Backing vehicles and equipment are common causes of struck-by injuries and can also cause caught-between injuries when backing vehicles and equipment pin a worker against an object. Struck-by injuries and caught-between injuries are two of the four leading causes of workplace fatalities. The Bureau of Labor Statistics reports that in 2013, 67 workers were fatally backed over while working. While many backing incidents can prove to be fatal, workers can suffer severe, non-fatal injuries as well. A review of OSHA's Integrated Management Information System (IMIS) database found that backing incidents can result in serious injury to the back and pelvis, fractured bones, concussions, amputations, and other injuries. Emerging technologies in the field of backing operations may prevent incidents. The technologies include cameras and proximity detection systems. The use of spotters and internal traffic control plans can also make backing operations safer. The Agency has held stakeholder meetings on backovers, and is conducting site visits to employers, and is developing a standard to address these hazards.
