Here you will find information on topics specific to fall protection.

The information is short and to the point. We have provided links to sites with more in-depth information wherever possible.

The topics are listed in the side menu.

Es wurde bereits sehr viel geschrieben und behauptet zsuspensiontrauma_drammen_craneum Thema Hängetrauma:

Suspension trauma is a potentially life-threatening condition due to limitation of blood flow in the body after hanging vertically for an extended period of time, for example in a fall harness.

Because of this risk, it has been internationally determined that a fall victim must be pulled up within 10-20 min., with the equipment on site.

This timeframe can usually only be achieved when a rescue plan is thoroughly taken into consideration before work on the site begins.

Wikipedia has an excellent, in-depth article with further links on the subject.

Although there have been multiple deadly accidents worldwide involving suspension trauma, there are no official statistics due to the rare occurrence of these accidents.

But the facts remain:

  1. Only a few minutes hanging in a harness can be torture for an injured person --> àTry it out yourself.
  2. The risk of sustaining an open wound in such a situation is usually quite high.
    The risk of bleeding to death is just as high as that of suffering from suspension trauma.

Therefore: rescue scenarios should be discussed and practiced before work begins.

The necessary fall zone has to be taken into consideration while working with fall protection equipment, regardless of the situation.

Goal:
Impact during an accidental fall must be prevented!

The required fall zone can have a radius between .5 and 10 meters, depending on the system components and placement of the anchors.

The important factors are:

  1. Placement of the anchors (directly above the worker, and above head height wherever possible)
  2. Total length of the ropes
  3. Dynamic stretching of the ropes.
    For example: the dynamic pull of a EN1891 rope is 5%!
    A wet rope can stretch up to 1.5x more than a dry rope!
  4. Extension of shock absorbers
    = the effective, fall dependent, extension length
    → A lower fall height will only extend the absorber a fraction of the distance
    →A specialist should be able to calculate the correct extension length
  5. Stretching of the harness
  6. Distance between the attachment point on the harness and the workers shoes
  7. A safety reserve of 1m

Here are a few example calculations for a safe fall zone:

Example 1: Height safety device with an overhead anchor point

Example 2: 2m rope with an anchor point below the waist

Example 3: 1.5m rope with an anchor point at shoulder height
