Testing of fall protection equipment before use

Fall protection is your lifeline when working at a height or depth. Before you begin your work, it is important to do a thorough visual inspection and test of the equipment.

Start by securing a stable anchorage that can withstand a drag of 1,200 kg. Review your equipment and be aware that the following factors will affect any fall:

  • Fall length (fall length and ground clearance)
  • The body weight of the falling person
  • The ability of the equipment to absorb the load
  • The surface and placement of the equipment on the body
  • The direction of the force in the body


What is fall factor?

The shorter the drop length you have, the less clearance you will need.
Three fall factors are considered:

Fall factor 0 = Anchorage over head height.

Fall factor 1 = Anchorage next to the harness (d-ring on the back or chest)

Fall factor 2 = Anchoring at the feet


Fall factors 0.1 and 2

Calculate the length of the fall and your clearance

When working with fall arresters, calculate the ground clearance (height below the work site).

An example might look like this:

The length of the line  2 meters
Released energy absorber  1.75 meters (find the number for your product in the user guide)
The height of the user
 2 meters
Safety margin  1 meter
Free lift
 6.75 meters


Calculation of ground clearance



Use of a fall block (SRL) will significantly reduce the fall length.
