All upright elements must be individually secured against tipping so that they can NEVER tip over. This means that they must be secured before the couplings are released during loading, and the securing must not be released before the wall is coupled during unloading. In many cases, it is very difficult to secure the wall because the securing must be done during a lift (while the wall is connected); however, in such cases, the wall must be temporarily secured with straps or similar devices before final securing is performed. The same procedure applies during unloading.
An unsecured vertical element poses an immediate danger to life and will result in a FATAL ACCIDENT.
