Let's say that there is a disaster in a city in which you are holding a meeting -- or even elsewhere -  necessitating quarantine of all your guests in the facility.  Some of the guests (some  or all of whom are attending your meeting) have medical needs and only limited help is allowed to bring medications and other necessities to the facility. (Assume the facility is a hotel or a convention center.) NO ONE is allowed to leave and it is unclear when anyone will be allowed to leave.   

Say that the facility itself does have some things in place, that all that is in place is in writing, and that they believe there are sufficient supplies for at least 2-3 days, what they believe is enough.  

 There is of course anxiety among those who are there but they are willing to believe that things will turn around.   On day 2, power is lost - and the back up generators only power some of the facility.  Later on day 2, those too go out and there is now no power.   People are getting sick -- from heat or cold (this doesn't yet specify what time of year) -- their medications have run out -- there is no ability to cook food and there is waste backing up inside bec. pumps are not working among other problems. 

With something like a disaster, there are many other things that go wrong -- assume it's 'most everything.   There is a rumor that some will be able to be able to leave the facility; no system however is in place to determine who will and why and when.    What is the chain of command you might follow? How and when would that be determined if it hadn't been at the outset of the meeting? Who will decide who can leave -- will it be those who have illnesses that need immediate attention? Or?  

(This is NOT a debate about healthcare -- I promise! -- it is about disaster preparedness.)   Let's discuss.  Let's see where we go w/ this.
