I am a plumbing contractor by trade, I a questionable about some upcoming work and need a little input. I have an interior finish out coming up, and they have already installed the storefront. I can get my 17 inside, but of course I am concerning about carbon monoxide buildup inside the lease space. If I placed a couple of large shop fans in the front and back doors do y'all think I could work for a couple of hrs and not be hurt? I just don't want to create myself a problem, just trying to save some back work if at all possible. Yall's input would be greatly appreciated. Thanks for reading.
