Toxic woods
A list of woods that are known to cause allergic, toxic, infectious, or respiratory reactionsOne of the worst hidden dangers in woodworking comes from the key material all woodworkers use in their craft: the wood. A number of species from around the world are known to cause allergic, toxic, infectious, or respiratory reactions.
This list of woods compiled by Fine Woodworking author Stanley Wellborn for an article in Fine Woodworking issue #9 includes most of the species that are known to cause a reaction of some type. Although researchers point out that not everyone is sensitive to these woods, they warn that woodworkers should be particularly cautious when sanding or milling these woods.
