Poison ivy and poison oak (Toxicodendron species) are the main causes of occupational contact dermatitis in outdoor workers. Toxicodendron dermatitis accounts for 10% of all lost-time injuries among members of the US Department of Agriculture Forest Service. As many as 25% of forest firefighters need to leave the fire line because of severe Toxicodendron dermatitis. Forestry workers may also develop woodcutter's eczema, an allergic reaction to airborne SQLs in Frullania plants. These liverworts grow on tree trunks in the American and Canadian Pacific Northwest.
