oops thats what I got a carbon monoxide detector.
I fired up the forge for the first time in the new shop, like I mentioned before at the old shop ( 18' cieling warehouse) I had more success pushing air alot of air into the shop but at the new shop I Installed a 24" barn fan up high in the wall about 8' off the ground (cielings are 12') and the detector didn't even register anything stayed at zero for the 3 hours I ran the forge with the doors closed.

Thanks! How far fwd do I need to cover? The forge will be belly level, and the floor of my loft is 8' up. It looks like I'll fabricate some kind of hood to protect the ceiling, and get rid of as much heat and exaust as possible, and supliment that with an exaust fan high on the wall if required. Now I just need to figure how big to make the hood/heat guard.

Oh, do I need anything over the forge itself, of just the front edge and "dragons breath" zone.

Thanks!!!

Being on the subject of poisonous gas, what kind of poisonous gasses are in coal smoke?
