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

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!
