If the evacuation process is being conducted due to some emergency, it is likely that persons present will want to use all available exits, and keeping track of “who remains” would become very difficult.  One of the first thing emergency responders, upon arriving on scene, want to know (whether it is a house fire or some other incident) is whether there is anybody “still inside and/or at risk”.  (The language they use is:  “Is the building clear?”)  Large events inherently make a definitive answer to this question very difficult since it nearly impossible to guarantee this unless you have the kind of accounting system that is the subject of this email thread, and it works perfectly.

 

And, the truth is that the Incident Commander may or may not actually believe what he or she is told, anyway.  The decision to be made quickly is:  are we going into “rescue mode” or “put out the fire” mode?  These are different strategies, and requite different tactics.  The IC has to judge the reliability of the information given, and then made a decision about the primary goal of “life safety” or the secondary goal of “property conservation”, (along with deciding about what level of risk to which his/her crew should be exposed).  If someone tells me, as the IC, “I think everyone is out”, I have to assume that they might be wrong, and go into life rescue mode.  If they say, “I’m absolutely certain that everyone is out”, then I have to judge their reliability, cross my fingers and hope I make the right judgment.  If things “go south” and lives are lost based on a mis-judgment, it will be a bad day on many levels, including post-incident explanations.

 

All of this relates to the initial question:  for a large incident, what are the odds that the accountability system will be flawless, and that the local contact person can tell the IC, “I am absolutely confident that no one is inside”?    I would be skeptical of this information as the IC, even when it is delivered with the best of intentions.   I’m not sure what kind of incidents are envisioned in the original question.   If some technology appears to solve this, I’d encourage some consultation with the local fire department that candidly asks, “Would the IC believe me/us if I deliver the information that all 256 people are evacuated?”

Subject: [DCHAS-L] Query: Roll call capabilities at Rally Points

 

DCHAS Members,

 

Has anyone utilized a system (aside from physical head counting) of personnel at a rally point during an evacuation? Specifically where a building has a large population (>200).

 

Is there a computerized system available? A portable ID Badge reader system available?

 

Any feedback would be appreciated.

 

Thank you in advance.

 

-George
