During your slow season, you most likely service or repair your essential equipment. You should extend this line of thought to your self retracting lifelines (retractables). Guardian retractables should be re-certified every two years from the date it is put into service. Make sure this in-service date is noted on the I.D. tag. This ensures that the unit is always in proper working order in the event an accident or fall occurs. When a retractable comes in for re-certification, we inspect it to make sure that all the components are in proper working condition. The cable, locking snap hook, brakes and springs are all tested under simulated fall conditions, and any component that fails or shows sign of fatigue must be replaced. This can include the outer labels, which also act as instruction labels and an inspection chart.
