Hello, are you concerned with proper handling of chromated copper arsenate (CCA)? Do not worry, this article will discuss in finer details the precautions and proper ways of dealing with CCA treated wood.
Wood that has been treated with chromated copper arsenate has been used widely across the world since wood has got a long lifespan. CCA consists of copper, arsenate and chromium. Copper acts as a fungicide, arsenic acts as an insecticide while chromium binds these chemicals to the wood.
Preservation of lumber is done by immersing the wood in the chemicals under high pressure to force the ingredients into the wood. Most wood treated with CCA has a green color. However, wood weathering makes it difficult to differentiate from untreated wood.
Analysis from the environmental protection agency shows that CCA-treated wood poses no unreasonable hazard to the environment or public. However, this agency advises that one should avoid the exposure to this chemical either inhaling or contact to the skin.
Exposing yourself to arsenic for a long time can be very harmful to your health. Using wood that has undergone chemical treatments for your home can be dangerous. Always wear a dust mask, gloves and goggles. Sawing, sanding and machining of this wood should be done outdoors. All waste and debris should be disposed immediately. You should never burn CCA treated wood. You should wash your body parts that have been exposed to this wood thoroughly.
To reduce leaching of arsenic to the ground from structures built with this wood, a ground cover such as pea gravel and tire chips should be applied around the structure.
Disposal of this wood should be done only in municipal waste landfills and construction and demolition debris landfills since they are authorized by the government.
If you want to counter the risks that are associated with this wood you can use other alternatives such as plastic lumber, composite lumber, naturally decay-resistant wood and metallic- constructed structures.
