A heavy structural collapse can result from terrorism, earthquakes, hurricanes, floods, and tornadoes or from poor structure design. Rescuers must know how to operate many tools to remove steel and concrete debris. At some time in their careers, firefighters may need a crane to remove heavy objects to access trapped victims (called “selective debris removal,” stage four of the universal five-stage collapse and rescue operations protocols). A crane can help to remove steel I-beams, reinforced concrete, and other heavy material that would slow the rescue of trapped victims. In operations at the 1995 Oklahoma City Bombing of the Alfred P. Murrah Federal Building, a crane was a major asset. Certified crane operations personnel who can work in conjunction with local firefighters, special operations teams, and other rescuers are a valuable resource.
