What should workers avoid doing on the platform of a digger derrick?

Climbing or sitting on the platform's edge is a critical safety concern in the operation of a digger derrick. Doing so can significantly increase the risk of falling, as the edges are not designed for stability or support. Maintaining proper positioning within the boundaries of the platform ensures that workers are safeguarded against potential accidents.

While other activities, such as using the platform as a staging area or working without safety gear, also pose safety issues, the specific action of being on the edge is especially precarious and directly compromises worker safety. It's essential to adhere to established safety protocols, which include staying away from precarious edges to prevent falls and injuries while operating such equipment.
