What woodworker doesn’t know the pleasure of wiping a delicate film of very fine dust off a well-waxed jointer bed? Kirk Kundtz, an internist and active woodworker, loves the feel of sawdust in any form, but his concerns about how it irritates the eyes and lungs led him to research its effects on the respiratory system. Here, he talks about how much has to be inhaled to be dangerous, explains the respiratory system, and how dust affects the lungs. He addresses woods that contain toxins, such as in red cedar. Side information by Theodore J. Fink, also an internist and also a woodworker, discusses how to decrease dust production, capture it, and protect your body from it with masks and goggles.
