A contractor demonstrates how the self-retracting lifeline (SRL) works on the new fall protection system during a training session at Dobbins Air Reserve Base, Georgia, Oct. 16, 2020. In the event of a fall, the SRL locks in place, much like a seatbelt in a car, and prevents them from hitting the ground. The 94th Aircraft Maintenance Squadron recently acquired several mobile fall protection systems to improve the safety of maintainers and operators as they perform their duties on the aircraft.
