I was replying to a post and this came to my mind. My employees keep complaining about the chemical smells in the reclaiming room and how hard it is to be in there.
We are on a warehouse and didn't want to spend too much money on making separate rooms for a few things so we bought a wood garage for screen making/reclaiming. That is where we reclaim our screens.
As for ventilation we have a powerful bathroom vent (cost us $300, really pulls air out) which made it better and we now have a fan for air circulation as well.
Still, they tell me the air is not breathable and they wear masks for reclaiming. They are asking for yet another fan for air to go both ways (which is ok, those are cheap).
What sort of setup do you have to make it easier for your guys?
