Using a mobile access tower on soft or uneven ground is hazardous because these surfaces do not provide the necessary stability and support that the tower requires. If the ground is soft, the weight of the tower can cause it to sink or tip over, leading to potential falls and injuries to users. Uneven ground can create an imbalance, making it difficult to securely establish the base of the tower.

In contrast, a flat concrete surface offers a stable and secure foundation, significantly reducing the risk of accidents. Gravel or sand may also present some stability issues but are generally less problematic than soft ground. Wooden decking typically has a level surface, although care must be taken to ensure it can support the weight of the tower. Safety regulations emphasize the importance of using mobile access towers on sufficiently stable and level ground to mitigate the risk of collapses and to ensure the safety of workers using the tower.
