Wood Toxicity
|
If you are uncertain about the health
risk of a wood you are using, please check its toxicity level before you
start working with it. Wood dust is dangerous. (See Dust
Collection.) Some people are allergic to the wood
itself. Cocobolo dust frequently causes a reaction like poison
ivy. The dust from Chakte Kok and Aromatic Cedar can irritate the
sinuses. Use the following chart on Wood Toxicity. Below the
chart are links to articles and more charts on the toxicity of wood.
Keep your woodworking hobby enjoyable by staying healthy. |
