All untreated wood cut offs are perfectly fine and don't give off anything

However, in the case of Painted or Pressure Treated Wood (low-grade wood
for
outdoor use) they should not be burned and only thrown in the trash for the
landfills (yes, your cheap wood or plastic composite deck is very far from
ecological), because they're full of petroleum distillates and pesticides.

All wood releases toxins and for that matter anything burned does too, yes
even your favorite cut of meat with grill marks or toasted bread is a now a
carcinogenic delight. Chimney liners, Stove pipes, Flues, Fireboxes and Ash
bins or pits should be scrubbed clean annually and handled as a Hazardous
Operation with all debris staying off you and going immediately to the
outdoors by a strong fan(s) or into a HEPA filtered vacuum.



Be cautious when burning wood scraps, they burn much more intensely than
typical fire wood.
Scrap woods are much dryer and a little goes a long way as far as heat
out put. I would advise against building a large fire inside of a fire
place with just scrap wood.


Also take care with softwoods - they'll build up layers of
creosote in the chimney liner, leading to higher potential of
chimney fires.
