Searchers should use a buddy system or two-in, two-out system and have backup teams available. Techniques for searching for potential victims are based on identifying possible locations of victims, or areas of entrapment. Areas of entrapment inside damaged structures are called voids. There are several types of voids, such as the pancake void, and the lean-to void. Voids can also include spaces where victims may have entered for self-protection during a disaster - such as under desks or in bathtubs or closets. Once the potential areas of entrapment have been identified and the potential number of victims sized up, search operations should commence in an orderly manner, beginning with verbally calling out for victims to identify their location if possible, and searching using a systematic search pattern. Possible search patterns include triangulation (using three searchers approaching a potential area of entrapment from three different directions), a right / left search pattern (one team searches the left side and one team the right side of a building), or a bottom-up / top-down search pattern. Searchers should stop frequently to listen for noises or attempted communication from victims; often this can involve all searchers stopping activity at specified periods of time to listen.
