Why is the wood are harmful?

Wood can be harmful primarily due to the potential presence of mold, fungi, and pests that may thrive in damp conditions, leading to health risks like respiratory issues or allergic reactions. Additionally, certain types of treated wood may contain harmful chemicals, such as arsenic or chromated copper arsenate (CCA), which can leach into the environment. Furthermore, wood dust generated during cutting or sanding can be a respiratory irritant and may pose long-term health risks. Proper handling and treatment can mitigate these dangers.
