   You should isolate the open flames from the shop. The easiest way would be to build a closet for the units with adequate sized and typed filters to allow for combustion air, or get the combustion air from outside the shop.

   You probably won't generate enough dust to create an explosion, but the problem comes fro the accidental spillage of finishes and solvents. It is also possible, if venting your DC to the outside, to starve the units of air.

   thanks for the response. I have been dreading the prospect of trying to wall in the furnace, between the ductwork, plumbing, and wiring around it, I don't see how I can effectively isolate it. I wonder if there is any way to provide outside air directly to the burner, i.e. isolate only the burner. Probably wishful thinking, damn, nothing is easy.

   This issue has been discussed here before; most will opt for some sort of enclosure (even modest) for the boiler/hot water heater just to be on the safe side; but strictly speaking, it is not necessary, at least as far as dust is concerned. If you use your DC religiously, there won't be enough ambient dust in the air to create a problem.

   You don't have to be obsessive, but I would make an effort to keep the shop clean and not let the dust accumulate.

   However, solvents are different. If you intend to do finishing in the space, then I think you should definitely build some sort of enclosure. Even then, you will probably not want to work with anything where the solvents are heavier than air -- such as contact cement.

   Without doubt follow Micheal's advice isolate the water heater and furnace.Bring in combustion air (Check the local codes for opening sizes per btu input)from outside .Though you can install filters between appliences and shop the dust will still permeate and block filters on the furnace faster,dry out blower bearings etc.Secondly if due to pressure of work you forget to change the filters in the partitions you may starve the burners of combustion air.This is bad news they can then produce CO result possible death.Be sure that you have an effective CO alarm in the house.Thirdly once you have it all running, turn on all exhausts to the house (range hoods,bathroom fans etc.) and check for possible backdraft of waterheater and furnace exhaust.

   Hi,

   I would be concerned about possible propane leakage. Gas could collect in your basement with the possibility of an explosion. Be very careful with all connections, if there are any rubber hoses observe their 'expiration' date as these can become porous. For added safety you can install a gas detectors. There are low cost, battery operated units on the market, like smoke detectors.
