As when doing any home improvement project, all safety precautions must be taken when handling materials and tools, including, but not limited to, the use of eye protection, gloves, safety guards on saws, and all power tools. Also, a safe work environment should be maintained which includes children and pets being absent from the construction area.
Armadillo composite decking acts very much the same as wood. Being heavier in weight, use the same precautions you would when handling natural materials. Store for long periods of time flat, with support every 2 feet. Do not attempt to lift similar volumes of Armadillo composite decking boards as if they were wood.
