Are there any special considerations when using wood with a copper-based preservative?
Following the safety rules (below) regarding cleanup should be sufficient. However, these newer products are extremely corrosive to steel and aluminum. Fasteners and construction hangers/ties should be rated for use with the new wood. Any aluminum flashing should be covered with an impervious layer of a non-corrosive material such as tar paper or non-permeable plastic sheets to prevent contact with the wood.
