Fall Clearance

Secure Anchor Systems recommends the design or use of any anchorage system when working at heights by way of a fall restraint methodology.  Whenever fall arrest systems are utilised or there is a consideration of designing a fall arrest system, it is absolutely essential that adequate clearance be available below any fall edge.

This is essential as, a user in the event of a fall regardless of equipment and it’s correct usage may suffer injuries due to striking the ground or projections from building facades such as balconies, signage and even windows through the pendulum effect.

The minimum Fall Distance (or Fall Clearance) should be calculated considering a number of theoretical factors apart from the physical site based ones:
