How to stay safe
- 1Learn the local hazards first — poison ivy/oak/sumac and any regional toxic plants; know what they look like where you camp.
- 2"Leaves of three, let it be" — avoid three-leaflet plants; give sumac (7–13 leaflets, swampy) a wide berth too.
- 3Cover up in risky areas — long sleeves, long pants, and gloves reduce skin contact.
- 4Don't touch or pick unknown plants — and keep them out of shelters, bedding, and fire.
- 5NEVER burn poison ivy/oak/sumac — check firewood and burn piles; urushiol smoke is dangerous to breathe.
- 6If exposed, wash fast — soap and water on the skin as soon as possible (shower or hose, not a bath); wash clothes, shoes, and gear.
- 7Treat a rash simply and get help if serious — keep it clean, don't scratch; seek medical care for a widespread rash, a rash on the face/eyes/genitals, or any breathing trouble.
- 8Never taste-test wild plants — no berries, nuts, greens, or mushrooms without an expert ID.
How to recognize the three
- Poison ivy — three leaflets, a vine or low shrub, no thorns, sometimes white berries.
- Poison oak — three leaflets with rounded tips and fuzzy, lighter undersides.
- Poison sumac — 7–13 smooth leaflets in pairs, in wet, swampy areas, with drooping pale berries (harmless sumac has red, upright berries).
Common mistakes & safety
- NEVER burn poison ivy/oak/sumac. Urushiol in the smoke can cause serious, even life-threatening breathing reactions — the single most dangerous mistake, and it applies to firewood and burn piles.
- Wash exposed skin fast with soap and water. The sooner the better; shower or rinse rather than bathe (a bath spreads the oil), and wash clothing and gear too.
- Get medical care for severe reactions — a widespread rash, a rash on the face/eyes/mouth/genitals, signs of infection, or any difficulty breathing.
- Never eat unknown wild plants, berries, or mushrooms. Many are toxic and some are deadly — a confident expert ID is required, always.
- Watch where you sit and grab — nettles and irritating plants; and remember pets and gear can carry urushiol back to you.
Going deeper
- "Leaves of three, let it be." The one rule every scout should know cold — plus sumac's swampy 7–13 leaflets.
- The smoke is the sleeper danger. People know not to touch poison ivy; fewer know that burning it can send urushiol into the lungs — check every burn pile.
- The oil lingers. Urushiol stays active on clothes, gear, tools, and pet fur for a long time — wash everything, or you'll re-expose yourself.
