Many woods can cause skin irritation and allergies. Some of these woods include South American boxwood, cocobolo, ebony, American and African mahogany, mansonia, rosewood, walnut, East Indian and other satin woods and Western Red Cedar.

Chronic inhalation of sawdust can cause chronic respiratory diseases. Cocobolo, ebony, African mahogany, mansonia, rosewood, and satinwood can cause respiratory irritation and allergies. Beech, iroko, Western Red Cedar, and teak can cause severe asthma. South American boxwood, cork oak, and redwood can cause an acute illness resembling pneumonia.

Plaster Molds and Casts

Plaster of Paris (calcium sulfate) is irritating to the eyes and slightly irritating to the respiratory system.

Heat builds up when plaster sets and can be dangerous enough to cause serious burning when casting parts of the human body.
