense of team work and makes less work for each person. some people might say ...hey! who put this yo-yo in charge? but for the most part...at post-crisis time, people are going to reflect back and say "man (he or she) is cool!)
Patience usually just means the ability to wait for a situation to happen or resolve itself, and really, what does that require? Nothing. That's why most of us don't have patience, we really aren't geared to do nothing. Patience can definitely be learned, but if you don't have some, I'd recommend don't take up fishing or hunting :D
