Rigid Rail Fall Arrest Systems provide shorter free-fall distances, reduced risk of secondary fall injuries such as swinging into obstacles, and no negative impact on a second worker in the event of a fall. So, in short the answer is SAFETY! Below are the four points to remember when choosing the right fall arrest system for your company.
Less Fall Clearance Distance
Wire rope systems require additional fall clearance due to the initial sag of the wire. The dynamic sag, or the stretch of the rope during a fall, adds to this distance. A rigid rail fall arrest system stops the fall sooner by eliminating any sag, stopping the fall in a much shorter distance than the wire rope.
Reduced Risk of Swing Fall Injuries
Injuries occurring after the fall, such as swinging into obstacles, are minimized with a rigid rail fall arrest system, which stays firm and minimizes the total fall distance. When a worker falls on a wire rope system, the wire’s sag will make the trolley slide to the center of the nearest two supports, creating a risk for the worker to collide with nearby obstacles after a fall.
Longer Distances Between Supports
A rigid rail fall arrest system allows for longer distances between supports, reducing both material and installation costs.
After a Fall
The worker can continue use of a rigid rail fall arrest system after a visual inspection. A wire rope system must be replaced and recertified by a qualified engineer.
