Dubai Traffic Sign

During our last exhibition in Dubai we saw this traffic sign.
The screw connections at the foundation were covered with simple PVC-Tubes. They should protect against harmful environmental influences, such as dirt, sand and humidity.

We were curious and look a closer look. All bolted joints were loose.

The problem:
The insufficient sealing of the PVC-tubes promoted the penetration of micro sand in the threads. This caused the loosening of the joints.
