Many plants are poisonous to humans when ingested or through skin contact with plant chemicals. The most common problems with poisonous plants arise from contact with the sap oil. Several plants native to the United States can cause an allergic skin reaction. These include poison ivy, poison oak, and poison sumac.
Any workers who spend time outside are at risk of exposure to poisonous plants. Some jobs include farmers, foresters, landscapers, gardeners, painters, roofers, pavers, construction workers, laborers, and mechanics. Forestry workers and firefighters who battle forest fires are at additional risk. They can develop rashes and lung irritation from contact with damaged or burning poisonous plants.
