X🔥︎ DO NOT BURN 🔥︎XAvoid all contact with smoke.

  • If contact with smoke, seek ⚕︎ medical attention with all due speed.
X⛽︎✂︎ DO NOT USE HEDGECLIPPERS ✂︎⛽︎X.  Neither petrol/​gasoline nor electric:

  • 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 maximum PPE and ✂︎ hand tools, nice and slow!
X✋︎ ☠︎ DO NOT TOUCH ☠︎ ✋︎X. To avoid skin rash and irritation phytophotodermatitis PPD, due to contact with phototoxic furanocoumarins, leading to ¿permanent damage, disfigurement and blindness?, avoid contact with all parts of this plant [1] with your ✋︎ skin, 👕︎ clothing, 👟︎ shoes and 🐕︎ pets:

  • If contact with anything, seek ⚕︎ professional medical advice with all due speed.  This author has heard of chemical causing permanent disfigurement of skin if the victim fails to stay out of the sun for or years (photo​toxic and phyto​photo​derma​titis).  If contact with the eyes, I read it can cause blindness.  Seek someone with more knowledge than me.  Now.
  • Don't delay.  The toxin is activated by UV light, and UV gets you outdoors, even in the shade.
