Some people are sensitive to certain species of wood, wood dust, or wood oils. Eye, respiratory, and skin irritation can occur, and can be extreme in some cases. All woods, regardless of species, produce sawdust that is harmful when inhaled.

Because of this, we always recommend using appropriate eye, nose, and skin protective equipment when working with wood. When working with an unfamiliar species, be sure to assess the potential for any adverse reaction prior to starting a project.

The chart below lists woods known to cause reactions in sensitive individuals. It is not intended to cover all species:
