6Developed as a supplement to the FEMA Rescue Operations Guide and the US Army Corps of Engineers Structures Specialist Field Operations Guides by the National Association for Search and Rescue.

This waterproof, pocket-sized reference guide is an essential in-field tool that fits easily into a BDU pocket or radio chest harness and supports the urban search and rescue response as performed by FEMA and other Task Force members.
