If employees decide to use ground-marking paint to identify poisonous plants,they should discuss this tactic with the Manager(and Client as appropriate)for approval. • If removal of the plants is considered, it should be subcontracted to a professional landscaping service that is capable and experienced in removing the plant. If herbicides are considered for use, a discussion shall need to occur with the Manager(and Client as appropriate)to determine whether it is acceptable to apply herbicides at the work site.Application of herbicides may require a license. • Employees shall not attempt to physically remove poisonous plants from the work area unless a clearing procedure, including PPE, is prepared in advance and approved by the SH&E Manager.The clearing procedure should be included in the SH&E Plan and THA and the required PPE specified. 4.8.2 Poisonous plants that employees should recognize and take precautions to avoid include: poison sumac, poison ivy(terrestrial and climbing), poison oak, giant hogweed2(or giant cow parsnip), wild parsnip, devil's club and stinging nettle. Many others are extremely poisonous to eat(e.g., poison hemlock; water parsnip)—do not eat anything that has not been identified. Refer to S3AM-313- ATT5 Plants of Concern for information on locations where some of these poisonous plants are found in the U.S. • Of the toxic plants in the cashew family, poison ivy(Rhus radicans)is most widespread. It grows in a variety of forms such as a low sprawling shrub, dense ground cover, or a thick woody vine that grows high into the tree canopy. Poison oak(Rhus diversiloba)is typically a low shrub in drier soils. Both of these plants have leaves of three and white berries. Poison sumac(Rhus vernix)is a tall shrub that is less prolific in distribution. It grows in wet areas, has a compound leaf with a red leaf stem (rachis), and white berries.All of these plants possess urushiol oils in all parts of the plant.Touching the plant causes an itchy skin rash that can show up within 4-72 hours following contact. People have a wide range of reactions including swelling, itching, rash and bumps, patches or blisters. • Uroshiol oil can also transfer onto clothing and equipment. The oil can remain active on surfaces for up to 5 years and can be transferred to your skin. 2 Phytodermatisi producer: keep skin covered and wash well after exposure Wildlife,Plants&Insects(S3AM-313-PR1) Revision 6 July 31,2019 PRINTED COPIES ARE UNCONTROLLED.
