Work Positioning vs Fall Arrest
There are two approaches to managing risk of falls, and the system used depends on the situation and the work to be undertaken.
Prevents the operative from getting into an unsafe working area.
Typically a fixed work positioning lanyard would be used from a fixed anchor point of a length short enough (normally 2m or less) preventing the user from coming close to an unprotected edge.
Arresting a fall with the minimum impact on the operative.
Fall arrest systems allow the operative to move around freely but in the event of a fall the forces on the body are minimised through appropriate shock absorption. This can be achieved through the shock of absorbing lanyards or the use of a fall arrest block
