Update: Managing Chaos; the Disaster Planner’s Handbook in Eight Parts (2013), by Mitch Stripling, City of NYC Dept. of Health and Mental Hygiene. (21 pp). This is one of the most readable and practical documents on the topic that I have ever read. I recommend it highly. [The update provides the direct URL to the document and supporting references.]
