Protection from poisonous plants

With the warm weather approaching, outdoor workers will have to make a special effort to avoid poison ivy, oak and sumac. Approximately 85 percent of the general population develops a rash from the allergic reaction to these poisonous plants. The rash starts within 12 to 48 hours after contact and can be acute or chronic. Chronic or long term exposure increases the severity of the symptoms, which can lead to a recurrence of rashes and permanent scarring.

Employees should be trained to recognize the plants and know how to avoid them. They should wear protective clothing and gloves. Upon exposure, they must wash thoroughly with soap and water and remove all contaminated clothing for washing. They can apply barrier cream to exposed skin. Employers should keep rubbing alcohol accessible to remove the oily resin up to 30 minutes after exposure.
