No, because you can get the allergic reaction from the plant in your lungs. That would suck. Even if the doors were closed, you would still have the smoke going elsewhere. I got my first case of poison ivy in a campfire, and it got everywhere that wasn't covered with clothing. It was awful. Don't do it!!
DO NOT burn poison ivy, oak, or sumac to get rid of it. The resins can be spread via smoke, and can cause severe reactions in people who are far downwind.
Not a good idea. Some varieties of sumac contain the same toxic chemical as poison oak.
no
Yes it can
Check with Martin for an owner's manual. Unless a fireplace is specifically rated as multi-fuel, a gas fireplace cannot safely burn wood.
No, it is not safe to burn. It is toxic.
