Be careful if you build in your basement and decide to install an exhaust fan for fume / sawdust removal. If your home heating furnace happens to be there also and it is either a gas or oil fired unit you could possibly starve it for air when turning on the exhaust fan. This could cause the flame to be sucked into the basement or flue products sucked back from the chimney. Gas or oil fired hot water heaters can cause problems too. There are other problems that can arise but these are the worst ones that have a great potential for death.
