Much of this call to reality centers around capability and resources. This Decontamination Chart (PDF)
is designed to examine and compare the different types of decon, the set-up times, and the decon rates for people. It behooves response agencies to examine where their capabilities lie and prepare accordingly.
While the goal of decontamination efforts is to prevent the spread of contaminants and reduce the effects of chemical and other agents on people, the process is fairly simple. Emergency decon simply uses large amounts of water to flush off contaminants and it can be employed fairly quickly, with easily acquired equipment, and without a large demand for personnel. Technical decon may be best employed at sites where victims may travel to seek medical assistance. It is by nature more thorough and arduous to complete. The whole goal should center around speed of implementation. How can responders do the most good in the shortest period of time?
So, is your jurisdiction ready for a terrorist attack? Hopefully, this article provides some food for thought and empowers you to rethink your decontamination efforts in response to terrorism attacks. Author Scanlon adds: "Experience suggests that the current approach won't work. Surely we can make the necessary changes before it is too late."
