The trench cut is a valuable tool that is in the IC's "tool cache". Much consideration should be made before deciding to incorporate this tactic. The defensive posture of saving a portion of the building will result in writing off a section of the structure. The manpower and equipment needs of this tactic will require the progressive IC to call for multiple alarm companies early in the incident so they are on-hand to be deployed early in the fire. Delaying the start of this tactic will increase the loss of the property, to a potential level that the entire structure may be a total loss. Thanks to today's technology, it is not necessary to go out for hours on end and do roof surveys; programs like Google Earth and Bing Maps can allow you to view your first due response area for potential trench cut operations, and preplan alarm assignments before the fire.
Until next time, stay focused and stay safe.
