Home   >   About safe site


In 1997 Safe Site BV was founded by brothers David and Emile Sassenburg. It all started by selling fall arrest harnesses, hooks, and lines. From a small warehouse in Capelle aan den IJssel the sales of these products was an instant success. Soon after, Safe Site BV expanded and added other services to the fall protection scope: training, inspection and installation. Since then, we have kept on growing to the allround fall protection company it is today. With our approximately 20 workers, we enjoy servicing you every day!
