Often mistaken for
Poison ivy is a close relative that carries the same oil. It can climb by aerial roots, while Atlantic poison oak always stands upright. Atlantic poison oak's leaflets have deep, rounded lobes, and its leaves are hairy on both sides.
Atlantic poison oak's leaflets are lobed like the leaves of white oak. But a white oak leaf is a single blade on its stalk, while each leaf of Atlantic poison oak is made of three leaflets.
Fragrant sumac has three lobed or coarsely toothed leaflets as well, but its fruit is red and fuzzy. Atlantic poison oak's fruit is greenish white to tan, with fine hairs.

Handling
Every part of Atlantic poison oak carries urushiol, the oil of poison ivy, and it is never safe to handle at any stage, even when dormant. Touching it gives most people a red, itching rash with blisters and swelling, and clothing and tools that touched the plant pass the oil on. Never burn it, since the oil rides on the soot and the smoke can injure the lungs. Wear long sleeves, long pants, boots and gloves near it. After contact, wash your skin, clothing and tools with soap and water, and wash a pet that brushed against it.
