What are two important things when storing wet scaffolding planks and  how do you maintain scaffolding materials?

• Wet planks should be stacked on level bearers well clear of the ground with spacers between each layer.

• Locate the stack in a dry, well ventilated location and align spacers with bearers. A minimum of three spacers per layer is recommended.

Note: Dry Planks should be stored under cover

Use WD-40 or a like product on bolt threads and nuts to prevent rust and lock up: It is important to ensure any moving or removable part remains fully functional. This improves safety, maintains efficiency.
