A flat top trailer was used to transport a liquid storage tank (approx. 1m cubed holding almost 430 litres) via a staging area to a rig location. During transit on a lease road, the driver noticed that the load had shifted and stopped to assess the situation. The driver attempted to pull the load back into position by tightening the securing strap. The ratchet strap was tightened until it would not ratchet any further. It was then released to take another bite. When the ratchet was released, the load shifted and fell, coming to rest alongside the trailer. The driver and a crew member were positioned in a safe zone. Nobody was injured. There was no damage to equipment or harm to the environment.
