I can see X✋︎ poison sumac ✋︎X Toxicodendron vernix

• If contact with smoke, seek ⚕︎ medical attention with all due speed.

• I met a guy whose petrol/​gasoline hedgeclippers went through poison ivy before he noticed — plant fragments hit his lungs, the poison entered his bloodstream, hitting all body organs horribly, and putting him under ⚕︎ medical care for months.
• Perhaps a 😷 P100 HEPA respirator/​filter mask would have helped, but I suggest sufficient PPE and ✂︎ hand tools, nice and slow!

• If contact with ✋︎ skin, quickly remove the oily-feeling urushiol with alcohol and a rag, or with 🧼💦︎ soap and water.  I read that after 10 minutes, most of the agent has been absorbed into the skin — so if you notice contact, try to remove within this time.
• If contact with 👕︎ clothing or 👟︎ shoes, wash them.  For fabric, use normal laundry (some sources say in hot water;  this author finds warm water adequate).  For leather and suede, we have no idea (this author finds re-contact from 👟︎ boots and 🧤 gloves minor).
• If contact with 🐕︎ pets, we have no idea.
• If contact with ✂︎ tools, I try to avoid touching the blade until it has gone through soil or non-Toxicodendron wood a few times.

👥︎ People differ greatly in their reaction to this plant — some react strongly, some are immune, and most are in the middle:

• On contact with the skin of susceptible individuals, a rash appears in a few hours to a day or two.
• Without treatment, it clears up in 7 to 14 days.
• With treatment, it clears up in a week or two.
• This author finds minor contact ignorable.  But If the urge to itch is strong, an antihistamine spray or pen (perhaps with 2% diphenhydramine) [disrecommended by this source] , perhaps followed by (after letting previous soak in) a commercial pink lotion, offers adequate relief for a few hours — use and repeat as directed by the labels.
• One time, when this author had unseen contact with X✋︎ Pacific poison oak  Toxicodendron diversilobum ✋︎X on the job, covering 100% of 💪︎ both arms, with patches on trunk caused by urushiol moved during a 💦︎ post-work shower, I did seek ⚕︎ medical attention.
