Phases of Structural Collapse Rescue Operations
There are generally five phases of rescue operations at collapse incidents:

Phase One: Assessment of the area, control of utilities and crowd, location of obvious victims, evaluation of building stability
Phase Two: Safe and rapid removal of surface victims
Phase Three: Search of accessible voids and spaces for victims
Phase Four: Selective debris removal
Phase Five: Complete debris removal

NFPA 1670 is a must for organizations that respond to technical rescue incidents
This vital Standard identifies and establishes levels of functional capability for conducting operations safely and effectively. It's intended to help the AHJ assess a technical rescue hazard within the response area, identify the level of operational capability, and establish operational criteria. (Approx. 72 pp., 2004)
