What material is specified for overhead coverings for site clearing equipment?

The specified material for overhead coverings for site clearing equipment is steel plate or woven wire mesh due to their ability to provide robust protection. These materials are designed to withstand potential falling objects and debris that may occur on construction sites, thereby ensuring the safety of both workers and the equipment itself.

Steel plates are particularly effective because they have a high weight-bearing capacity and can absorb impacts without being easily penetrated. Similarly, woven wire mesh offers a sturdy barrier while allowing for some visibility and airflow, which can be important in certain applications. Both materials significantly help in creating a safe working environment by effectively mitigating hazards associated with overhead loads.

In contrast, plastic sheeting and fabric tarps lack the durability and strength needed to offer adequate protection against heavy falling objects, making them unsuitable for use in this context. Wooden planks, while offering some level of shielding, do not provide the same level of reliability as metal or wire mesh options. Therefore, using steel plate or woven wire mesh is the best choice for ensuring safety in overhead applications in site clearing operations.
